Eels in this so-called "recruitment" developmental stage are known as glass eels because of the transparency of their bodies. The term typically refers to a transparent eel of the family Anguillidae. It is applied to an intermediary stage in the eel's complex life history between the leptocephalus stage and the juvenile (elver) stage.
European eels live through 5 stages of development: larva (leptocephalus), glass eel, elver, yellow eel, and silver eel.Adults in the yellow phase are normally around 45–65 centimetres (18–26 in) and rarely reach more than 1.0 metre (3 ft 3 in), but can reach a length of up to 1.33 metres (4 ft 4 in) in exceptional cases.

The term "eel" is also used for some other eel-shaped fish, such as electric eels (genus Electrophorus), swamp eels (order Synbranchiformes), and deep-sea spiny eels (family Notacanthidae). However, these other clades , with the exception of deep-sea spiny eels, whose order Notacanthiformes is the sister clade to true eels, evolved their eel ...
The New Zealand longfin eel (Anguilla dieffenbachii) is a species of freshwater eel that is endemic to New Zealand. It is the largest freshwater eel in New Zealand and the only endemic species – the other eels found in New Zealand are the native shortfin eel (Anguilla australis), also found in Australia, and the naturally introduced Australian longfin eel (Anguilla reinhardtii).
Moray eel. Moray eels, or Muraenidae (/ ˈ m ɒr eɪ, m ə ˈ r eɪ /), are a family of eels whose members are found worldwide. There are approximately 200 species in 15 genera which are almost exclusively marine, but several species are regularly seen in brackish water, and a few are found in fresh water.
Life cycle of eels. The adults of this species are demersal, living on the bottom of fresh to brackish waters, in rivers, lakes, and tributaries. [2] This species and all anguillid eels are catadromous, migrating sometimes long distances out into the open ocean to spawning over deep water. [2]
This variability allows some eels to live even 50–70 years, however the lifespan of freshwater eels is not well documented. Very little is known about the mechanics of fertilization and spawning, and the time it takes these eels to hatch from their eggs is variable. [ 25 ]
