Farewell to Barney

It’s a very sad day at the Seattle Aquarium as we say goodbye to Barney the harbor seal. As we shared last September, in a story commemorating his birthday, Barney was quite old: At 39, he was roughly the equivalent of a 100-year-old human—and one of the oldest known harbor seals in human care.

Beloved by many, Barney will be deeply missed and remembered always with love.

Director of Animal Health Dr. Caitlin Hadfield and members of our veterinary and animal care teams had been working closely with Barney for years, making sure he was as happy and comfortable as possible. Just like many elderly humans, he developed some age-related health issues over time but overall had been doing well.

Recently, however, he showed an acute decline. Based on his prognosis and how he was feeling—his quality of life—the team made the difficult decision to humanely euthanize him on the morning of March 14. “We know that many in the community will join the Aquarium’s staff and volunteers in mourning this loss. Barney will be remembered and missed,” says Aquarium President and CEO Bob Davidson.

Barney was the first harbor seal to be born here at the Aquarium, in 1985. He shaped many caregivers over his long life and was cherished by all, particularly for his easygoing and inquisitive nature. “I knew Barney for 19 years and my appreciation of him only grew as time passed,” comments Animal Care Specialist Cheryl Becker. Dr. Caitlin Hadfield, who had worked with Barney since joining the Aquarium in 2017, notes, “Barney had great trust in his human caregivers and his home. He had a number of health concerns over the last few years and we learned a lot from each other. I’m proud of the care the animal care staff provided, and that we were able to help ensure that his end of life was peaceful.”

Barney will be remembered as a wonderful, one-of-a-kind ambassador for the Seattle Aquarium. “He inspired a stronger curiosity about the ocean in millions of people—a curiosity that inspired action for conservation of our marine environment,” says Bob Davidson.

Even at his advanced age, Barney clearly relished his favorite foods.

“In my childhood bedroom is a box filled with my most precious memories. Paramount among them is a series of photos of me as a child at the Seattle Aquarium, including one where I’m smiling beside a harbor seal who happens to be Barney! In many ways, subtle and overt, he played a role in shaping who I am. Choosing a career in animal care, grounding my purpose in life to bring people’s focus and empathy to conservation, staying committed to being silly in my age and, of course, only eating what I want. In the two decades since the photos were taken, I had the immense pleasure of playing a small role in caring for Barney. Thank you, Barney, for watching me grow, encouraging me to learn, allowing me to try to pay it all back in fish—thank you Barney, thank you.”

Barney was a beloved icon here at the Aquarium and, over his nearly 40 years, touched the hearts of countless visitors, volunteers and staff. Says Supervisor of Birds and Mammals Mariko Bushcamp, “Barney and I were the same age and I knew him for nearly half my life.” She speaks for all of us when she adds, “You’ll leave a big hole—but thank you for all the memories, Barn.”

Dive down memory lane with us to celebrate Barney’s birthday bash!

Barney the harbor seal was born right here at the Seattle Aquarium on September 14, 1985—that’s right, 39 years ago! And he’s been stealing the hearts of staff and guests alike ever since, while inspiring millions to help protect his beloved and charismatic species.

“Barney remains one of the oldest harbor seals in human care—possibly the world—that we know of,” notes Curator of Birds & Mammals Veronica Seawall. Here at the Aquarium, we have a number of geriatric, or elderly, animals entrusted to our care, and our expert team works hard to create environments that meet their evolving needs as they age. (Interested in learning more? Read all about how we provide expert animal care at every age.)

Now that Barney’s in his golden years, he enjoys the simple things in life, like a nice nap in the sunshine, getting his teeth brushed daily and eating some of his favorite snacks, including all things fish. He’s also a fan of his birthday celebrations, as you’ll see in the photos below. Dive down memory lane to revisit some of those celebrations with us as we commemorate Barney’s 39th!

2024

Centennial celebration—happy 39th, Barney!

According to the Association of Zoos & Aquariums (AZA), of which we’re proud to be an accredited member, the median life expectancy for harbor seals in zoos and aquariums is about 25 years. At 39, Barney has lived well beyond that. In fact, his biological age is about the equivalent of a 100-year-old human!

Give him—and his caretakers—some love on our Facebook or Instagram to mark the occasion.

2023

38 years young!

