Oldest Harbor Seal on Record Turns 48!

At 48 years of age, Skinny is more than a super senior–she’s currently the oldest living harbor seal on record.

In nature, harbor seals can live into their late teens, while those in human care can live into their twenties—or, as in Skinny’s case, well beyond.

 “Skinny has been alive longer than her caretakers,” said Brittany Blades, Oregon Coast Aquarium’s Curator of Marine Mammals. “She’s seen it all. There have been major changes in animal husbandry practices over the last 50 years, and she’s adapted amazingly.”

Blades began working with Skinny 12 years ago, building a foundation of trust that would benefit them both. As it turns out, you can teach an old seal new skills. Thanks to patience, positive reinforcement, and the dedication of Aquarium mammalogists, Skinny surpassed expectation after expectation, and is now the most self-assured seal at the Oregon Coast Aquarium.

Skinny continues to learn and practice new behaviors. During training, the marine mammals learn to lie down on cue, follow a target, hold a pose, and more. These skills come into play during medical exams, allowing the animals to participate in their own care.

Just like humans, harbor seals are prone to arthritis, cataracts, and other age-related ailments. Aquarium mammalogists are well-versed in looking after geriatric animals, and provide Skinny with specialized treatment to ensure she stays healthy and comfortable through her golden years, including acupuncture, laser therapy, and chiropractic adjustments. During a recent electrocardiogram to check up on her heart health, Skinny knew exactly what to do. On her cue, she followed, rolled, and held still as veterinary staff got to work. Twenty minutes later, the results were in:  Skinny remains as healthy as ever.

Skinny’s longevity reflects her status as a survivor. In 1975, Skinny was just a pup when she was found stranded on a beach in Washington, orphaned, dehydrated, and starving. After receiving immediate care she was deemed non-releasable, and found a temporary home at Point Defiance Zoo & Aquarium in Tacoma, Washington.

She came to her permanent home at the Oregon Coast Aquarium just before its grand opening in 1992, and has been a fan favorite ever since. Skinny is easy to identify thanks to her sleek silver fur and wide eyes. Her caretakers joke that Skinny doesn’t blink—if she did, another 48 years might just fly by.

Skinny will continue to live out her retirement at the Aquarium, charming visitors, volunteers, and staff alike. Considering her age, every day with Skinny is a gift.

“Earning Skinny’s trust, watching her progress, and growing with her has been a highlight of my career,” said Blades. “It’s truly been an honor.”
