The sea lion pup, which weighed only 25 pounds, was transported to Marine Mammal Care Center at Fort MacArthur for rehabilitation. All along the California coast, sea lions have been getting stranded in great numbers since January for reasons unknown. The National Oceanic and Atmospheric Adminstration estimates that in the first three months of 2013, more than 900 malnourished sea lions have been rescued in the region compared to 100 during the same time period one year ago. Officials have declared an 'unusual mortality event' for the California sea lion, a designation that prompts immediate federal response. (Photo by Kevork Djansezian/Getty Images)
