The sea lion is basically the petty thief of marine animals.

Check out this video taken while shooting an episode of the reality show 'Chef on the Water' in Cabo San Lucas. The fishermen are proudly displaying their haul when a sea lion jumps out of the water and swipes one of the fish quicker than you can say "Darned sea lion!"

The suspect, known in the area as Pancho, is apparently notorious for pulling stunts like this. Darned sea lion!
