Ecology Summary - Gymnothorax javanicus

Language:

Main Ref.	Hiatt, R.W. and D.W. Strasburg, 1960
Remarks	Inhabits coral reefs (Ref. 58534); lagoon and seaward reefs. Commonly seen species along deep drop-offs and slopes in Indonesian waters (Ref. 48635). Benthic (Ref. 58302). Juveniles more secretive and occur on intertidal reef flats (Ref. 37816). It feeds primarily on fishes and occasionally on crustaceans; also on benthic invertebrates (Ref. 275). This is the largest Indo-Pacific moray eel (Ref. 30404), perhaps reaching 3 m in length. Because of its position at the top of the reef's food chain it is often ciguatoxic. Attacks humans when provoked (Ref. 3132).
