leptocephalus

Although not true eels, these fish do have a similar leptocephalus larval form.

There are 16 different families of leptocephalus organisms that include over 70 different species.

Despite this discovery, the name leptocephalus is still used for larval eel.

They are called leptocephalus (Greek for "thin head").

Benthophilus leptocephalus is a deepwater fish of Gobiidae family.

It was described by Paul Pappenheim in 1914, originally under the genus Leptocephalus.

The leptocephalus is the larval form, a stage strikingly different from the adult form the eels will grow into.

Genus "Leptocephalus"

This fish is known to pass through a leptocephalus larval stage, but only metamorphosed (after reaching the fully grown stage) specimens have been available.

Coloconger giganteus (giant leptocephalus) (validity doubtful)

The leptocephalus shrinks as it develops into a larva; the most shrunken larva, stage two, develops by day 70.

Nocomis leptocephalus (Bluehead chub)

Polyporus leptocephalus, commonly known as blackfoot polypore, is an inedible species of mushroom in the genus Polyporus.

A video recording of a naturally swimming leptocephalus filmed at night off the Island of Hawaii shows an example of their swimming behavior:

It was described by David Starr Jordan and John Otterbein Snyder in 1901, originally under the genus Leptocephalus.

It is known from a single leptocephalus specimen which was collected from between Ecuador and the Galapagos Islands, in the central eastern Pacific Ocean.

The Giant leptocephalus (Coloconger giganteus) is an eel in the family Colocongridae (worm eels/short-tail eels).

A leptocephalus (meaning "slim head") is the flat and transparent larva of the eel, marine eels, and other members of the Superorder Elopomorpha.

The second is that the Synaphobranchidae (a specific family of leptocephalus) have telescopic eyes, meaning that there is a tubular eye with a sphere-shaped lens on the top.

Pseudaspius leptocephalus, the Redfin, is a species of cyprinid fish found in eastern Asia where it occurs in the countries of Russia, Mongolia and China.

The bluehead chub, Nocomis leptocephalus, (originally Cirrhitichthys leptocephalus ) is a cyprinid native to North America.

Leptocephalus is a genus that was used for species of larval eels, called leptocephali, that were thought to be new fish species, or whose adult eel species were not known.

Leptocephali (singular leptocephalus) all have laterally compressed bodies that contain transparent jelly-like substances on the inside of the body and a thin layer of muscle with visible myomeres on the outside.

With the discovery of Neocyema erythrosoma in the Northern Atlantic the distance barrier was also overcome and they considered that there was little doubt that Leptocephalus holti was indeed the larval form of Neocyema erythrosoma.

Pink-speckled shrimpgoby (also called Pinkspotted Shrimp Goby), Cryptocentrus leptocephalus, is a goby from the Western Pacific: Indonesia to New Caledonia, north to the Yaeyama Islands, south to northwestern Australia, also Tonga.
