This frightening shark has the head of a lizard and the body of a large eel. Unlike other sharks, its gills are around its throats. Each pair of gills has a red fringe on its edge which is the reason for its name. Frilled sharks have 300 teeth aligned in twenty-five rows. They can swallow their prey whole due to their large mouths. They feed on octopus, squid, bony fish and other smaller species of sharks.