Barney’s 38th birthday bash was complete with a “cake” made from ice and 38 frozen fish!

2022

37 looks good on you

We welcomed harbor seal Casey earlier in 2022, and all three “roomies”—Barney, Hogan and Casey— dug into a delicious, fish-filled ice treat together.

2021

Having his cake and eating it too

Barney rang in his 36th birthday by tucking into a towering ice treat “cake.”

2020

Pandemic party

While we couldn’t invite the public to celebrate with Barney because of our temporary, pandemic-related closure, our incredible animal care team made sure he felt the birthday love.

2015

Just another enriching birthday

Animals at the Aquarium receive enrichment every day (read more about it on our webpage). Special occasions, like Barney’s 30th, give our animal care team a fun reason to get creative with it.

2013

28 and looking great!

In 2013, Barney celebrated his birthday with cake in his habitat’s new haul-out space*! Generous support from people like you allowed us to renovate and expand the harbor seal habitat back then.

*What’s that? Space that the seals use to go onto dry land to nap, groom, cooperatively participate in their own health care and, in Barney’s case, eat a birthday treat.

Your gift today will make a difference too: Please consider a donation of $19.85, $39 or any amount on behalf of Barney’s birthday!

2012

Awww, you shouldn’t have

Shown here in the habitat’s previous haul-out space, Barney looks ready to devour the ice treat that our animal care team prepared for him.

Stealth celebration

What’s better on your 26th birthday than a delicious ice treat, just waiting for you to notice it as you casually swim by?

2010

Blow out the candles!

Here’s a throwback to Barney’s 25th! Our animal care team went all out with an ice treat complete with “candles” for him to crunch and munch.

How’s this for a sweet, vintage photo of newborn Barney alongside his mom, Clyde? For perspective on how long ago that was in terms of other Pacific Northwest icons, Barney was born the same year that downtown Seattle’s tallest skyscraper, Columbia Center, opened; two years before the band Nirvana was formed; and 15 years before the Kingdome was demolished. Just our humble opinion, of course, but we think he’s the best and most charming icon of the bunch. Happy, happy 39th to beloved Barney!

Health care for feathered friends at the Aquarium: A birds-eye view

This story is part of our series, The Doctor Is In—highlighting our veterinary team’s expertise in service of animal wellbeing.

It’s not just marine mammals at the Aquarium who are trained to cooperatively participate in their own health care. The birds entrusted to us participate in their own care too. How do they do it? By eating!

“Animal care staff can closely monitor food consumption to help assess health,” says Supervisor of Birds and Mammals Sara Perry. “We count how many and what type of fish or bug each bird eats during the day. Overall behavior during a feeding can tell us a lot about the wellness of the bird as well.”

When feeding alcids (including the common murres, rhinoceros auklet and tufted puffins in our care), staff can also deliver specific vitamins or necessary medications, expertly hidden in a tasty fish. It’s similar to how parents of young children may “hide” vegetables in a favorite food!

The comparison to human children doesn’t stop there: Animal care staff often need to be creative and patient when feeding birds. “They’re not like a sea otter who will usually eat anything at any time, or a seal who just gulps fish down. Ask any of our staff, feeding the birds takes finesse!” Sara laughs. “We rely on our knowledge of each bird, their behavior and their preferences—depending on time of year—and apply it to a group setting.”

"You look like you haven't aged a bit!"

Here at the Seattle Aquarium, we have a good number of elderly birds in our care. But it’s hard to know that just by looking at them. Why? Birds don’t show graying of feathers as they age, unlike the graying or lightening of hair and fur of mammals (including us humans!)—so it’s not possible to estimate age based on that indicator.

Birds do show other age-related changes that are seen in mammals, though. For instance, their mobility and vision may deteriorate over time, their appetites may change, and they may rest more than younger birds. “Our Aquarium staff know each bird as an individual, which allows us to adjust feeding and spaces to help the older ones,” comments Director of Animal Health Dr. Caitlin Hadfield. “It’s all in the name of taking the best possible care of each bird at the Aquarium for their whole lives.”

Did you know?

All the birds (and mammals) at the Seattle Aquarium fall into one of two categories—they were either born at a zoo or aquarium or they were rescued and have been deemed non-releasable according to the guidelines established by government agencies such as the U.S. Fish and Wildlife Service and policies such as the Migratory Bird Act.

