Sea Otters
The sea otters are the best-groomed animals at Shedd — and in the ocean. It’s a matter of survival. Instead of blubber to keep them warm in the cold Pacific Ocean, these marine mammals have the densest fur of any animal — up to 1 million hairs per square inch.
All About Sea Otters
There are two subspecies of sea otter, and Shedd is home to both: the northern sea otter (Enhydra lutris kenyoni) and the southern sea otter (Enhydra lutris nereis).
Southern sea otters, like the wild counterparts of Luna, Cooper, Watson and Jade, are found along rocky coastlines and kelp forests in the northern Pacific Ocean from central to southern California. Northern sea otters, like Seldovia, are found in similar habitats in the Aleutian Islands, Southern Alaska, British Columbia, and Washington.
Sea otters are a keystone species, meaning they help keep their ecosystems in balance. In particular, sea otters keep kelp forests healthy by eating sea urchins and other invertebrates that graze on giant kelp. If sea otters disappeared, their ecosystems would become unbalanced and unhealthy. Urchins would strip the kelp beds that many species depend on for food, shelter and nurseries.
Sea otters are classified as endangered by the International Union for the Conservation of Nature (IUCN). It is important that we continue to research, rescue and rehabilitate sea otters in need and conserve and protect their ocean habitats so this important species can thrive.
Evolution of Shedd's Sea Otter Program
Since 2022, Shedd has played a unique role in providing a temporary home for non-releasable female sea otters as they mature and grow to become surrogate mothers. They will one day return to a partner institution in Monterey Bay Aquarium’s Sea Otter Surrogacy Program to raise rescued, orphaned pups for return to the wild.
Surrogates teach the pups critical life skills like how to groom their dense fur to survive cold Pacific Ocean temperatures and how to dive to great lengths to forage for food. This critical program gives orphaned sea otter pups a second chance at life in the wild and helps the wild sea otter population recover to its historical levels in California. Shedd provides this temporary care for non-releasable female otters to support the broader conservation effort for this endangered species.
Meet the Sea Otters
Glistening dark bodies roll in the water. Light-furred faces pop to the surface, then dive back in. For someone without a trained eye, Shedd Aquarium’s sea otters look an awful lot alike. And they seldom stay still long enough for you to try to discern differences. To help you figure out who's who, here are each otter’s key characteristics.
