简单描述
型态特徵 | 形态测量图
背棘 (总数): 0; 背的软条 (总数): 0; 臀棘 0; 臀鳍软条: 0. Five to six dermal flaps below and in front of eyes; back with light areas between dark saddles marked with broad reticulated dark lines (Ref. 13577). Caudal fin with its upper lobe hardly elevated above the body axis, with a strong terminal lobe and subterminal notch but no ventral lobe (Ref. 13577).
在眼下面与前面的五到六个皮芽; 背面有在黑的鞍状标记之间的淡色区域有宽的网状黑色线条.(参考文献 13577) 尾鳍上叶并不高的上方体轴, 具有一个强韧的端叶与接近端位的凹槽但是没有腹的叶.(参考文献 13577)
A little-known bottom shark found inshore (Ref. 247); usually in sand or sandy mud bottoms (Ref. 11230); also on rocky and coral reefs (Ref. 43278). Nocturnal in habits (Ref. 247). Feeds on fish and presumably bottom invertebrates (Ref. 247), including lizardfishes, cutlassfish, horse mackerel and other jacks, goatfishes, groupers, tilefishes, sea robins, whiting, parrotfishes, sea bream, croakers, also skates, shark egg cases, cephalopods, and shrimp (Ref. 43278). Ovoviviparous (Ref. 43278, 50449), with up to 20 young in a litter (Ref. 247). Wobbegongs should be regarded as potentially dangerous because of its formidable dentition (Ref. 247, 13577). Used for human consumption (Ref. 247). Kept in aquaria in Japan and the United States (Ref. 43278).
所知极少的底栖鲨鱼发现沿海地区;(参考文献 247) 通常在沙子或沙泥底;(参考文献 11230) 也在岩石与珊瑚礁上.(参考文献 43278) 夜行性.(参考文献 247) 捕食鱼类, 与可能底栖无脊椎动物.(参考文献 247) 卵胎生的 (参考文献 50449), 多达 20 幼鱼在一胎.(参考文献 247)。 须鲨应该被视为可能危险由于它的强大生齿.(参考文献 247,13577) 供人类消费使用.(参考文献 247) 在日本与美国保存于水族馆了。 (参考文献 43278)
