Starving Baby Sea Lions Washing Up On California Beaches

SAUSALITO, CA - FEBRUARY 12: Two sick California sea lion pup sit in an enclosure at the Marine Mammal Center on February 12, 2015 in Sausalito, California. Scientists are struggling to figure out what is causing hundreds of sick and starving California sea lions to wash up on on California shores over the past three winters. Nearly 500 of the extremely emaciated pups have been found since the beginning of the year and are being treated at rehabilitation centers throughout the state. The Marine Mammal center has cared for over 170 of the pups so far this year. (Photo by Justin Sullivan/Getty Images)
