Ecology of Gymnothorax flavimarginatus
Main Ref. Myers, R.F., 1991
Remarks Inhabits a variety of zones ranging from reef flats and protected shorelines to seaward reefs. Along drop-offs (Ref. 48635). Benthic (Ref. 58302). Feeds on cephalopods (Ref. 30573), fishes, and crustaceans. Most often appears on the reef after a fish has been speared during daylight. The regularity and promptness of such appearances make it clear that G. flavimarginatus is especially sensitive to stimuli emanating from an injured or stressed fish (Ref. 13550). Carnivore (Ref. 57615). Also in Ref. 9137, 58534.
