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).

marino batidemersale; distribuzione batimetrica 110 - 2195 m (Ref. 244). Deep-water; 30°N - 10°N
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.

Short description
Chiavi di identificazione | Morfologia | Morfometria
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.
Viviparous, placental (Ref. 50449). Distinct pairing with embrace (Ref. 205).
