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.

Biología     Glosario (por ej. 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.
