Seattle Aquarium sea otter Aniak passes away

SEATTLE, WA — The Seattle Aquarium is deeply saddened to announce that Aniak, one of our sea otters, was humanely euthanized this morning. She was one of three sea otters living at the Seattle Aquarium. 

Aniak was born at the Seattle Aquarium, and at 19 years old was considered a geriatric sea otter. She had chronic skin issues for six years, with animal care staff, veterinarians and dermatologists consulting and adapting her care to make her comfortable while managing the side effects from her medications. In spite of the care provided, Aniak’s health swiftly declined this week. With her welfare, comfort and quality of life in mind, the difficult decision was made to humanely euthanize her.  

Aniak was born at the Seattle Aquarium to Lootas, who was rescued after her mother was killed in a boating accident. Aniak grew up here, and gave birth to Chugach in 2005, who went to live at Pittsburgh Zoo & PPG Aquarium, and to Sekiu in 2012, who now lives at Point Defiance Zoo & Aquarium.  

“This is a sad day for the Seattle Aquarium staff, volunteers, friends, and visitors,” said Grant Abel, Director of Life Sciences. “Many of us have watched Aniak grow up, and in so many ways she showed us why sea otters are such an important part of the ocean ecosystem.”
