Holotype taken from a depth between 405-420 m (Ref. 26282). 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 6.7 cm long and 4.7 cm wide (Ref. 41249).
Holotype 取自了在 405-420 公尺之间的深度。 (参考文献 26282) 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 6.7 公分长与 4.7 公分宽的.(参考文献 41249)