Urchins, anemones and sea stars, oh my! Invertebrate care at the Seattle Aquarium

This story is part of our series, The Doctor Is In—highlighting our veterinary team’s expertise in service of animal wellbeing.

Invertebrates—animals without backbones—are found in every habitat at the Seattle Aquarium. And, like all animals entrusted to us, they need expert care to thrive. “Our goal is to provide great quality of life in an enriching environment for the animal’s whole life,” says Director of Animal Health Dr. Caitlin Hadfield, MA VetMB MRCVS DiplAZCM DipECZM, “And that goes for all the animals under our care.”

“All the invertebrates get checked by Aquarium staff at least once every day,” she comments, “Their environmental conditions are checked as well—that includes evaluating the water and the systems that support it.” Although some invertebrates may seem like fairly simple animals on the surface, managing their care, says Dr. Hadfield, presents some interesting challenges. One of them stems from tracking the number of animals of each species because some, like corals, can be colonial. “It gets tricky,” says Dr. Hadfield. “Do we track this as one animal—a coral head certainly looks like one structure—or as the thousands of polyps that make up that structure?”

A small colony of pink swiftia coral.
Almost all corals are colonial organisms, meaning that what may look like a single animal is actually many—sometimes hundreds of thousands!—of animals, called polyps, living together.

Even invertebrates need primary care providers

Regardless of how they’re counted, invertebrates, like all the animals at the Aquarium, are part of our preventative medicine program. Aquarium biologists are on the front lines of animal care, making careful observations of each animal at least once a day. “Our staff are experts at evaluating the animals they’re caring for and are able to identify subtle changes in their appearance or behavior,” says Dr. Hadfield. Because all animal care staff have the training and experience to make these evaluations, each animal at the Aquarium has the equivalent of a PCP, or primary care provider, who has the best understanding of their health history and needs.

Routine exams, in many cases, are also part of the Aquarium’s preventative medicine program (yes, even for invertebrates!). “A big part of that is reviewing the animal’s history,” says Dr. Hadfield. “For that, we rely on the knowledge of our animal care specialists and the information in our record systems.” Along with that review, an invertebrate checkup might involve a physical exam, fluid collection or ultrasound, depending on the animal’s needs. Sea urchins need their teeth checked, too!*

*Surprise­—sea urchins have teeth! They’re arranged in circle at the bottom of the urchin’s body.

All for one, one for all

When doing health checks, it’s important to consider all the animals in a habitat. “If an animal isn’t eating well,” notes Dr. Hadfield, “It could be normal for that time of year or life stage, but it could also be because there’s something wrong with that animal, the other animals around it, or the world it’s living in.” In those cases, animals that show symptoms first can become “canaries in the coalmine” for issues that might affect neighboring animals. Closely monitoring individual animals can keep smaller problems from spreading and becoming bigger.

Expert animal care at every age

This story is part of our series, The Doctor Is In—highlighting our veterinary team’s expertise in service of animal wellbeing.

Our highest priority is providing the best possible lives for the animals in our care—nearly 18,000 fish, invertebrates, birds and mammals with the opening of the Ocean Pavilion. At the forefront of this work are our veterinary, water quality and animal care teams, whose members monitor the health of the animals every day.

Director of Animal Health Dr. Caitlin Hadfield, MA VetMB MRCVS DiplAZCM DiplECZM, is the veterinarian in charge: performing routine observations, interpreting records with animal care staff, providing treatments for animals when needed, and undertaking physical examinations routinely and when concerns arise.

Not surprisingly, some of those issues of concern are related to aging. Geriatric* medicine has become a focus for animal care specialists at zoos and aquariums accredited by the Association of Zoos and Aquariums (AZA)—including yours truly—for the best possible reason: as we continue to learn and share information, animals are living longer and longer lives.

*The term “geriatric” refers to older individuals, whether human or another kind of animal. Just as elderly humans require specialized medical care, other elderly animals do as well.

Caring for aging animals at the Seattle Aquarium

Here at the Aquarium, we have a number of geriatric animals in our care. For instance, Barney the harbor seal turned 38 in 2023, reaching a biological age that’s about the equivalent of a 100-year-old human!

