Etymology: Iago: Name of villain in Shakespeare’s Othello , because members of this genus have been a “troublemaker for systematists and hence a kind of villain”. ( See ETYFish ) ;   omanensis: -ensis , Latin suffix denoting place: Gulf of Oman, type locality. ( See ETYFish ) .

Environment: milieu / climate zone / depth range / distribution range Ecology

Marine; bathydemersal; depth range 110 - 2195 m (Ref. 244 ). Deep-water; 30°N - 10°N

Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

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.

Length at first maturity / Size / Weight / Age

Maturity: L m 55.7   range ? - ? cm
Max length : 37.0 cm TL male/unsexed; (Ref. 244 ); 58.0 cm TL (female)

Short description Morphology | Morphometrics

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

Biology     Glossary (e.g. epibenthic)

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.

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Viviparous, placental (Ref. 50449 ). Distinct pairing with embrace (Ref. 205 ).

Estimates based on models

Preferred temperature (Ref. 123201 ): 10 - 21.7, mean 14.6 °C (based on 100 cells). Phylogenetic diversity index (Ref. 82804 ):  PD 50 = 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 ). Trophic level (Ref. 69278 ):  4.2   ±0.3 se; based on diet studies. Resilience (Ref. 120179 ):  Very Low, minimum population doubling time more than 14 years (K=0.48; Fec=2). Fishing Vulnerability (Ref. 59153 ):  Moderate vulnerability (43 of 100). Price category (Ref. 80766 ):   High .
