California sea lions wash up along our Pacific Coastline every year, often malnourished, many starving, or because they've been exposed to marine toxins, parasites, or physical traumas. Many are rescued by The Marine Mammal Center, north of San Franscisco. To aid in their health assessments, we wish to assess their social behaviors before they're released back into the ocean. Right now, several malnourished yearlings are recovering at the Center.
