[1] [2] [3] These small eels live in burrows on the sea floor and get their name from the behavior of poking their heads from their burrows while most of their bodies remain hidden. Since they tend to live in groups, the many eel heads "growing" from the sea floor resemble the plants in a garden. They vary in color and size depending on the ...
The true Kuhli loach (Pangio kuhlii), which can be used synonymously with "coolie" loach, [2] [3] occasionally referred to as eel loach, is a small eel-like freshwater fish belonging to the loach family .

The group includes pelagic, benthic, and even parasitic species, although all have a similar body form. Some species are viviparous , giving birth to live young, rather than laying eggs. They range in size from Grammanoides opisthodon which measures just 5 centimetres (2.0 in) in length, to Lamprogrammus shcherbachevi at 2 metres (6.6 ft) in ...
The cusk-eel family, Ophidiidae, is a group of marine bony fishes in the Ophidiiformes order. The scientific name is from the Greek ophis meaning "snake", and refers to their eel-like appearance. True eels diverged from other ray-finned fish during the Jurassic, while cusk-eels are part of the Percomorpha clade, along with tuna, perch ...
Synbranchiformes, often called swamp eels, though that name can also refer specifically to Synbranchidae, is an order of ray-finned fishes that are eel-like but have spiny rays, indicating that they belong to the superorder Acanthopterygii.
The Asian swamp eel is a freshwater, eel-like fish belonging to the family Synbranchidae (swamp eels). [4] Some work indicates that the species should be split into three geographical clades or cryptic species, although these were not given nomenclatural names, as the taxonomic synonymy was too complex to sort out at the time.
The term "eel" is also used for some other eel-shaped fish, such as electric eels (genus Electrophorus), swamp eels (order Synbranchiformes), and deep-sea spiny eels (family Notacanthidae). However, these other clades , with the exception of deep-sea spiny eels, whose order Notacanthiformes is the sister clade to true eels, evolved their eel ...
