Conger eels spend their entire life in marine waters. Once they reach maturity, which takes between 5 -15 years, they migrate to deep water in the mid-Atlantic to spawn. Conger conger
spawns only once and dies straight after. The larvae drift north eastwards until they reach shallower waters where larval development is completed (Wheeler, 1969). Conger conger
could be confused with the common eel Anguilla anguilla
. However, the conger eel has pointed pectoral fins, the upper jaw overhangs the lower and the dorsal fin originates from further forward on the body.
