Two sea lions caused commotion and panic when they came out on a beach in San Diego's La Jolla area and started running after people.
Beach lifeguards were on standby in the water, making sure no one was injured and that the sea lions could easily find their way out to sea.
Scientists believe that sea lions suffer from a lack of natural prey which forces nursing mothers to forage for food at sea, leaving their cubs to fend for themselves for longer. The disruption to the food chain around the main marine mammal colonies is thought to be caused by rising water temperatures, which in turn is caused by unusually weak winds along the west coast.
