Ecology Summary - Gymnothorax castaneus

Taal:

Belangrijkste Ref.	Grove, J.S. and R.J. Lavenberg, 1997
Opmerkingen	Lives in rocky, boulder strewn areas and walls. Lurks in holes, crevices and dark recesses during day; forage in the open at night. Constantly opens and closes its mouth--an action required for respiration, not a threat (Ref. 5227). May occasionally wander into open sandy areas about 10-20 m from cover. Feeds mainly on crustaceans and fishes and are highly responsive to stimuli emanating from wounded or distressed prey at distances exceeding 20 m (Ref. 28023). Most often seen with their head protruding from crevices during the day. Are known to wander forth to attack their prey at daytime. The prey need not be small or injured to elicit an attack . Being a large and aggressive moray, it presents a danger to lobster divers who enter caves or crevices (Ref. 28023).
