A shark proof cage is an extremely strong, metal cage used by a scuba diver to safely examine dangerous types of sharks up close. This can include various species of shark, but the most commonly observed within the confines of a cage are the great white shark and the bull shark, which are both known to be aggressive at times. Shark proof cages are built to withstand being rammed at high velocities, and be able to protect the user from massive force from attacks. Cages can provide a visual and tactile deterrent to sharks. Cage-diving allows people to closely monitor sharks, and sometimes interact with them.
