The hammerhead shark is one of the most recognizable shark species around.

of other shark species, and hunting is easier when they seek out prey along the bottom of the ocean. Nature has helped make this hunting preference easier by providing an off-white belly that helps disguise the hammerhead when viewed from underneath. The upper coloring is gray-brown, sometimes olive green. WIDE VARIETY Scientists currently have discovered ten different kinds of hammerhead sharks. Hammerheads live between twenty and thirty years. They all share the distinctive hammer-shaped nose, but each species has a slightly different design to this hammer. The smallest hammerheads are only 3 ft. (.9144 m) long and weigh less than 7 lbs. (3.18 kg). The largest, the great hammerhead, can grow up to 20 ft. (6.096 m) in length and weigh as much as 1,200 lbs. (544.3108 kg). This variety in size makes it difficult to create general statements about this species because each has special traits that set it apart from the rest. Like humans, however, there are some traits that are shared by all.