And, at age 22, Adaa the sea otter was the oldest sea otter living at an AZA-accredited zoo or aquarium in the U.S. at the time of his passing in 2022. He was also the oldest male sea otter on record in the AZA studbook.*

*What’s a studbook? It’s a document that keeps track of information such as age, significant events like births or deaths, parentage and taxonomy (or the science of classifying and naming organisms). Staff at zoos and aquariums like the Seattle Aquarium work with the AZA to maintain regional studbooks for a wide variety of species. This demographic history is an invaluable tool to help guide conservation projects.

Aging is a complex process that refers to changes in all the systems and functions of an animal’s body; however, aging develops at different rates in different species. Some species of Pacific salmon, for example, have a very brief life (chronologically), dying soon after a single spawning event when they are a few years old. Spotted lagoon jellies also have shorter life spans—just three to four months. Rockfish, on the other hand, may live for over a hundred years!

Evolving care over time

The goal of geriatric care is to maintain the best possible quality of life for the individual animal during a time when they would normally be vulnerable to predation or unable to source food for themselves in the wild. Geriatric care at AZA-accredited zoos and aquariums, like ours, is respectful to each individual animal—for their life and its intrinsic value.

What that care involves differs by species and by individual. Our animal care staff work hard to create and maintain environments for aging animals that are safe and easy to use. This can be challenging for the variety of species living together in our larger habitats, such as the Window on Washington Waters and Underwater Dome. In those instances, Aquarium aquarists use their understanding of animal behavior and feeding preferences to provide the best environment possible.

Some species of rockfish—like this tiger rockfish—can live to be well over 100 years old.

How does care evolve over time for marine mammals at the Aquarium? As these species begin to reach—and exceed—their chronological life expectancy in the wild, animal care staff may begin to adjust how they work with them. For instance, as mammals age, their risk of contracting several age-related eye diseases (such as cataracts and macular degeneration) increases, just as it does in aging humans. If visual acuity (or keenness of perception) is reduced, the Aquarium’s animal care specialists introduce more verbal and tactile cues, such as gently brushing past their whiskers. Arthritis (also known as degenerative joint disease) is also common in all mammals as they age. Just as it does for humans, management may include anti-inflammatories, joint supplements, diet modifications and adapting the environment to meet the mobility needs of the individual.

Watch our care team welcome a critically endangered bowmouth guitarfish in need of a safe home

It’s difficult to describe a bowmouth guitarfish. It’s even harder to see one in the wild.

The bowmouth guitarfish (Rhina ancylostomus) has been in its current form for millions of years—and it shows. These prehistoric-looking, blueish-grey fish appear to be part ray, part shark and even part dinosaur. They sport gills on their undersides, a telltale sign that they are, in fact, rays 

A bowmouth guitarfish swimming along the rocky ocean floor.
Bowmouth guitarfish, solitary by nature, often live in coastal areas.

Elusive and endangered

Though they live close to shore, sightings are rare. The bowmouth guitarfish is classified as “Critically Endangered” on the International Union for Conservation of Nature (IUCN) Red List of Threatened Species®, meaning they have an extremely high risk of extinction.

Earlier this year, the Seattle Aquarium had an unexpected opportunity to provide a safe home to a bowmouth guitarfish pup. And next summer, visitors to the Aquarium’s new Ocean Pavilion will have the chance to be part of her surprising story.

And then there were nine!

The pup’s mother was caught in a commercial fishing set net off the east coast of Taiwan. What happened next surprised everyone: while in a holding pool at the fishing center, the mother gave birth to nine live pups.

Our conservation partner in Taiwan, Fred Fan of Fred Fan Aquatics, quickly diverted the animals to a safe place. He then contacted the Seattle Aquarium to work on finding them a long-term home. There are no marine-protected areas where the mother was caught, and fishing for bowmouth guitarfish is legal throughout many regions of Asia. As a result, releasing the mother and pups would have put them at risk of getting caught in another net.

Pups provide hope

The existence of nine bowmouth guitarfish pups in one place felt both miraculous and daunting.

Fan and the Seattle Aquarium contacted additional conservation partners in the region and North America, knowing that accredited aquariums have animal care and species recovery expertise.

