Etymology: Hemigaleus: hemi-, from hemisys (Gr.), half, referring to similarity to and/or close affinity with Galeus (now in Pentanchidae) (See ETYFish); microstoma: micro-, from mikros (Gr.), small; stoma (Gr.), mouth, referring to very short arched mouth compared with Chaenogaleus macrostoma, its presumed congener at the time (See ETYFish).

Body shape (shape guide): elongated.
A small, relatively common inshore and offshore shark of tropical continental seas (Ref. 13567). Feeds mainly on cephalopods, particularly octopi (Ref. 13567) but also takes crustaceans and cephalopods (Ref. 244). Viviparous (Ref. 50449). Taken regularly in inshore artisanal fisheries (Ref.244), commonly caught by inshore gillnet, bottom trawl and, to a lesser extent, longline fisheries. Utilized for human consumption (Ref. 244). Offal used for fishmeal (Ref. 244).
ライフサイクルと交尾行動 成熟 | 繁殖 | 放精 | 卵 | 生産力 | 幼生
Viviparous, with a yolk-sac placenta; 4 to 14 fetuses in a litter (Ref. 13567); 2-4 pups after a gestation period of about 6 months; born at about 45-47 cm TL (Ref. 58048). Size of full-term fetuses (detached umbilical cords and placentae) ranges from 23.7 to 25.6 cm (Ref. 244). Distinct pairing with embrace (Ref. 205).
