Ecology Summary - Drepane longimana

Language:

Main Ref.	Heemstra, P.C., 1997
Remarks	Demersal (Ref. 122479). Found inshore, on sand or mud bottoms, reefs, estuaries and harbours (Ref. 9800). Also found on rocky substrates (Ref. 107708). Maximum depth for this species is less than 50 m. Feeds on benthic invertebrates. Breeds close inshore during spring (Ref. 9800). Dwells in reefs and shallow coastal bays. Its tolerance to fluctuations in salinity allows it to enter estuaries. Feeds on small crabs, shrimp and marine worms (Ref. 9773).
