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

Posted on May 8, 2024May 9, 2024 by Emma Leiser

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.”

Working toward the clean plate club

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

Posted on April 3, 2024April 11, 2024 by Emma Leiser

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?”

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

Posted on March 26, 2024April 11, 2024 by Emma Leiser

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.

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.

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

Posted on February 23, 2024April 11, 2024 by Emma Leiser

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.

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.”

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

Posted on February 20, 2024April 11, 2024 by Emma Leiser

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.
