As per a new study, Hammerhead sharks can hold their breath to survive almost freezing-cold waters during deep dives.
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 watersnear 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.
