морской; пресноводный; солоноватоводный демерсальный; мигрирует в реке (Ref. 51243). Tropical
Asia: Gangetic river system. Possibly in the Bay of Bengal and the Fly river system in New Guinea. Status is uncertain, close to Himantura chaophraya. Validity of this species questioned in Compagno's 1999 checklist (Ref. 35766).

Life cycle and mating behavior
Maturities | размножение | Spawnings | Egg(s) | Fecundities | личинки
Exhibit ovoviparity (aplacental viviparity), with embryos feeding initially on yolk, then receiving additional nourishment from the mother by indirect absorption of uterine fluid enriched with mucus, fat or protein through specialised structures (Ref. 50449). Distinct pairing with embrace (Ref. 205).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00832 (0.00366 - 0.01891), b=3.10 (2.90 - 3.30), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.6 ±0.5 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).
