简单描述
型态特徵 | 形态测量图
This species is distinguished from its congeners in Bathyraja in having a whitish area along the inner margin of eyes; dorsal side of disc with minute fine prickles; pointed clasper with a pseudosiphon-like groove; dense, minute prickles covering smaller egg capsule (Ref. 75535).
Juveniles feed mainly on amphipods, adults feed on crabs and fish (Ref. 27640). 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 7.6 cm long and 5.5 cm wide (Ref. 41249).
稚鱼主要捕食片脚类动物, 成鱼吃螃蟹与鱼。 (参考文献 27640) 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 7.6 公分长与 5.5 公分宽的.(参考文献 41249)
Life cycle and mating behavior
成熟度 | 繁殖 | 产卵场 | 卵 | 孕卵数 | 仔鱼
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).北太平洋: 鄂霍次克海外海的日本網走到堪察加半島與白令海。
