FRESH WATER EEL :
Anguillidae is family of fishes that contains many of the freshwater eels. There are 16 to 20 species in this family, all in genus anguilla. They are catadromous, meaning they spend their lives in freshwater rivers and return to the ocean to spawn. The young eel larvae, called leptocephali, consume plankton close to shore. They grow larger in size, and in their next growth stage are called glass eels . At this stage they live in tidal estuaries until they reach one year of age, at which they are known as elvers . Elvers travel upstream in freshwater rivers where they grow to adulthood. Some details of eel reproduction are as yet unknown.Freshwater eels are elongate with tubelike, snake-shaped bodies.
