生态学
海洋 深海底的; 深度上下限 71 - 766 m (Ref. 10004). 深水域; 22°N - 10°S
Indo-West Pacific: widely distributed but with spotty records from Tanzania, the Gulf of Aden, India (Gulf of Mannar, Bay of Bengal), Andaman Islands, Viet Nam, and the Philippines. The immense range of this species is striking compared to the limited ranges of other members of the genus.
印度-西太平洋: 廣泛地分佈但是有點狀的來自坦尚尼亞,印度亞丁灣 (馬納爾灣 , 孟加拉灣) ,安達曼群島,越南與菲律賓的紀錄。 這一個有顯著的大範圍分佈相較於本屬的其他成員的有限制範圍。
Length at first maturity / 大小 / 重量 / 年龄
Maturity: Lm 15.5, range 15 - 16 cm
Max length : 23.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 244); 24.0 cm TL (female)
背棘 (总数) : 0; 臀棘: 0. Caudal fin without a rippled dorsal margin and ventral lobe but with a strong subterminal notch; vertebral axis of caudal fin little raised above body axis (Ref. 13566). Dark brown with blackish markings on dorsal fins (Ref. 13566).
尾鳍没有波浪状的上缘与腹叶但是有一个强的接近端位的凹槽; 尾鳍的椎骨轴在体轴上方稍微向上。 (参考文献 13566) 深褐色的在背鳍上有黑色的斑纹.(参考文献 13566)
Occurs over muddy bottoms, on the upper continental and insular slopes and outer shelves (Ref. 244). Feeds mainly on small bony fishes and crustaceans, with squid a lesser item in the diet (Ref. 244). One of the two smallest living sharks (Ref. 13566). Ovoviviparous (Ref. 50449), with 1 to 2 pups in a litter (Ref. 244).
在上层大陆斜坡与岛屿斜坡与外部的架上, 生活在泥底部之上。 (参考文献 244) 主要吃小的硬骨鱼类与甲壳动物, 较少猎捕乌贼。 (参考文献 244) 二个中的一个小的活鲨鱼.(参考文献 13566) 卵胎生的 (参考文献 50449), 1 到 2个幼胎一胎.(参考文献 244)
