The school shark, tope shark, soupfin shark or snapper shark, Galeorhinus galeus, is a hound shark of the family Triakidae, the only member of the genus Galeorhinus, found worldwide in subtropical seas at depths of up to 550 metres (1,800 ft). It grows to 2 metres (6 ft 7 in) long.
Reproduction is ovoviviparous.
In 2010, Greenpeace International added the school shark to its seafood red list. "The Greenpeace International seafood red list is a list of fish that are commonly sold in supermarkets around the world, and which have a very high risk of being sourced from unsustainable fisheries."
The meat of the school shark is consumed in Spanish cuisine where it is usually known as cazón. Among recipes are the traditional cazón en adobo in the mainland, and tollos in the Canary Islands. In Mexican cuisine, the term cazón refers to other species, and is prepared similarly.
