Monterey Bay Aquarium
Monterey Bay Aquarium's Sea Otter Research and Conservation (SORAC) program studies and tries to save the threatened southern sea otter since 1984.
16,000-20,000 animals
, a small group of perhaps 50 otters survived along Big Sur coast, now slowly expanded to nearly 2,800.
Job: to rescue, treat and release injured otters; raise and release stranded pups through surrogate program; provide care for sea otters that can't return to the wild, and conduct scientific research.
The Institute of Marine Sciences in UCSC, has the responsibility to encourage, develop, and support university endeavors in marine science research and education
