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.

Size / Вес / Возраст

Maturity: L_m ? range ? - ? cm
Max length : 204 cm TL самец/пол неопределен; (Ref. 244)

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.

Estimates based on models

Preferred temperature (Ref. 115969): 24.6 - 28.1, mean 26.3 (based on 141 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00468 (0.00218 - 0.01003), b=3.09 (2.92 - 3.26), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.2 ±0.7 se; based on size and trophs of closest relatives

устойчивость к внешним воздействиям (Ref. 120179): очень низкий, минимальное время удвоения популяции более 14 лет (Assuming Fec<10).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (90 of 100).
