简单描述 型态特徵 | 形态测量图

背棘 (总数): 2; 背的软条 (总数): 0; 臀棘 0; 臀鳍软条: 0. The Zebra bullhead shark, Heterodontus zebra, has a large blunt head, low supra-orbital crest gradually sloping behind eyes, dorsal fin spines, anal fin, and zebra-pattern of dark, narrow vertical bands on a pale background (Ref. 9838; 6871). As characteristic of members of the family, caudal fin with a moderately long dorsal lobe and moderately long ventral lobe, the latter shorter than the dorsal lobe, vertebral axis raised into caudal-fin lobe (Ref.9838).
斑马鲶鱼鲨鱼 , Heterodontus 斑马 ,有一个大的钝头部, 低的上眼眶的冠在眼,背鳍棘,臀鳍与斑马条纹后面逐渐倾斜黑的, 狭窄的垂直条纹在灰白的背景上 (参考文献 9838; 6871)。 如该科的成员的特性, 尾鳍有一个中等长度的背部叶与中等长度的腹叶, 后者短于背部叶, 椎骨的轴进入尾鳍叶之内升起.(参考文献 9838)

生物学特性     字汇 (例如 epibenthic)

A common but little-known shark found on the continental and insular shelves in depths down to at least 50 m (Ref. 247, 11230) in the South China Sea, but deeper and in 150 - 200 meters off Western Australia (Ref. 43278). Probably feeds on bottom invertebrates and small fishes (Ref. 6871). Oviparous (Ref. 247).

一种常见的但是所知极少的鲨鱼发现于了,大陆棚与岛屿棚深度在南中国海向下至至少 50 公尺 (参考文献 247,11230), 但是比较深的与 150- 在西澳大利亚外 200 公尺处.(参考文献 43278) 可能吃底栖无脊椎动物与小鱼。 (参考文献 6871) 卵生的.(参考文献 247)

Life cycle and mating behavior 成熟度 | 繁殖 | 产卵场 | | 孕卵数 | 仔鱼

Oviparous, paired eggs are laid. Embryos feed solely on yolk (Ref. 50449). Distinct pairing with embrace (Ref. 205). Lays auger type eggs (about 12-18cm, 4.7-7 inches long) among rocks & kelp, often with more than female using same oviposition site, with as many eggs found in a single nest; female lay 2 eggs at a time, from spring to late summer in Japan, 6-12 times during a single spawning season. Eggs hatch in 1 year. Hatch at 18 cm (7 inches), max length at 1.2m (3.9 ft.). During courtship, male grasps pectoral fin of female & wraps posterior part of body under her so single clasper can be inserted into her cloaca. In several mating bouts observed, copulation lasted as long as 15 minutes (Ref. 12951).西太平洋: 日本到澳洲西北部 (參考文獻 6871) 與昆士蘭省。
