Eels are aquatic animals that have a cylindrical and elongated shape very similar to that of snakes; the length of the body of males ranges from 50 to 70 centimeters, while females can reach 2 meters. Usually, their skin is of a grayish color, characteristic of fish or greenish-brown with a viscous texture due to the mucosa by which they are covered to facilitate their movement. They have small scales and 2 fins that arise from the back or upper part of their head and extend throughout their entire body.
Eels are a migratory species, they live in freshwaters of rivers, salty waters of the sea, in brackish waters of dissolved salts, and for short periods of time they can also be found on land. Their location is totally dependent on the stage of the reproductive cycle in which they are. When they reach reproductive maturity, which is 8 to 10 years old, the females migrate from the river to the sea to spawn, when the small leptocephalus is born, aided by the current, they migrate again to the fresh waters where they transform into eels by metamorphosis. The salinity level of the water where they are plays a very important role in determining the sex of the eel.
Its reproduction process is very complex, since when it begins its maturation, it migrates from the fresh waters to the sea where it mates, lays thousands of eggs in a nest made from the male’s saliva, and after that, it dies. Eels live for 8 to 12 years, being the longest-lived females.
