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).

背棘 (總數) : 0; 臀棘: 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).
Body shape (shape guide): elongated.

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).
一個沿岸魚種, 發現岸邊與外海的在大陸棚與島嶼棚上.(參考文獻 244) 吃鯊魚，魟與硬骨魚類;(參考文獻 244) 也捕食頭足類.(參考文獻 13567) 胎生的.(參考文獻 50449) 被認為可能危險由於它的大又嚇人的齒與淺水的棲息地了, 但是沒有在一個對人的攻擊中被記錄.(參考文獻 244) 經常地被漁民捕獲.(參考文獻 13567) 生鮮使用供人類消費, 肝臟加工成維他命了, 鰭被用於東方的鯊魚鰭貿易了，而且副產物加工成魚粉了。 (參考文獻 244) 大多數的成魚小於 200 公分.(參考文獻 30573)
