Open encyclopedia reference
The blackspot shark (Carcharhinus sealei) is a small species of requiem shark in the family Carcharhinidae found in the tropical Indo-West Pacific Ocean between latitudes 24°N and 30°S, from the surface to a depth around 40 m (130 ft). Its length is a little under one meter (yard) and it is not considered to be dangerous to humans. It feeds mainly on fish, crustaceans, and squid. This shark is also caught in small-scale fisheries for human consumption.
Fossil teeth of the blackspot shark are known from the Late Miocene of Brunei, representing the oldest known record of the species.
