Family:  Carcharhinidae (Requiem sharks)
Max. size:  204 cm TL (male/unsexed)
Environment:  demersal; freshwater; brackish; marine, amphidromous
Distribution:  Indo-West Pacific: Hooghly River, Ganges system, West Bengal, India, and likely from the vicinity of Karachi, Pakistan. Reported from Taiwan. (Ref. 5193)
Biology:  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.
IUCN Red List Status: Critically Endangered (CR); Date assessed: 22 January 2021 (A2cd; C2a(i)) Ref. (124695)
Threat to humans:  traumatogenic
