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.
The mature eels then die, their eggs floating to the surface to hatch into very flat leaf-like larvae (called leptocephalus) that then drift along large oceanic currents back to New Zealand. [14] [17] This drifting is thought to take up to 15 months. [16] There have been no recorded captures of either the eggs or larvae of longfin eels. [14]
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.
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 larvae recruit from the sea as small adults when they lack colour and are transparent-giving them the name "glass eel". Tropical species have year-round recruitment, whereas temperate species such as the short-finned eel have strong seasonal recruitment. [ 7 ]
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 ...
The pink amperima sea cucumber, nicknamed the “Barbie pig,” is one of the largest invertebrates living on the deep-sea floor. Along with the transparent unicumber, the creature is a type of ...
Congriscus megastomus is an eel in the family Congridae (conger/garden eels). [4] It was described by Albert Günther in 1877, originally under the genus Congromuraena. [5] It is a marine, temperate-water dwelling eel which is known from Japan and the Kyushu–Palau Ridge, in the northwestern Pacific Ocean.
