Unlike their more sleek-headed cousins, hammerheads’ mallet-shaped noggins (while a little cumbersome) serve a very specific purpose. In true shark fashion, it has everything to do with hunting prey. Their unique head shape in part gives these sharks binocular vision; with eyes on either end, their field of vision is quite broad and allows them to view a great deal of their surroundings at once. Additionally, that big head has a lot of extra space inside to store specialized sensory organs that detect electrical fields produced by other marine life. Since hammerheads’ favorite meal—stingrays—tend to hide under the sand, this is especially helpful. Once they find a ray, they use their wide heads to pin them to the ocean floor.
