Indo-West Pacific: Red Sea, India (including Sri Lanka) to Indonesia, north to Japan (Ref. 114953). Australian and old records from the Mediterranean Sea and Suriname need confirmation.
印度-西太平洋: 紅海到新幾內亞,北至日本。 澳洲與來自地中海與蘇利南舊的記錄需要證實。

生物学特性     字汇 (例如 epibenthic)

Found inshore (Ref. 9909) and offshore (Ref. 58784). A carnivorous fish that feeds on large shellfishes (Ref. 58784). Ovoviviparous (Ref. 50449). Biology little known (Ref. 9909). Caught occasionally by demersal tangle net fisheries operating throughout the area. Utilized for its meat, find (both very high value), skin and cartilage (Ref.58048). Marketed fresh and probably dried-salted (Ref. 9909).

发现于岸边了。 (参考文献 9909) 卵胎生的.(参考文献 50449) 生物学特性知道的很少.(参考文献 9909) 可能在刺网与延绳钓捕获了。 (参考文献 9909) 在市场上销售生鲜地了与可能乾燥盐腌.(参考文献 9909)

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).印度-西太平洋: 紅海到新幾內亞,北至日本。 澳洲與來自地中海與蘇利南舊的記錄需要證實。

Estimates based on models

Preferred temperature (Ref. 115969): 24.8 - 29.1, mean 28.1 °C (based on 1958 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5156   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00355 (0.00136 - 0.00928), b=3.10 (2.87 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
营养阶层 (Ref. 69278):  3.5   ±0.37 se; based on food items.
回复力 (Ref. 120179):  低的, 最小族群倍增时间4.5 - 14 年 (Fec assumed to be <100).
脆弱性 (Ref. 59153):  Very high vulnerability (76 of 100) .
价格分类 (Ref. 80766):   Low.
