Shark Whale
The biggest fish in the world is a whale shark. It is not dangerous as it lives on plankton, which is made up of tiny plants, fish eggs and larvae. This huge fish can reach 15m (50ft) in length.
Shark belong to a very old family of fish that have skeletons of hard gristle rather than bone. Other members of this family are rays, dog fish and saw fish. They can be found in many parts of the world, but usually in tropical waters.
