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.

Taille / Poids / Âge

Maturity: L_m ? range ? - ? cm
Max length : 300 cm TL mâle / non sexé; (Ref. 58048)

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).

Life cycle and mating behavior Maturities | Reproduction | Spawnings | Egg(s) | Fecundities | Larves

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).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00372 (0.00145 - 0.00950), b=3.09 (2.87 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.5 ±0.37 se; based on food items.

Résilience (Ref. 120179): Faible, temps minimum de doublement de population : 4,5 à 14 années (Fec assumed to be <100).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (90 of 100).

Catégorie de prix (Ref. 80766): Low.
