生物学特性     字汇 (例如 epibenthic)

Inhabits coastal waters and river mouths (Ref. 45255). Found on the continental shelf. Maximum disc width of about 180 cm. Ovoviviparous (Ref. 50449). Litters of a single pup; born at ca. 33 cm WD (Ref. 114953). Caught very rarely by the demersal tangle net fisheries operating in shelf waters. Utilized for its meat, cartilage and probably also its skin (Ref.58048).

栖息于沿岸水域与河口。 (参考文献 45255) 栖息于大陆架了。 大约 180 公分的最大体盘宽度。 卵胎生的.(参考文献 50449)

Life cycle and mating behavior 成熟度 | 繁殖 | 产卵场 | | 孕卵数 | 仔鱼

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).印度-西太平洋: 印度與澳洲北部.(有可能的在之間的區域中) 採集自恒河的河口了。 (參考文獻 33178)

Estimates based on models

Preferred temperature (Ref. 123201): 23.5 - 28.6, mean 27.3 °C (based on 1247 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00646 (0.00265 - 0.01571), b=3.06 (2.86 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
营养阶层 (Ref. 69278):  3.9   ±0.6 se; based on size and trophs of closest relatives
回复力 (Ref. 120179):  低的, 最小族群倍增时间4.5 - 14 年 (Assuming fecundity<100).
Fishing Vulnerability (Ref. 59153):  Very high vulnerability (90 of 100).
