Western Indian Ocean: Red Sea, Gulf of Aqaba (Ref. 9942) and Gulf of Oman to Pakistan and southwestern India. A low-finned, somewhat short-headed Iago is largely sympatric with Iago omanensis at least off southwestern India, and in the Bay of Bengal there is possibly a dwarf, omanensis-like Iago that may or may not be distinct.

Description synthétique Clés d'identification | Morphologie | Morphométrie

Brown or grey dorsally, lighter below; dorsal and caudal fins may have darker tips and leading edges (Ref. 5485).

Found on the continental shelf and slope. Water temperature: 16-25°C. Oxygen level: 0.2-2.4 ppm. Feeds on bony fishes (mostly lanternfishes) and cephalopods. Sexual dimorphism by size exists. Viviparous (with a yolk-sac placenta), with probably 2 to 10 young in a litter. Utilized fresh for human consumption.

Estimates based on models

Preferred temperature (Ref. 123201): 10 - 21.7, mean 14.6 °C (based on 100 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00427 (0.00183 - 0.00992), b=3.04 (2.83 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 4.2 ±0.3 se; based on diet studies.

Résilience (Ref. 120179): Très faible, temps minimum de doublement de population supérieur à 14 ans (K=0.48; Fec=2).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (43 of 100).

Catégorie de prix (Ref. 80766): High.
