Hammerhead shark

Diet: Hammerhead sharks are aggressive predators which eat fish, rays, other sharks, squid, octopuses and crustaceans.

Where they live: shallow tropical and warm temperature sea.

Surface and Skeletons: a hammerhead shark’s skeletons look like a hammer. Since sharks do not have metal (a kind of) bones and rarely become fossils, it is their teeth alone that are commonly found as fossils. The hammerheads seem closely related to the carcharhinid sharks (a kind of shark) that evolved during the mid-Tertiary.

Fins: Their colors are mainly olive and bronze or light brown with a white belly. The edges of the fins are usually darker on young Hammerhead sharks, but become lighter as they grow older.

Babies: 1 egg per birth

Natural enemies: people are enemies of hammerhead sharks.

Family: Sphyrnidae is a family of hammerhead sharks containing only two genera, one of which, Euphoria, contains only one species.
