At at the age of 20, this beautiful southern sea otter named Brook is the oldest female otter in human care. In fact, she’s likely the oldest female in the entire otter population as they generally tend to live about 15 years. Brook lives at @aquariumpacific and is often seen lounging on her pile of ice. Otters have the densest fur of any animal on the planet, and eat approximately 25% of their body weight per day, which explains why Brook weighs a healthy 40 pounds!
Because southern sea otters are currently listed as threatened under the Endangered Species Act, the conservation work of places like @aquariumpacific is essential in maintaining their species. The Aquarium works to raise and care for sea otters, and recently partnered with the University of California, Santa Cruz, to study hearing thresholds in otters-- the first research of its kind.
