生態學
海洋 深海底的; 深度上下限 110 - 2195 m (Ref. 244). 深水域; 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.
西印度洋: 紅海，阿卡巴灣 (參考文獻 9942) 與阿曼灣到巴基斯坦與印度西南部。 一個鰭低, 頭部略短 Iago 主要地與 大眼前鰭皺唇鯊〔Iago omanensis〕 至少印度西南部外海重疊分佈, 而且在孟加拉灣可能地有矮小, omanensis-例如 Iago 哪一可能或者可能不是明顯的。

Max length : 37.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 244); 58.0 cm TL (female)
Brown or grey dorsally, lighter below; dorsal and caudal fins may have darker tips and leading edges (Ref. 5485).
褐色或灰色的背面, 腹面顏色較淡; 背鰭與尾鰭鰭可能有較深色的頂端與前緣。 (參考文獻 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.
棲息於大陸棚及大陸坡了。 水溫: 16-25個 ° C. 含氧量: 0.2-2.4 ppm。 吃硬骨魚類 (大部份燈籠魚) 與頭足類動物。 性的同種二形依大小存在。 胎生的 (具有一個卵黃囊胎盤), 可能 2 到 10 幼魚在一胎。 生鮮使用供人類消費。
