توصيف مختصر
كليدهاي شناسايي | ريخت شناسي | ريخت ستجي بوسيله انداره گيري
Dark brown dorsally, slightly paler ventrally (Ref. 391).
A little-known inshore bottom shark of the continental and insular shelves. Well adapted to lie amongst coral reefs due to its tough skin (Ref. 391); depth data not available (Ref. 43278). Breeding and feeding habits are unknown. Presumably oviparous (Ref. 50449). Survives for many hours out of water (Ref. 391).
