Elasmobranchii (sharks and rays) > Carcharhiniformes (Ground sharks) > Hemigaleidae (Weasel sharks)
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 ) .
More on author: Klunzinger .

Environment: milieu / climate zone / depth range / distribution range Ecology

Marine; demersal; depth range 1 - 130 m (Ref. 6871 ). Tropical; 41°N - 34°S, 12°E - 156°E (Ref. 6871 )

Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Indo-West Pacific: Red Sea and southeast Africa, including Persian Gulf (Ref. 68964 ) to Philippines, north to China, south to Australia.

Length at first maturity / Size / Weight / Age

Maturity: L m   ? , range 120 - ? cm
Max length : 240 cm TL male/unsexed; (Ref. 5578 ); common length : 200 cm TL male/unsexed; (Ref. 13567 )

Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 0; Anal spines : 0; Anal soft rays : 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 ).

Biology     Glossary (e.g. epibenthic)

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 Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

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 ).

Estimates based on models

Preferred temperature (Ref. 123201 ): 23.8 - 29, mean 27.9 °C (based on 2110 cells). Phylogenetic diversity index (Ref. 82804 ):  PD 50 = 1.0039   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.00363 (0.00147 - 0.00899), b=3.07 (2.86 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245 ). Trophic level (Ref. 69278 ):  4.3   ±0.3 se; based on diet studies. Resilience (Ref. 120179 ):  Very Low, minimum population doubling time more than 14 years (Fec=2). Fishing Vulnerability (Ref. 59153 ):  Very high vulnerability (90 of 100). Price category (Ref. 80766 ):   Unknown . Nutrients (Ref. 124155 ):  Calcium = 19.4 [3.2, 106.9] mg/100g; Iron = 0.636 [0.166, 1.913] mg/100g; Protein = 19.3 [17.2, 21.4] %; Omega3 = 0.101 [0.042, 0.245] g/100g; Selenium = 64.4 [18.5, 200.7] μg/100g; VitaminA = 13.4 [4.4, 42.6] μg/100g; Zinc = 0.614 [0.292, 1.120] mg/100g (wet weight);
