生態學
海洋 居於水底的; 深度上下限 10 - 140 m (Ref. 6871). 深水域; 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.
印度-西太平洋: 澳洲北部與新幾內亞, 包括阿拉弗拉海與帝汶海。 發生印尼外海未知。 這種被大多數的魚類學者誤鑑為一個色彩形式的 Himantura uarnak 。 (參考文獻 6871)
大小 / 重量 / 年齡
Maturity: Lm ? range ? - ? cm
Max length : 86.0 cm WD 雄魚/尚未辨別雌雄; (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).
棲息於大陸棚了。 (參考文獻 9840) 稚魚 (20-22 公分 WD) 是游離於水中。 吃蝦，小魚與甲殼動物。 (參考文獻 9840) 卵胎生的.(參考文獻 50449)
Life cycle and mating behavior
Maturities | 繁殖 | Spawnings | Egg(s) | Fecundities | 仔魚
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).印度-西太平洋: 澳洲北部與新幾內亞, 包括阿拉弗拉海與帝汶海。 發生印尼外海未知。 這種被大多數的魚類學者誤鑑為一個色彩形式的 Himantura uarnak 。 (參考文獻 6871)

Estimates based on models
Preferred temperature (Ref.
123201): 25.5 - 28.2, mean 27.2 °C (based on 255 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01622 (0.00606 - 0.04338), b=3.00 (2.77 - 3.23), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
