Bottom-dweller that feeds on invertebrates and bony fish. 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 4.8-6.6 cm long and 2.9-3.7 cm wide (Ref. 41249, 41253, 41298). Depth range given by H. Ishihara (pers.comm. 07/07).
底栖鱼类捕食无脊椎动物与硬骨鱼。 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 4.8-6.6 公分长与 2.9-3.7 公分宽的.(参考文献 41249,41253,41298)
Oviparous, paired eggs are laid mainly at night (Ref. 44760). Batches of eggs are laid in three to six-day interval on sand bottom. Embryos feed solely on yolk (Ref. 50449). Distinct pairing with embrace. Young may tend to follow large objects, such as their mother (Ref. 205).西太平洋: 日本，韓國與台灣 (參考文獻 8630) 到中西太平洋.(參考文獻 9908)
