Since 1985, biologists and veterinarians at the California Department of Fish and Wildlife and the USGS Western Ecological Research Center have collected and examined all reported sea otter strandings — counting the number of dead, sick or injured sea otters recovered along California each year — in an effort to understand the population trends of the southern sea otter and to inform resource management on recovery and conservation of the species. Relative to river otters, sea otters have flattened molars for crushing prey rather than tearing. Sea otters are members of the weasel or mustelid family. While the males and the females don’t live in the same rafts, they don’t seem to show aggression towards each other when their habitats overlap either.
