One freediver had a close call with an aggressive sea lion while spearfishing off the coast of Santa Barbara, California. Chris Okamoto was using his GoPro to film the open ocean when a colony of sea lions swam around him, according to the Daily Mail.
"At first, it looked like they were just curious," Okamoto told the Daily Mail. He said he had been in similar situations before, "but this one came much closer and as soon as it rushed toward me, I swung the butt of my gun up and it stopped short."
While rare, sea lion attacks on humans do occur. California sea lions can be aggressive and territorial, and the National Oceanic and Atmospheric Administration advises the public to stay at least 50 yards away from them while they are swimming.
