Open encyclopedia reference
The smoothtooth blacktip shark (Carcharhinus leiodon) is a species of requiem shark in the family Carcharhinidae. It is known only from the type specimen caught from the Gulf of Aden, off eastern Yemen, and a handful of additional specimens caught from the Persian Gulf, off Kuwait. Reaching 1.3 m (4.3 ft) in length, this species has a stocky greenish-colored body, a short snout, and black-tipped fins. It can be distinguished from similar species by its teeth, which are narrow, erect, and smooth-edged.
Little is known of the smoothtooth blacktip shark's natural history; it likely inhabits shallow waters and feeds on small bony fishes. It is presumably viviparous like other members of its family. The International Union for Conservation of Nature last assessed this species as endangered. Although more specimens have since been discovered, the conservation status of this species remains precarious due to heavy fishing and habitat degradation within its range.