Late one night in January 2023, the pups—donated by Fan—arrived from Taiwan to the Seattle Aquarium’s offsite Animal Care Center. There, eight pups would quarantine and receive care for several weeks before moving to teams at the Georgia Aquarium, Shedd Aquarium and Disney’s Animals, Science and Environment. And one female pup would remain in Seattle.

No time to waste

Globally, around 400 species of elasmobranchs—sharks and rays—are threatened, largely due to overfishing. In fact, an estimated 100 million individual sharks are killed by people every year. Fishing records for bowmouth guitarfish suggest we’ve lost more than 80 percent of the species in recent years.

Meanwhile, accredited aquariums have been caring for bowmouth guitarfish since 2005. In 2014, a bowmouth guitarfish pup was born in an aquarium for the first time.

We’re still learning about these solitary, elusive fish. We know that they live in relatively shallow, coastal waters, where they stay close to sandy bottoms. They like to crunch on the crustaceans and mollusks they find on the ocean floor. (The bowmouth guitarfish who will live at the Aquarium’s new Ocean Pavilion eats restaurant-quality, sustainably sourced lobster, shrimp and bony fish.)

Though bowmouth guitarfish are rare, they are also wide-ranging. They’re found in coastal areas throughout the Indo-West Pacific, including from South Africa north to the Middle East, South Asia, Southeast Asia, north to Japan and south to Australia. This range provides the chance for many communities and people to be part of the effort to restore their numbers.

Sharing knowledge is key

In November 2023, Fred Fan, aquariums from across the world, academic partners and conservation leaders met at Shedd Aquarium in Chicago to discuss the role aquariums can play in preventing bowmouth guitarfish from going extinct, as well as the structure and development of programs to aid in their recovery.

Restoring wild populations requires trust, partnership, expertise, genetic diversity of the species and time—the least available resource a critically endangered species has. Even so, there’s hope and a highly committed team of marine scientists, researchers and care experts working on these plans.

Beginning next summer, when you visit the Ocean Pavilion, you’ll meet the bowmouth guitarfish in our care and learn how you can join efforts to advocate for the survival of this ancient, fascinating species.

“Like human nurses—but in the veterinary field:” All about vet techs at the Seattle Aquarium

This story is part of our series, The Doctor Is In—highlighting our veterinary team’s expertise in service of animal wellbeing.

Veterinary technicians—or vet techs—are an integral part of the veterinary care team here at the Seattle Aquarium. But what does it mean to be a vet tech, and what kinds of education and experience are needed to work as a vet tech in an aquarium setting? Lindy McMorran, BS LVT Cert AqVN /T, and Erika Russ Paz, BS LVT, recently sat down with us to share some details.

First things first: What's a veterinary technician?

“It’s like a human nurse—but in the veterinary field,” explains Lindy. Similar to a nurse in a clinic or hospital, Lindy and Erika might spend a typical day at the Aquarium running anesthesia during a procedure, dispensing medications, taking x-rays, maintaining supplies and equipment for the Aquarium’s Veterinary Care Center and scheduling exams. They may also be found working with animal care staff to train behaviors that help with animal care, such as the ability to give an injection or take a blood sample with an animal’s cooperation.

Both women have Bachelor of Science (BS) degrees—Lindy’s in marine biology; Erika’s in marine science with a minor in biology—and licensed veterinary technician (LVT) credentials. Earning the credential requires about two years of full-time studies, followed by a national exam and state test. (Details, including alternative criteria, can be found on the Washington State Department of Health website.)

Most vet techs go on to work at the kind of veterinary clinic where you might take a pet dog or cat, so the curriculum focuses on their care. Although much of the core training applies to animals of all kinds, “there was no training that was specific to aquatic animals,” notes Lindy.

For vet techs in aquarium settings, that’s where hands-on experience, internships and/or additional courses—not to mention a passion for the marine environment—come in.

Erika Russ Paz standing in the Seattle Aquarium's Veterinary Care Center. She has straight brown hair and wears a blue Seattle Aquarium jacket.
Erika Russ Paz, our newest vet tech, makes use of our Veterinary Care Center to help fish, invertebrates, birds and marine mammals stay healthy.

