Keep your eye on the shark at all times. Sharks may retreat temporarily and then try to sneak up on you. Don't let this happen. To be able to defend against the shark, you must know where it is, so make every effort to watch the animal, even as you're trying to escape.

 

 

If you have nothing around you, use your own body. Aim for the shark's eyes, gills, or snout with your fists, elbows, knees, and feet.
