Hammerhead Sharks have a distinctive and unusual head structure. Their heads are laterally flattened and extended to form a ‘cephalofoil’ or ‘hammer’ shape which they are named after. Hammerhead Sharks are mostly found throughout the world in warm waters. Hammerhead Sharks are olive-green to gray-brown in color on their tops. Their undersides are white in color. They have heavy serrated and triangular teeth. Individuals can easily identify their extra-tail and pointed dorsal fins.

During the day, these sharks are hunt and swim together (in schools). At night, they become solitary hunters. These types of sharks are aggressive hunters. They normally feed on octopuses, small fish, crustaceans, and squid. Normally, they do not actively eat on human prey. However, when attacked and provoked, they become more than defensive.

Nine species of Hammerhead Sharks exist. The Great Hammerhead is the largest of them all. It can grow close to 20ft (6m) in length and weigh close to 1000lbs (450kg). However, there are smaller sizes, which are very common. Of all the species, only the great hammerhead is believed to pose danger to humans. This is mainly because of its aggressive nature and large size.

Hammerheads are mostly found in tropical and temperate waters worldwide. They are normally seen migrating in masses during summer as they seek cool waters. You can find these sharks between one to three hundred meters in depth. Their hot spots include Hawaii, Costa Rica, and Colombia.

Their head comes in handy as a sensory organ. It helps these sharks to detect many things such as electrical fields, which are normally created by the prey animals. The head enables the shark find favorite meal. Stingrays stand out as the hammerhead’s favorite food. These sharks normally consume this food in large amounts.

Hammerheads usually give birth to pups. They are hatched from egg cases originating from the female uterus. In one litter, these sharks can give birth to numerous pups, sometimes as many as forty.
