What are Hammerhead Sharks?

About Hammerhead Sharks:

• Hammerhead Sharks are characterized by a flattened hammer- or shovel-shaped head.
• These distinctive heads serve multiple purposes, including granting the sharks 360-degree vision as well as better hunting abilities.
• There are nine species of Hammerhead Sharks, each with varying lengths. The great hammerhead shark is the largest of all hammerhead species, reaching a maximum known length of 20 feet.
• They are exothermic animals, meaning that they have no internal way to control their body temperature.
• Distribution:
  • They are widely distributed in tropical and temperate marine waters near the coasts and above the continental shelves. 
  • They may migrate seasonally, moving equatorward during the winter and poleward during the summer.
• Features:
  • The upper sides of these fish are greyish-brown or olive-green, and they have white bellies.
  • They have very impressive triangular, serrated teeth—like the edge of a saw's blade.
  • The hammerhead also has special sensors across its head that helps it scan for food in the ocean. 
  • Unlike many fish, hammerheads do not lay eggs. A female gives birth to live young.
