大小 / 重量 / 年齡
Maturity: Lm ? range ? - ? cm
Max length : 55.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 114953)
Occur on soft bottoms of the continental shelf (Ref. 7300, 75154). Feed on benthic fishes and crustaceans (Ref. 6871). Oviparous. Distinct pairing with embrace. Young may tend to follow large objects, such as their mother (Ref. 205). Eggs are oblong capsules with stiff pointed horns at the corners deposited in sandy or muddy flats (Ref. 205). Egg capsules are 4.4-6.3 cm long and 3.2-3.8 wide (Ref. 41308). Males reaches maturity at ca. 39 cm TL, females at ca. 42 cm TL; young hatch at ca. 10 cm TL (Ref. 114953).
生存在大陸棚的軟質底部上面。 (參考文獻 7300) 捕食底棲的魚與甲殼動物。 (參考文獻 6871) 卵生的。 明顯的成對出現。 幼魚可能傾向跟隨大的個體, 例如他們的母親.(參考文獻 205) 卵為長方形鞘囊具有僵硬的觸角沈積在沙灘或泥灘的角落.(參考文獻 205) 卵鞘是 4.4-6.3 公分長與 3.2-3.8 寬的.(參考文獻 41308)

Oviparous, paired eggs are laid. Embryos feed solely on yolk (Ref. 50449). Distinct pairing with embrace. Young may tend to follow large objects, such as their mother (Ref. 205).東印度洋: 澳洲的特有種。
