Conger eel The European conger (Conger conger) is a species of conger of the own circle of relatives Congridae. It is the heaviest eel withinside the global and local to the northeast Atlantic, such as the Mediterranean Sea.
Description and behavior Conger eel
European congers have a mean grownup period of 1.five m (five feet), a most acknowledged period of round 2.133 m (7 feet) (in all likelihood up to a few metres (nine feet 10 in) for the largests specimens),[2] and most weight of approximately seventy two kg (159 lb),[3] making them the most important eels withinside the global with the aid of using weight.
They may be rivaled or marginally passed in period with the aid of using the most important species of moray eel however those have a tendency to be slenderer and as a consequence weigh much less than the bigger congers.
Average specimens stuck will weigh handiest 2.five to twenty-five kg (five.five to 55.1 lb).[5][6] Females, with a mean period at sexual adulthood of two m (6 feet 7 in), are a lot large than men, with a mean period at sexual adulthood of 1.2 m (three feet eleven in).[7]
The frame could be very long, anguilliform, with out scales. The coloration is generally grey, however also can be blackish. The stomach is white. A row of small white spots is aligned alongside the lateral line.
The head is sort of conical, and barely depressed. The snout is rounded and prominent, with lateral olfactory holes. The massive gill openings are withinside the lateral position. The conical enamel are organized in rows at the jaws. The dorsal and anal fins are confluent with caudal fin. Pectoral fins are gift, at the same time as ventral fins are absent.

Conger eels have conduct just like moray eels. They generally stay among rocks in holes, or “eel pits”, occasionally in a single hollow collectively with moray eels.
They pop out from their holes at night time to hunt. These nocturnal predators particularly feed on fish, cephalopods, and crustaceans, despite the fact that they’re idea to scavenge on lifeless and rotting fish, in addition to actively hunt stay fish.[8] Congers may be competitive to humans, and massive specimens can pose a threat to divers.

Distribution Conger eel
This species may be observed withinside the japanese Atlantic from Norway and Iceland to Senegal, and additionally withinside the Mediterranean and Black Sea[10] at 0–500 m of depth, despite the fact that they will attain depths of 3600 m for the duration of their migrations.
It is occasionally visible in very shallow water with the aid of using the shore, however also can cross right all the way down to 1,one hundred seventy m (three,840 feet). It is generally gift on rough, rocky, damaged ground, near the coast while young, transferring to deeper waters while grownup.
Migration and reproduction
When diving, their our bodies go through a transformation, with the reproductive organs of each women and men growing in length and the skeleton lowering in mass and the enamel falling out.[12] Female conger eels seem to boom in weight and length extra than the men.
[citation needed] Conger eels then make migrations to spawning regions withinside the Mediterranean and the Atlantic, “despite the fact that the life of 1 or a couple of spawning grounds for the species stays uncertain”.
[13] The woman conger eels produce numerous million eggs, and each the ladies and men die after spawning. Once hatched, the larval conger eels start to swim lower back to shallower waters, in which they stay till they attain eel2 adulthood. They then migrate to copy the cycle.Conger eel
