The European conger (Conger conger) is a species of conger of the family Congridae. It is the heaviest eel in the world and native to the northeast Atlantic, including the Mediterranean Sea.
Description and behavior
European congers have an average adult length of 1.5 m (5 ft), a maximum known length of around 2.133 m (7 ft) (possibly up to 3 metres (9 ft 10 in) for the largest specimens),[2] and maximum weight of roughly 72 kg (159 lb),[3] making them the largest eels in the world by weight. They can be rivaled or marginally exceeded in length by the largest species of moray eel but these tend to be slenderer and thus weigh less than the larger congers.[4] Average specimens caught will weigh only 2.5 to 25 kg (5.5 to 55.1 lb).[5][6] Females, with an average length at sexual maturity of 2 m (6 ft 7 in), are much larger than males, with an average length at sexual maturity of 1.2 m (3 ft 11 in).[7]

Migration and reproduction
When conger eels are between 5 and 15 years old, their bodies undergo a transformation, with the reproductive organs of both males and females increasing in size and the skeleton reducing in mass and the teeth falling out.[12] Females appear to increase in weight and size more than the males.[citation needed] Conger eels then make migrations to spawning areas in the Mediterranean and the Atlantic, "although the existence of one or multiple spawning grounds for the species remains uncertain".[13] The female conger eels produce several million eggs, and both the females and males die after spawning. Once hatched, the larval conger eels begin to swim back to shallower waters, where they live until they reach maturity. They then migrate to repeat the cycle.[14]
