Hammerhead sharks use their oddly shaped heads to improve their ability to find prey. Their wide-set eyes give them a better visual range than most other sharks. And by spreading their highly specialized organs over their wide, mallet-shaped head, they can more thoroughly scan the ocean for food. Hammerheads have also been known to use their heads to pin stingrays against the seafloor.
