Carcharodon is a genus of large lamniform sharks within the family Lamnidae, currently represented by the extant species Carcharodon carcharias (the white shark) and several extinct species known from the fossil record. Members of this genus are characterized by robust, conical teeth with serrated cutting edges, a fusiform body adapted for high-speed predation, regional endothermy enabling elevated body temperatures relative to ambient seawater, and an apex trophic position in marine food webs. Paleobiological and molecular data indicate a complex evolutionary history distinct from the extinct megatooth sharks (genus Otodus), with Carcharodon exhibiting specialized adaptations for macropredatory feeding on marine mammals and large fishes.
