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.
Grootte / Gewicht / Leeftijd
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).
Levenscyclus en paargedrag Maturiteit | Voortplanting | Paaien | Eieren | Fecunditeit | Larven
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).

Estimates based on models
Preferred temperature (Ref. 123201): 24.8 - 29.1, mean 28.1 °C (based on 1958 cells).
Fylogenetische diversiteitsindex (Ref. 82804): PD50 = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00363 (0.00143 - 0.00920), b=3.09 (2.87 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trofisch niveau (Ref. 69278): 3.5 ±0.37 se; based on food items.
Weerstandsvermogen (Ref. 120179): laag, minimale populatieverdubbelingstijd 4,5-14 jaar (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153): Very high vulnerability (90 of 100).
