Carcharias is a genus of Sand Tiger Sharks belonging to the family Odontaspididae.
Carcharias are 2.5m long on average. The maximum weight of the shark is 158.8 kg.
Differentiating different species of sharks is usually done by locating and measuring their fins. The second dorsal fin and the anal fin of Carcharias are very large. In fact, they are 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. The teeth are smooth with no ridges. The tail is one third of the entire body size.
Carcharias species hunt bony fish, small sharks, rays, squids, crabs, and lobsters.
Sand Tiger Sharks live in water depths ranging from 0 to 190 meters. They are found in the Pacific, Atlantic, and Indian oceans. They are commonly found in surf zones.
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, United States and Australia, in the Eocene of Egypt, Europe and United States, as well as in the Cretaceous of Australia, Canada, United States, Europe and Africa. Extinct species include:
