Lamniformes is an order of sharks, also known as mackerel sharks (which may also be used to refer to the sub-group of Lamniformes, Lamnidae). It includes some of the most familiar species of sharks, such as the great white shark, and some extremely rare types, such as the megamouth shark.
Members of the order are distinguished by possessing two dorsal fins, an anal fin, five gill slits, eyes without nictitating membranes, and a mouth extending behind the eyes.
