生態学
海 底生の; 深さの範囲 10 - 140 m (Ref. 6871). Deep-water; 8°S - 30°S, 130°E - 155°E (Ref. 114953)
Western Pacific: Australia and Papua New Guinea. This species has been misidentified by most ichthyologists as a color form of Himantura uarnak (Ref. 6871). Also Ref. 114953.
サイズ / 重さ / 年齢
Maturity: Lm ? range ? - ? cm
Max length : 86.0 cm WD オス/雌雄の選別がない; (Ref. 58048)
Demersal on soft bottoms on the continental shelf at depths of 10-140m (Ref.58048). Juveniles (20-22 cm WD) are free swimming. Feeds on prawns, small fishes and crustaceans (Ref. 9840). Ovoviviparous (Ref. 50449). Common by-catch of bottom trawl and beach seine fisheries in the Arafura Sea. Utilized for its meat, skin (high value) and cartilage (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). Distinct pairing with embrace (Ref. 205). Born at 20-22 cm WD (Ref.58048).
