Shark aggressively bumps scuba diver's camera in Belize

Reef sharks are one of the ocean's most magnificent predators. They are sleek and graceful in their movements, and frighteningly powerful. With rows or razor sharp teeth and tremendous jaw strength, they are formidable hunters. But they are also one of the ocean's most misunderstood animals.

Shark attacks on humans are rare. Unprovoked attacks are even more rare. For the most part, sharks are scavengers and opportunistic feeders that prey on the weak and dying creatures. In this way, they keep populations healthy, ensuring that only the strongest of a species is allowed to reproduce. Without sharks, many animal populations would not be kept in check and the effect on the balance of the reef would be devastating.
