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]

A leptocephalus (meaning "slim head" [1]) is the flat and transparent larva of 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.

May 27, 2024 · 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 …

Apr 25, 2023 · Leptocephali have flat bodies filled with jelly-like substances, surrounded by a thin layer of muscle. Their gut is a simple tube, and they lack pelvic fins. The lifecycle of an eel begins with eggs. These eggs are large compared to many other species of fish. When the eggs hatch, the stage of the emerging species is called preleptocephalus.

Eels are a type of fish that resembles a snake. They’re known for their smooth slippery bodies that range in length from 5 cms to 4 meters depending on the type of eel. Their weight ranges from 30 grams to 25 kgs while there can be gray eels or black eels to colorful ones.

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.

Juvenile bichirs look more eel-like with a uniformly thin body and a flat head, but adult bichirs grow into massive dragons that reach up to two feet in length. If you’re looking for an eel to add a touch of wildness to your monster tank, there’s nothing better than this ancient fish to add to the list.
