Uni Sushi is a female southern sea otter. She was found as a tiny pup stranded on a beach near Santa Cruz in 2018, and was brought to the Monterey Bay Aquarium's rescue and care program. Unable to be paired with a surrogate mom, she was eventually deemed non-releasable by the U.S. Fish and Wildlife Service, and a permanent home was found for her at the Oregon Zoo.
The marine mammal care team named the pup "Uni Sushi" (uni is the Japanese word for sea urchin), in honor of the diet of sustainable seafood she and the rest of the sea otter family enjoy.
