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.

2024年5月27日 · The leptocephalus is an eel’s transparent, flat larva, and its name means “slim head.” They belong to the superorder Elopomorpha, which is one of the most diverse groups of teleosts. This group contains over 800 species within 4 …

2013年1月12日 · The marine eels and other members of the Superorder Elopomorpha have a leptocephalus larval stage, which are flat and transparent. This group is quite diverse, containing 801 species in 24 orders, 24 families, and 156 genera. They arose in the Cretaceous period 140 million years ago.

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.

2004年1月1日 · The Anguilliformes possesses a unique larval stage termed the leptocephalus that is laterally compressed, leaf-like larva with a transparent body (Smith 1979; Miller and Tsukamoto 2004; Miller...

larva, stage in the development of many animals, occurring after birth or hatching and before the adult form is reached. These immature, active forms are structurally different from the adults and are adapted to a different environment.

2017年4月19日 · Eels, bonefish, ladyfish, and tarpon form a diverse superorder of fishes (Elopomorpha) that all begin their planktonic lives as leptocephalus larvae, which are characterized by long and laterally compressed bodies that are almost completely transparent.

2020年10月22日 · Leptocephali are the unique larvae of eels and their relatives of the teleost superorder Elopomorpha that have remained poorly understood despite their ubiquitous presence at tropical to temperate latitudes. This review examines recent advancements in understanding the behavioral ecology and distribution of leptocephali.

One of these is the Leptocephalus of the American eel, Angwilla Ckr1j8ypa. We have taken pleasure in associating the name of Grassi with this species in recognition of his identification of Leptocephalus breoioeps with tl1e European eel.
