Goodbye, Adaa

Very sad news this morning. Adaa, who made the record as the oldest male sea otter in zoos and aquariums at 22 years and two months, died on Sunday. Some excerpts from Seattle Aquarium’s announcement:

We are sad to announce the passing of Adaa, the male northern sea otter under our care, from cancer. The disease was diagnosed in mid-February and considered terminal. Adaa was treated with medications to manage his symptoms and provide him with a good quality of life for the time he had left. The staff had hoped this would give him several weeks, but his condition recently deteriorated and he was humanely euthanized on Sunday, February 27.

Curator of Birds and Mammals Julie Carpenter describes Adaa as “a beautiful animal with a gentle way about him. He had his quirks, such as hopping with his rear flippers when on land instead of walking and making soft cooing sounds while chewing.”

“He was a gentle male and was always amazing with the females,” says Julie. “In his older years he was often seen holding onto Mishka, a younger female, while he slept and was even seen grooming her.”

Adaa had some favorite enrichment activities, like playing with or crunching on ice and solving puzzle feeders. He will be dearly missed by the staff and volunteers at the Aquarium and by the many in-person and live-webcam visitors who enjoyed his company.

“Adaa had an enormous amount of trust in the people who cared for him,” says Senior Veterinarian Dr. Caitlin Hadfield, “particularly the animal care professionals who worked most closely with him. It was always inspiring to see that relationship. It allowed us to work together to provide the care he needed as he got older.” 

We’ll miss you, Adaa.
