Leptocephalus larva. 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 ...
Although Schmidt did not directly observe eel spawning, or even find ready-to-spawn adult eels, he deduced the following about the life history of the eel, based on the size distribution of the leptocephali he collected: The larvae of European eels travel with the Gulf Stream across the Atlantic Ocean from the Sargasso Sea, and grow to 75–90 ...
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.

Leptocephalus is a genus that was used for species of larval eels, called leptocephali.Leptocephali larvae differ so much in appearance from their adults. When first discovered, leptocephali were thought to be a distinct type of fish, [1] not an eel specie.
Eels begin life as flat and transparent larvae, called leptocephali. Eel larvae drift in the sea's surface waters, feeding on marine snow , small particles that float in the water. Eel larvae then metamorphose into glass eels and become elvers before finally seeking out their juvenile and adult habitats. [ 8 ]
