ກຸ່ມປາກະດູກອ່ອນ (ເຊັ່ນ: ປາສະຫລາມ, ປາຜາໄລ) (sharks and rays) > Carcharhiniformes (Ground sharks) > Hemigaleidae (Weasel sharks)
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).

Australian specimens with dark-tipped fins; tooth counts 28-34/43-54; total vertebral counts 111 to 118 (Ref. 13567). Indonesian, Singapore and Thailand specimens with light-tipped fins; tooth counts 25-32/37-43; total vertebral counts 137 to 150 (Ref. 13567). Grey-brown above, lighter below, dorsal fins with white tips and posterior margins, sometimes with spots on sides of body (Ref. 13567).

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).

Life cycle and mating behavior Maturities | ການສືບພັນ | Spawnings | Egg(s) | Fecundities | ຕົວອ່ອນ

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).
