Regulations: | Ref:
Uses: no uses
Comments: Outside distributional range (Ref. 125614). Reported as ?Carcharinus gangeticus, recorded in Lake Naujan, Mindoro (Ref. 5517); as ?Carcharias gangeticus; records from Manila Bay, Cebu Agusan River & Saug River (Davao), Jolo Is & Sitankai (Sulu), Lake Naujan (Mindoro) (Ref. 280). Nominal records of Glyphis gangeticus from the Philippines cannot be confirmed; these may be based in whole or in part on Carcharhinus leucas. In the Western Pacific, three other Glyphis species are known and maybe wider-ranging (Ref. 47737). Also in Ref. 47930.

Biologi     Ordlista (t.ex. epibenthic)

Biology poorly known. But its minute eyes suggest that it may be adapted to turbid water with poor visibility, as in large tropical rivers and muddy estuaries. Newborn specimens are from 56 to 61 cm long. Viviparous (Ref. 50449). Its notoriety may have stemmed from its widespread confusion with C. leucas. But this species is potentially dangerous as well because of its size and large teeth, though its reputation as a man-eater is still unproven.

Viviparous, placental (Ref. 50449). Distinct pairing with embrace (Ref. 205).
