Βιολογία     Γλωσσάρι (π.χ. epibenthic)

A tropical inshore shark found on sand, rubble, or coral bottoms of the continental and insular shelves (Ref. 247). Recorded to have entered freshwater (Ref. 4735). Rather sluggish at least during the day (Ref. 247). Probably nocturnal, feeds mainly on mollusks, but also small bony fishes (Ref. 9993). Also known to eat crustaceans (crabs and shrimps) and sea snakes (Ref. 43278). Oviparous (Ref. 43278, 50449). Slow-swimming and able to squirm into narrow cracks, crevices and channel in reefs while searching for food (Ref. 247). Readily kept in captivity (Ref. 247). May bite when provoked (Ref. 247). Utilized fresh and dried-salted for human consumption and also for fishmeal; livers processed for vitamins; fins dried for the oriental sharkfin trade; offal utilized for fishmeal (Ref. 247). Possibly reaching 354 cm TL (Ref. 9993, 47613). Caught in drift net intended for sharks (Ref. 47736). Reported from freshwater in the Philippines but needs to be confirmed (Ref. 43278).