Says Erika, describing highlights of the path that brought to her to the Aquarium, “I worked as an educator and marine science camp counselor at an aquarium during college. I also interned at an aquarium and as a wildlife rehabilitator. And, after graduation, I spent time as an observer in Alaska, collecting data to help manage our fisheries. I worked with PAWS, caring for a wide variety of species from the Pacific Northwest, as well. ”

That’s in addition to seven years in a general veterinary practice before joining our team early this year. “A background in marine science and biology, along with a passion for the ocean and care of animals, ultimately led me to the Aquarium,” Erika comments.

Specialties: Not just for human nurses

“Human nurses can have specialties, like oncology or pediatrics. Veterinarians can have those same kinds of specialties,” Lindy says. “But for vet techs, specialties are less common.”

Like Erika, Lindy augmented her schooling by working with marine animals—for example, as a volunteer for SR3, a local organization focused on marine mammal rescue and rehabilitation, and here at the Seattle Aquarium. She’s been focused on aquatic animals since 2007: as an intern, a lab assistant, an instructor and more.

Through her years of specific experience with aquatic animals, Lindy recently earned a new credential, Certified Aquatic Veterinary Technician, from the World Aquarium Veterinary Medical Association (WAVMA). She’s just the second person in the continental United States to achieve the certification, which became available from WAVMA at the beginning of 2023, joining select others from around the world.

Put simply, the new credential recognizes Lindy’s expertise with marine animals. “It’s one of the only ways a vet tech in the aquarium field can prove their experience,” she notes. “For instance, there is no board certification specialty for vet techs in aquatic medicine, but there is one for zoos.”

Caring for adorable sea otters is just one perk of Veterinary Technician Lindy McMorran's role.

Broad experience + passion = a well-rounded, expert team

“Growing our veterinary team and seeking people with diverse backgrounds and areas of expertise helps ensure that each animal receives the individual care they need, which benefits their wellbeing,” comments Lindy.

That adaptability, always important, is even more so as the Aquarium expands with the opening of the new Ocean Pavilion this summer. Interested in learning more about veterinary care at the Seattle Aquarium? Check out our web story devoted to the full team.

The doctors (and techs) are in: Getting to know the Seattle Aquarium’s veterinary care team

This story is part of our series, The Doctor Is In—highlighting our veterinary team’s expertise in service of animal wellbeing.

Providing medical care for the animals at the Seattle Aquarium—soon to be nearly 18,000 with the opening of the Ocean Pavilion!—is far from a one-person endeavor. Working to provide excellent animal health and wellbeing requires skill and expertise from a well-rounded veterinary team, one that is required to be available any time of the day or night, every day of the year.

The Seattle Aquarium’s veterinary care team is currently composed of six people:

  • Two full-time veterinarians—Our director of animal health and team leader, Dr. Caitlin Hadfield, MA VetMB MRCVS DiplAZCM DiplECZM and Dr. Sasha Troiano, DVM MS CertAqV;
  • Two relief veterinarians, who are available to step in when our staff veterinarians are unavailable and/or extra support is needed—Dr. Brian Joseph, DVM MFAS CertAqV and Dr. Alicia McLaughlin, DVM CertAqV; and
  • Two veterinary technicians*—Lindy McMorran, BS LVT Cert AqVN/T and Erika Russ Paz, BS LVT.

*Not sure what a veterinary technician is? Be on the lookout for our upcoming web story, in which we’ll introduce you to Lindy and Erika and share some highlights of what they do—as well as details about a prestigious new credential that Lindy recently earned!

Initials = hard-earned credentials

Did you happen to take in the initials following our vet team’s names? They’re credentials—each one representing extensive education and certification.

For instance, staff vet Dr. Sasha Troiano and relief vets Dr. Brian Joseph and Alicia McLaughlin have doctorates of veterinary medicine, or DVMs. The three also have certified aquatic veterinarian (CertAqV) credentials from the World Aquatic Veterinary Medicine Association (WAVMA), indicating their extensive experience working with aquatic animals. In addition, Dr. Troiano has a Master of Science (MS) degree; Dr. Joseph has a Masters of Fisheries and Aquatic Sciences (MFAS) degree.

Lindy McMorran and Erika Russ Paz have Bachelor of Science (BS) degrees—marine biology for Lindy; marine science with a minor in biology for Erika—and licensed veterinary technician (LVT) credentials. In addition, Lindy recently received a certified aquatic veterinary nurse/technician (CertAqVN/T) credential from WAVMA—more on that in our upcoming web story!

