Hammerhead Shark
Hammerheads are easily recognized by the unique shape of their head, which resembles a flattened, double-sided hammer. They have a U-shaped mouth filled with triangular teeth and eyes on the sides of their head. They are olive-brown or grey-brown on their dorsal surface and white below. Sometimes their pectoral fins have dark tips. Hammerheads can grow to over four metres in length and weigh more than 400 kilograms.
