簡単な記述
形態学 | 形態計測学
A small devilray with a short head bearing short head fins; dorsal fin white-tipped, and pectoral fins with slightly curved tips; upper surface with no denticles and tail shorter than disc, with no spine (Ref. 5578). Dark brown above, white below (Ref. 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).
Life cycle and mating behavior
成熟 | 繁殖 | 放精 | 卵 | 生産力 | 幼生
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).