As for Dr. Hadfield’s credentials, we’ll let her explain them in her own words:

  • MA: “I did a bachelor’s degree in zoology that included a master’s.”
  • VetMB: “Then I did my vet degree, which goes by those initials at University of Cambridge —the initials vary a bit by school.”
  • MRCVS: “That means I’m in good standing as a member of the United Kingdom’s Royal College of Veterinary Surgeons. It’s an odd requirement from England!”
  • DiplACZM: “These letters are for board certification. This was my first one, with the American College of Zoological Medicine—that’s what the ‘ACZM’ is for. Qualifying to take the exam requires years of clinical experience and publications. That’s followed by a challenging exam—in my case, I specialized in aquatics for my second day of exams, while day one had everything from red-eyed tree frogs to rhinos.”
  • DiplECZM: “I was also able to get certified with the European College of Zoological Medicine—the ‘ECZM’ in the title—and become a ‘diplomate’ of that group.”

Benefitting animal wellbeing beyond the Aquarium's walls

Members of the Aquarium’s veterinary, water quality and animal care teams share their expertise with the larger community in many ways—for instance, serving in leadership roles with the Association of Zoos and Aquariums (a nonprofit, independent organization that accredits zoos and aquariums, including the Seattle Aquarium, worldwide); helping to rescue and rehabilitate stranded animals; participating in research on wild populations; making presentations; collaborating on and authoring papers and articles—and even co-authoring an entire textbook on fish medicine.

That’s right: On top of her regular duties, Dr. Caitlin Hadfield found time to co-author the 624-page Clinical Guide to Fish Medicine. Written for vets, vet techs, biologists and fish enthusiasts, it’s now required reading for zoological board exams.

What kind of exams are those? “Just like your dentist and knee surgeon have done additional exams to confirm their specialization, there are boards for vets who specialize in zoological medicine or specific types of animals,” Dr. Hadfield explains. “Boards require a lot of extra studying and difficult exams. It’s great to be on the required reading list because it ensures a steady stream of readers! But more importantly, it helps set high standards for health care of fish.”

The book was the first of its kind. “There are textbooks that provide practical information on clinical medicine of domestic species—like dogs and cats—that vets can refer to through the day while at work, but that resource just didn’t exist for fish,” notes Dr. Hadfield. “There are good textbooks on fish, but they are focused on specific aspects of fish medicine or particular diseases and aren’t as useful in a busy clinical setting. So we submitted a proposal to the publisher and they accepted.”

A true team effort

For any team to be successful, each member must bring something different and valuable to the table—and that’s definitely the case at the Seattle Aquarium. “I’m really proud of the team’s diverse skills and how we work together and learn from each other,” comments Dr. Hadfield. “We provide care whenever it’s needed: any time of day or night, any day of the year,” she adds, “so we need a team that can be one voice for animal care and wellbeing, and support the wellbeing of the staff and volunteers we work with. That’s a big task given the variety of species in our care.”

And that variety is increasing in a big way with the opening of the Ocean Pavilion this summer. Interested in a behind-the-scenes look at some of the species you’ll find there—and a chance to see Dr. Hadfield and other Seattle Aquarium team members in action? Check out episode six of our Animal Care Stories series. And if you’re curious about what it takes to become an aquarium vet, dive into this great conversation with Dr. Hadfield!

New series goes behind the scenes at our Animal Care Center

Visitors to our Ocean Pavilion will experience underwater life on the other side of the planet. They’ll witness tropical reef ecosystems that face similar challenges to our local waters and meet extraordinary creatures who represent what’s at stake if we don’t work together to regenerate a healthy ocean.

As the Ocean Pavilion rises along our waterfront, we’re welcoming and caring for its future residents in our new state-of-the-art offsite Animal Care Center.

Introducing Animal Care Stories

Our new series takes viewers behind the scenes to see how our dedicated animal care team is preparing for the Aquarium’s historic expansion.

In the first three episodes, our team begins to move animals from the existing Aquarium piers to the Animal Care Center. The team shares their diligent planning efforts and their excitement about the role each animal will play in Ocean Pavilion ecosystems.

It Takes an (Aquatic) Village

At the Aquarium and the Animal Care Center, experts work together across multiple teams. 

