Senior Seal Celebrates Birthday

Shelby the harbor seal celebrated her 21st birthday at the Aquarium of the Pacific in Long Beach. Seals in the wild have an average lifespan of about 15 years, so she’s a senior citizen in the seal world. Due to her age, Shelby has lost about 90 percent of her eyesight, but her incredible sense of hearing allows her to whip around her habitat with the best of them.
