Ecology of Conger cinereus
 
Main Ref. Randall, J.E., 1985
Remarks Solitary species common on reef flats and seagrass beds of shallow lagoons but ranges to depths of 80 m on outer reef slopes (Ref. 1602). Also found in estuaries (Ref. 5213). Feeds on fish and crustaceans at night, assuming a pattern of broad dark grey bars (Ref. 3921, 11441). This species exhibits a more dynamic and complex predator-prey relationship with sea kraits, its predator. Many conger or moray eels captured by sea kraits are likely to retaliate and bite their predator (considering krait versus prey body size), increasing the risk of injury on the sea krait's end as prey size increases, thus imposing difficulty on actual feeding by sea kraits (Ref. 118210).