  • Animal care team: Aquarists are specialists on the fish and invertebrate species in their care. Nimble, observant and deeply committed, they get to know Aquarium residents on an individual level by caring for them every day.
  • Veterinary team: Every animal at the Aquarium—from tiny to very large—receives attentive and compassionate medical care from our full-time veterinary team. The approximately 110 species who will call the Ocean Pavilion home will receive the same excellent standard of care as our current residents.
  • Water quality team: Our expert water quality team carefully monitors animals’ environments around the clock. They use special instrumentation to track the level of dissolved oxygen, pH, temperature and other conditions in Aquarium habitats. As animals travel to the Animal Care Center, the team uses technology to monitor their trip in real time and does additional testing upon arrival for a holistic picture of water quality.

"The animals we care for are individuals with their own quirks and personalities. My favorite task is feeding; you’re making that connection and providing hands-on care."

Beyond Ocean Pavilion

Even after the Ocean Pavilion opens, the Animal Care Center will provide space for important conservation work. Its facilities will allow us to grow our species recovery programs, including our participation in the global ReShark coalition, dedicated to recovering threatened shark and ray species, and our program to restore pinto abalone in the Salish Sea. It’ll also be home to our plastic pollution research and rehabilitation efforts for stranded or injured marine animals, like Shi Shi the sea turtle.

The Animal Care Center provides vital space to care for new animals that will live in Ocean Pavilion habitats, like those pictured above. The center also supports our broader animal care and conservation work.

Saying goodbye: End-of-life animal care at the Seattle Aquarium

In a recent series of blog posts, we described what it’s like to care for the 12,000+ animals that live at the Aquarium and how we aim to provide the best lives possible for them. This post is devoted to the final stage: end-of life care and, when necessary, euthanasia—which means producing a humane death that is rapid, avoids pain and minimizes any distress. While many of the animals in our care die of natural causes, euthanasia is a critical and compassionate element of the care we provide. No animal can live forever, and we want the animals in our care to pass as peacefully as possible when it’s time.

The Seattle Aquarium has carefully developed a comprehensive set of lifelong care and euthanasia policies and protocols as well as quality-of-life assessments to guide the process of determining when humane euthanasia is called for. These policies and protocols are in alignment with the U.S. Department of Agriculture’s Animal Welfare Act and Animal Welfare Regulations, as well as the standards set forth by the American Association of Zoo Veterinarians and the Association of Zoos & Aquariums. They apply to all animals at the Aquarium, from fur seals to sea stars, as well as rescued animals that we care for (such as sea turtles). These decisions are not taken lightly and always involve veterinary and animal care staff.

Emergency euthanasia and planned euthanasia for health and welfare reasons are two categories of humane euthanasia described in the Aquarium’s policy:

  • Emergency euthanasia may be the most humane and compassionate choice if an animal is in acute distress and we can’t relieve that distress. An example might be a rescued sea turtle with severe injuries from a boat strike that we can’t fix. These situations are always hard, but we do everything we can to minimize pain and suffering. Fortunately, emergency euthanasia is rare at the Aquarium.
  • It’s more common that euthanasia decisions are planned. This is because we monitor our animals closely and usually know when an animal is getting toward the end of its life. This is often due to symptoms that are affecting quality of life and where there are no additional diagnostic, treatment or management options.

“Our harbor seal, Q, was diagnosed with cancer in early 2021,” says Senior Veterinarian Dr. Caitlin Hadfield. “The cancer responded really well to chemotherapy, and he was his normal happy self for several more months. The cancer came back, and we went into what is called rescue therapy. We used his individual quality-of-life assessments, other monitoring and regular discussions with his animal care professionals to help understand how he was doing. We knew that the rescue therapy was unlikely to give him much time, and so we were ready to provide a peaceful euthanasia when we saw signs that he wasn’t thriving.” Q was humanely euthanized in June of 2021.

Regardless of the reason, when euthanasia is deemed necessary, the Seattle Aquarium is committed to always providing appropriate methods that are in the animal’s best interest and that cause the most rapid, painless and distress-free death as possible. 

While the decision to humanely euthanize an animal can be emotionally difficult, it’s also one that needs to be made when the situation calls for it—and we’re grateful for the clear policies and protocols, aligned with governing bodies and best practices in animal care, that help guide us.
