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).
亞洲: 恆河流域。 可能地在新幾內亞的孟加拉灣與飛河系統。 狀態不確定, 接近 Himantura chaophraya. 這種的有效性在 Compagno 1999 名錄懷疑了。 (參考文獻 35766)

Life cycle and mating behavior Maturities | 繁殖 | Spawnings | Egg(s) | Fecundities | 仔魚

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).亞洲: 恆河流域。 可能地在新幾內亞的孟加拉灣與飛河系統。 狀態不確定, 接近 Himantura chaophraya. 這種的有效性在 Compagno 1999 名錄懷疑了。 (參考文獻 35766)

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 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).
營養階層 (Ref. 69278):  3.6   ±0.5 se; based on size and trophs of closest relatives
回復力 (Ref. 120179):  非常低的, 最小族群倍增時間超過14 年 (Assuming Fec<10).
Fishing Vulnerability (Ref. 59153):  Very high vulnerability (90 of 100).
價格種類 (Ref. 80766):   Low.
