Indo-West Pacific: Hooghly River, Ganges system, West Bengal, India, and likely from the vicinity of Karachi, Pakistan. Reported from Taiwan. (Ref. 5193)

Tamaño / Peso / Age

Maturity: L_m ? range ? - ? cm
Max length : 204 cm TL macho / no sexado; (Ref. )

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. 123201): 24.6 - 28.1, mean 26.3 °C (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=0.00501 (0.00234 - 0.01075), b=3.08 (2.90 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

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

Resiliencia (Ref. 120179): Muy bajo, población duplicada en un tiempo mínimo superior a 14 años (Assuming Fec<10).

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