About Sharks

There are more than 450 species of sharks today including the great white, hammerhead and tiger shark. Species range in size from as small as 17 centimetres to 12 metres long. Sharks are usually found in oceans as deep as 2,000 meters.

Many sharks, are apex predators meaning they are at the top of the food chain in their environments. While some sharks are omnivores, most are carnivores and display an array of different feeding techniques.

Unlike other fish, sharks reproduce a small amount of well developed young. Most sharks live to be about 20 or 30. The largest shark, the whale shark, may live to be over 100 years old.

Despite what people believe, shark attacks on humans are unlikely. Out of the 450 species only four have been known to attack and kill people. In fact, sharks are threatened by humans due to habitat loss, coastal degradation and fishing. It is estimated that over 100 million sharks are killed each year.
