A shark proof cage is a cage which is lowered into the ocean, and in which a SCUBA diver enters, to examine sharks up close more safely. Shark proof cages are built very strong, in order to withstand the strength of a shark ramming the cage. However, many such cages are not actually shark proof, as a determined shark can still compromise the cage. Rather, they provide a visual and tactile deterrent to the shark. Cage diving allows people to get up close to potentially dangerous sharks, like the great white shark and the bull shark.
