It contains over half of the species in its family, with 36-38 extant and eight extinct species currently recognized.[1] The genus was established by Blainville in 1816.[2] Within the family Carcharhinidae, the genus Carcharhinus serves as the type genus.[1]

Biology and range

These species begin appearing in the fossil record from that time.[3] Carcharhinus teeth are highly species-specific in morphology but are highly variable within and among species.[3] The teeth also vary within a single jaw, requiring careful study for species assignment.[3] The genus is found in marine, brackish, and freshwater environments.[2]

It belongs to the order Carcharhiniformes and class Elasmobranchii.[2] Based on fossil tooth evidence, most currently living Carcharhinus species had already appeared by the start of the Early Miocene.[3]

What the specialist sources record

A 1994 study by Naylor notes that identifying isolated Carcharhinus teeth to species is relevant for tracking phyletic change through the fossil record.[3] A 2024 review by Höltke discusses the paleobiology of Neogene sharks and the fossil records of extant shark species.[3] The World Register of Marine Species (AphiaID 105719) accepts Carcharhinus Blainville, 1816 as a valid genus within the family Carcharhinidae.[2]
