â¢ Hammerhead Sharks. There are several species of hammerhead sharks, which are in the family Sphyrnidae. These species include the winghead, mallethead, scalloped hammerhead, scoophead, great hammerhead and bonnethead sharks. These sharks differ from other sharks, as they have very unique hammer-shaped heads.
There are more than 350 different kinds of sharks, such as the great white and whale sharks. Fossils show that sharks have been around for 420 million years, since the early Silurian. Most sharks are predators, meaning they hunt and eat fish, marine mammals, and other sea creatures. However, the largest shark eats krill, like whales. This is the whale shark, the largest fish in the world.
