In science lessons about oceans and adaptations, the hammerhead's wide head lets it see all around and helps it sense the tiny electric signals of prey, like stingrays hiding in the sand. Some hammerheads swim in big groups called schools. Several kinds are endangered because of overfishing and shark finning. Phrases: great hammerhead, scalloped hammerhead, a school of hammerheads.
