Tubarão-martelo

The Tubarão-martelo (Sphyrna spp.) is a genus of shark, has a length between 1 to 6 meters and is characteristic for the projections on either side of the head, which is located the eyes and nostrils. The Tubarão-martelo is an aggressive predator that consumes fish, cephalopods, stingrays and other sharks. It occurs in temperate and warm oceans in all areas of the continental shelf. They are gregarious animals that travel in swarms of up to 100 copies. The hydrodynamic shape gives a faster time to turn his head. It also carries a greater number of ampullae of Lorenzini, which is used to detect magnetic fields as tiny as the heartbeat of small fish.
