一種小的魔鬼魟具有一個生長著短的頭鰭的短的頭部; 背鰭尖端白色的, 而且胸鰭有略微彎曲的頂端; 上表皮沒有細齒而且尾部短於體盤, 沒有棘.(參考文獻 5578) 上方深褐色的, 腹面白色的.(參考文獻 5578)
Found in coastal and oceanic waters (Ref. 5578). Feeds on plankton (Ref. 30573). Ovoviviparous (Ref. 50449). Generally found in schools, leaping out of the water (Ref. 11228). Caught rarely in the tuna gillnet fisheries. Utilized for its gill filter plates (high value), meat, cartilage and skin (Ref.58048).

Exhibit ovoviparity (aplacental viviparity), with embryos feeding initially on yolk, then receiving additional nourishment from the mother by indirect absorption of uterine fluid enriched with mucus, fat or protein through specialised structures (Ref. 50449). Probably giving birth to only one pup; born at ~31 cm WD (Ref.58048).印度-西太平洋: 非洲東岸到印尼。
