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.
A leptocephalus (meaning "slim head" [1]) is the flat and transparent larva of the eel, marine eels, and other members of the superorder Elopomorpha. This is one of the most diverse groups of teleosts, containing 801 species in 4 orders, 24 families, and 156 genera. This group is thought to have arisen in the Cretaceous period over 140 million ...

Based on studies of several species of snipe eel in the Sargasso Sea and off the coast of California, it seems that snipe eels spawn mainly in the spring, but also into early summer. The juvenile forms of eels are generally called leptocephali (meaning "small head") and do not look like their adult forms. They are flat and transparent, taking ...
Not much is known about the reproductive habits of the pelican eel. Similar to other eels, when pelican eels are first born, they start in the leptocephalus stage, meaning that they are extremely thin and transparent. [20] Until they reach their juvenile stage, they interestingly have very small body organs and do not contain any red blood cells.
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 short-finned eel (Anguilla australis), also known as the shortfin eel, is one of the 15 species of eel in the family Anguillidae.It is native to the lakes, dams and coastal rivers of south-eastern Australia, New Zealand, and much of the South Pacific, including New Caledonia, Norfolk Island, Lord Howe Island, Tahiti, and Fiji.
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 ...
