Шаблон:Short description Шаблон:For Шаблон:Automatic taxobox Carcharias is a genus of mackerel sharks belonging to the family Odontaspididae (sand sharks). Once bearing many prehistoric species, all have gone extinct with the exception of the critically endangered sand tiger shark.

Description

Carcharias are Шаблон:Cvt long on average. The maximum weight of the shark is Шаблон:Cvt.[1]

Differentiating species of sharks is usually done by locating and measuring their fins. The tail is one third of the entire body size. The second dorsal fin and the anal fin of Carcharias are very large and about equal in size. The pectoral fins are triangular and only slightly larger than the dorsal fins. The teeth are very long and narrow with sharp points, and smooth with no ridges.[2]

Diet

Carcharias species are generalist predators that hunt bony fish, small sharks, rays, squids, crabs and lobsters.[3] Шаблон:Portal

Habitat

Sand tiger sharks are found in the Pacific, Atlantic and Indian oceans. They live in water depths ranging from Шаблон:Cvt, and are commonly found in sandy surf zones.[3]

Species

With the Greek name Carcharias literally translating to “shark”, many presently extant species have been placed into this genus before being moved to different genera and orders.

Extinct species

Extinct species within this genus lived from the Cretaceous period to the Quaternary period (from 99.7 to 0.012 Ma). Fossils have been found all over the world, especially in the Miocene and Oligocene sediments of Europe, the United States and Australia, in the Eocene of Egypt, Europe and the United States, as well as in the Cretaceous of Australia, Canada, the United States, Europe and Africa.[12] Species from the fossil record include:[12]
