Why Are Hammerhead Sharks Shaped So?

Though sharks have been around for over 450 million years, the Hammerhead sharks are the most recent species to evolve – just 20 million years ago. Hammerhead sharks are called so because of the strange hammer-like shape of their heads. The function behind their strange heads is still under speculation.

Some have suggested that the shape of the head helps the shark to swim more efficiently, others have hinted that the hammerheads have a larger number of electroreceptors which are useful for detecting prey buried underneath the sand. More ludicrous reasons include using its head as a battering ram, as well as to pin down prey.
