This large shovelnose ray is distinguished by the following characters: suboval disc, short and broadly rounded snout with nostrils partly covered with a large nasal curtain; sharp thorns present on mid-line of disc and shoulders; behind interorbital space is an ornate pattern of dark-edged bands with distinct triangular or diamond-shaped marking (Ref. 114953).
A benthic species and an active scavenger which will enter fish traps and often becoming ensnared by the disc (Ref. 6871). Found also on sandy bottoms and seagrass areas, often near rocky reefs (Ref. 12951). Mainly feeds on crabs and shrimps (Ref. 114953). Ovoviviparous with golden egg capsules, each with up to 3 embryos (Ref. 12951). Produces up to 2-3 pups. Length size seldom exceeds 110 cm TL; birth size at ca. 25 cm TL (Ref. 114953). The flesh is good to eat, although only a small quantity is sold in seafood outlets (Ref. 6871).
普遍的在海岸 (參考文獻 6871) 的附近, 在砂質底部與海草區域上, 時常鄰近岩礁.(參考文獻 12951) 分佈自潮間帶到 180 公尺。 (參考文獻 12951) 卵胎生的有金色的卵鞘，每個具有向上到 3個胚胎.(參考文獻 12951) 肉是好吃, 雖然只有小的量在海鮮出口被賣。 (參考文獻 6871)
Life cycle and mating behavior
成熟度 | 繁殖 | 產卵場 | 卵 | 孕卵數 | 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).東印度洋: 澳洲的特有種。
