Biologie     Verklarende woordenlijst (bv. epibenthic)

A little known inshore and offshore shark found on continental and insular shelves (Ref. 244). Found to depths of at least 36 m (Ref. 9997). Probably feeds on fishes, cephalopods, and crustaceans (Ref. 6871). Viviparous (Ref. 50449). Commonly caught by inshore demersal gillnet fisheries, especially off Java (Ref.58048). Utilized fresh and probably dried salted for human consumption (Ref. 244). Also used for fishmeal (Ref. 9997) and fins (Ref.58048). Minimum depth from Ref. 58018.
