简单描述
型态特徵 | 形态测量图
Brown dorsally, mottled with white and black spots, and a large dark blotch on each wing; white ventrally (Ref. 26346).
背部褐色的, 在每个翼上具有白色与黑色的斑点 , 与一个大的黑色斑块色斑; 腹侧白色的.(参考文献 26346)
Inhabit the continental shelf and upper slope (Ref. 26346); usually in coastal waters (Ref. 9258). Found partially buried in sand (Ref. 26346). Feed on fish, shellfish, crabs, and worms (Ref. 114953, 26346). 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 10.2-12.7 cm long and 6.3-8.3 cm wide (Ref. 41249, 41308).
栖息于大陆架与上层斜坡;(参考文献 26346) 通常在沿岸水域。 (参考文献 9258) 发现身体的一部分埋藏在沙子中.(参考文献 26346) 捕食鱼，贝，螃蟹，与蠕虫。 (参考文献 26346) 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 10.2-12.7 公分长与 6.3-8.3 公分宽的.(参考文献 41249,41308)
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). Young hatching at about 18-20 cm (Ref. 26346). Distinct pairing with embrace. Young may tend to follow large objects, such as their mother (Ref. 205).西南太平洋: 紐西蘭的特有種。
