Info from Licensor: "I was diving at this dive site all week, with tons of sea lions all over the place. One large male checked me out every day, barking, and blowing bubbles. On my 5th day of diving, the sea lion became much more aggressive, attacking me from behind by grabbing my shoulder when I was looking. He then made a bunch more passes at me, before biting my camera and breaking the dome port! I then swam away and he left me alone."
