GOLETA, CA - MAY 22: California Sea Lions jump out of the water at Refugio State Beach on May 22, 2015 in Goleta, California. California Gov. Jerry Brown declared a State of Emergency after over 100,000 gallons of oil spilled from an abandoned pipeline on the land near Refugio State Beach, spreading over about nine miles of beach within hours. The largest oil spill ever in U.S. waters at the time occurred in the same section of the coast in 1969 where numerous offshore oil platforms can be seen, giving birth to the modern American environmental movement.

A jogger passes a stranded adult sea lion in Laguna Beach, California, on March 30, 2015. Record numbers of starving baby sea lions continue to wash ashore in California and the problem has shown no sign of abating. According to the New York Times, experts suspect that unusually warm waters are causing food to become more scarce, causing the mother to leave their pups on their own while the mother hunts for food. Left on their own, the pups can not find food and become sick and emaciated, swimming to shore to prevent themselves from drowning.

They tried to remove it, but couldn't, so they called in vets from NC State University to help.

They were able to get the battery out and no harm was caused to the sea lion.

Zookeepers say if the visitor had not reported seeing the batteries, the sea lion would have most likely gotten very sick and may have even died.
