is the great hammerhead shark ectothermic or endothermic?

Question

why is it ectothermic or endothermic. this is for a school project

Answer 1

The great hammerhead shark is ectothermic (cold-blooded), though five other species of shark, including the great white, have been found to be endothermic.

Answer 2

The hammer shape of the head was once thought to act as a wing, aiding in close-quarters maneuverability and allowing the shark to turn sharply without losing stability. However, it was found that the special design of its vertebrae allowed it to make the turns correctly, more than its head. But as a wing the hammer would also provide lift; hammerheads are one of the most negatively buoyant of sharks. Like all sharks, hammerhead have electrolocation sensory pores called ampullae of Lorenzini. By distributing the receptors over a wider area, hammerheads can sweep for prey more effectively.[1] These sharks have been able to detect an electrical signal of half a billionth of a volt. The hammer-shaped head also gives these sharks larger nasal tracts, increasing the chance of finding a particle in the water by at least 10 times as against the ability of other 'classical' sharks.

Wider spacing between sensory organs better enables an organisms to detect gradients and therefore the location of a gradient source such as food or a mate. The peculiar head of this shark can be thought of as analogous to the antennae of an insect.

Answer 3

shark is a fish, all fish are ectothermic (cold-blooded meaning they depend on the temperature outside their bodies), while mammals are endothermic
