Most sharks are carnivorous although some eat plankton. There are eight orders of sharks, listed below in roughly their evolutionary relationship from more primitive to more modern species:

* Hexanchiformes: Examples from this group include the cow sharks, frilled shark and even a shark that looks on first inspection to be a marine snake.
* Squaliformes: Examples from this group include the bramble sharks, dogfish sharks and roughsharks, and prickly shark.
* Pristiophoriformes: These are the sawsharks, with an elongated, toothed snout that they use for slashing the fishes that they subsequently eat.
* Squatiniformes: Angel sharks.
* Heterodontiformes: They are commonly referred to as the bullhead or horn sharks.
* Orectolobiformes: They are commonly referred to as the carpet sharks, including zebra sharks, nurse sharks, wobbegongs and the largest of all fishes, the whale shark.
* Carcharhiniformes: They are commonly referred to as the groundsharks, and some of the species include the blue, tiger, bull, reef and oceanic whitetip sharks (collectively called the requiem sharks) along with the houndsharks, catsharks and hammerhead sharks. They are distinguished by an elongated snout and a nictitating membrane which protects the eyes during an attack.
* Lamniformes: They are commonly referred to as the mackerel sharks. They include the goblin shark, basking shark, megamouth shark, the thresher sharks, shortfin mako shark and great white shark. They are distinguished by their large jaws and ovoviviparous reproduction.
