Elderly Gray Seal Dies at Smithsonian’s National Zoo

Elderly Gray Seal Dies at Smithsonian’s National Zoo

November 10, 2016

The National Zoo’s senior female gray seal, Selkie, died today. At 43 years old, Selkie was the oldest gray seal living in human care. The lifespan of a wild gray seal is usually 25 or 30 years. Typically, female gray seals in human care can live close to 40 years; male seals live about 30 years.

Animal care staff had been monitoring and treating Selkie for pain associated with several masses on her abdomen for months. During a diagnostic exam Nov. 8, veterinarians anesthetized Selkie to collect samples of the masses and to screen her abdomen and chest for disease. She recovered well from the exam, and up until this morning, her behavior was normal. A final pathology report will provide more information.

Selkie arrived at the National Zoo in January 1979 from the Naval Oceans Systems Center in San Diego. When she was 6 months old, Navy researchers trained Selkie to perform underwater tasks during the Cold War. Gray seals can dive down to 1,000 feet deep and remain underwater for 20 minutes, so they were considered an efficient and effective means to retrieve items from the ocean floor. In her career as a Navy seal, Selkie learned how to insert and remove equipment, use a screwdriver and turn a large wheel valve.

Most Zoo animals participate in a breeding program called the Species Survival Plan (SSP). The SSP scientists determine which animals to breed by considering their genetic makeup, nutritional and social needs, temperament and overall health. Born in Iceland in November 1973, Selkie’s genes were not represented in U.S. zoos, making her a valuable breeder. Selkie birthed four female pups at the National Zoo. Visitors can see two of them—Kara and Kjya—on American Trail, along with Kara’s offspring, a female named Rona. A male gray seal Gunther and two harbor seals named Luke and Squeegee also share the exhibit.

Gray seals are native to the North Atlantic. North American gray seals typically live on the rocky outcroppings of Canada’s east coast, though scientists have spotted them as far south as New Jersey. The International Union for Conservation of Nature lists the gray seal as least concern. Efforts to stop hunting and reduce the number of seals trapped in fishing nets have greatly contributed to the stability of their population.
