Maturity: Lm ? range ? - ? cm
Max length : 60.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. )
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 6.0 cm long and 3.4 cm wide (Ref. 41249). Frequently taken in commercial bottom hauls but not much utilized because of its small size (Ref. 5159).
卵生的。 明显的成对出现。 幼鱼可能倾向跟随大的个体, 例如他们的母亲.(参考文献 205) 卵为长方形鞘囊具有僵硬的触角沈积在沙滩或泥滩的角落.(参考文献 205) 卵鞘是 6.0 公分长与 3.4 公分宽的.(参考文献 41249) 时常采自了商业的底拖网但是不多利用由于它的体型小.(参考文献 5159)
Life cycle and mating behavior

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). Eggs have horn-like projections on the shell (Ref. 205).南極海: 克魁嶺高原的特有種。
