The classification of sharks is difficult. That’s true in particular for the species of requiem sharks that all looks quite alike. The Coates’s shark (Carcharhinus coatesi), named after the ichthyologist George Coates, was discovered in 1939, but had been equated with the Blackspot shark (Carcharhinus sealei) since 1982. As recently as 2012 they have been adjudged as 2 different species, after all.

The Whitecheek shark (Carcharhinus dussumieri) is a different species, too, but is synonymous with Coates’s shark in the source of my picture, that’s why it could be false.

The Coates’s shark is a small shark. Born alive (viviparous) at a length of 15 to 16 in – 38 to 40 cm -, it grows to at most 2.89 ft – 88 cm. It inhabits the surface to a depth of 404 ft – 123 m – off northern Australia.
