Etymology: Hemipristis: hemi-, from hemisys (Gr.), half; pristis, from pristes (Gr.), sawyer (but here meaning saw), allusion not explained, possibly referring to how marginal serrations of teeth of H. serra (type species, a fossil) do not extend over the entire length of each tooth. (See ETYFish); elongata: Latin for prolonged, referring to its long and slim body. (See ETYFish).

Short description Claves de identificación | Morfología | Morfometría

Espinas dorsales (total) : 0; Espinas anales: 0. A slender weasel shark with a long, broadly rounded snout, large curved, saw-edged teeth in the upper jaw, and hooked lower teeth protruding from mouth; gill slits long; fins strongly curved (Ref. 5578). Light grey or bronzy with no prominent markings (Ref. 5578).

A coastal species, found inshore and offshore on the continental and insular shelves (Ref. 244). Feeds on sharks, rays and bony fishes (Ref. 244); also cephalopods (Ref. 13567). Viviparous (Ref. 50449). Thought to be potentially dangerous because of its large, fearsome teeth and shallow-water habitat, but has not been recorded in an attack on people (Ref. 244). Caught regularly by inshore gillnet, bottom trawl (occasionally) and longline fisheries (Ref.58048). Regularly taken in artisanal fisheries (Ref. 13567). Utilized fresh for human consumption, liver processed for vitamins, fins used in the oriental shark fin trade, and by-products processed into fishmeal (Ref. 244). Most adults below 200 cm (Ref. 30573).

Life cycle and mating behavior Maturities | Reproducción | Spawnings | Egg(s) | Fecundities | Larva

Viviparous, with 2 to 11 young in a litter (Ref. 6871) after a gestation period of 7-8 months; possibly reproduces in alternate years (Ref.58048). Size at birth about 45-52 cm TL (Ref. 13567, Ref.58048). Distinct pairing with embrace (Ref. 205).
