Description

The mallethead shark is a small hammerhead (Sphyrnidae) from shallow coastal waters of the eastern Pacific, off Central and South America. The species grows to about 92 cm and has the typical, flattened hammer head, with the eyes at the ends. As a predator it hunts small fish, crustaceans and squid in turbid coastal water and river mouths.
