You may want to think twice about entering the ocean.

This amazing footage shot September 1 shows a great white shark swimming towards a 22 year old man off the coast of Santa Barbara, California.

The man said he thought his friends were messing around with him by pulling on his diving fin. it wasn't his friends though. it was a great white shark biting on his toes.

The man had dropped his spear gun was able to pick it up in time as the shark swam towards him. He was able to jab it which sent it swimming off.

What's really scary is this happened in only ten feet of water.
