生物學特性     字彙 (例如 epibenthic)

A little-known reef shark found in shallow water on the continental and insular shelves, but may range in deeper water (Ref. 244). Feeds on small fishes and crabs (Ref. 244). Viviparous (Ref. 50449). Rather skittish and timid when approached (Ref. 244). Probably harmless or minimally hazardous to people (Ref. 244). Utilized for human consumption (Ref. 9997).
