生物學特性     字彙 (例如 epibenthic)

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).

所知極少的底棲鯊魚發現沿海地區;(參考文獻 247) 通常在沙子或沙泥底;(參考文獻 11230) 也在岩石與珊瑚礁上.(參考文獻 43278) 夜行性.(參考文獻 247) 吃魚, 與可能底棲無脊椎動物.(參考文獻 247) 卵胎生的 (參考文獻 50449), 多達 20 幼魚在一胎.(參考文獻 247)。 鬚鯊應該被視為可能危險由於它的強大生齒.(參考文獻 247,13577) 供人類消費使用.(參考文獻 247) 在日本與美國保存於水族館了。 (參考文獻 43278)
