Hemipristis elongata (Klunzinger, 1871) or Snaggletooth) is a species of weasel shark belonging to the family Hemigaleidae, the only extant member of the genus Hemipristis, widespread along the coasts of the Indo-Western Pacific.
This species is gray or bronze in color with no prominent markings and has sharp, serrated but slightly crooked teeth on the upper jaw and hooked teeth on the lower jaw. The body is tapered to allow the animal greater speed in the water.
Its length is up to 240 cm (7.87 ft). Despite only being vulnerable to extinction, this shark is very rarely seen.
The diet is quite varied, including bony fish, other sharks, rays, cephalopods and crabs.
Reproduction is a special type of viviparity, called placental viviparity, in which the shark carries its live young in a placenta-like structure, complete with an umbilical cord. The structure derives from the wall of the embryonic yolk sac which has fused with the uterine wall.
The species is present along the eastern coasts of Africa, from South Africa to Egypt, the southern and eastern coasts of Asia, from the Persian Gulf to China, and the coasts of Australia, at a depth not exceeding the 130 m . This shark can be found near the bottom of the water column of coastal areas, but can be found in continental and insular shelves.
