The dogfish shark grows up to around 3 feet in length. It feeds on small fish and invertebrates. The whale shark, the largest of all fish, can reach up to 50 feet in length. It is the least dangerous one. These sharks have many razor-sharp teeth. The great white shark, the greediest monster, swallows its prey as a whole. The remains of big animals, such as seals, dolphins and smaller sharks have been found in its stomach.
A shark will eat almost anything found in the sea, from the tinniest sort of sea creatures to other sharks, turtles, seals or dolphins. They have been known to swim up rivers and attack crocodiles, horses and elephants that might have waded into the water. They are also found to attack people swimming in the sea. In the pursuit of their prey, they can move very fast. They follow the ships to feed on the waste food thrown overboard from the kitchens of the ships. Some sharks live and hunt alone, while others prefer to roam the seas in packs.
