Fishermen get the surprise of their lives when a massive beast flops on their boat

A group of fishermen were totally baffled when a monstrous sea lion hopped on the back of their boat.

According to the description in the viral YouTube video presumably written by video uploader Peter Ladey , the men were out at sea off the coast of California.

It seems like the sea lion just wanted a bite to eat, and the fishermen happily helped them out.

"Sea Lion hanging out on the back of our boat being fed the finest of fish, and what a friendly little pal he was. Not sure what the bump on his head is though," the description added.
