Anguilliformes

Also known as eel, eels

Eels are ray-finned fish belonging to the order Anguilliformes (), which consists of eight suborders, 20 families, 164 genera, and about 1000 species. Eels undergo considerable development from the early larval stage to the eventual adult stage and are usually predators.

OverviewAI-generated

Anguilliformes is an order of animals within the class Teleostei and phylum Chordata. It falls under the parent taxa Elopomorpha, Actinopterygii, and Actinopteri. The group is commonly known as eels and morays, with other names including Angerjalised, Anguilliformi, and ウナギ目. Its taxonomic status is accepted.

Members of this order inhabit marine, brackish, and freshwater environments. The taxon is a source of eel as food. Records from various institutions, including CM and UWFC, document occurrences in Italy, Brazil, Antarctica, and the United States. The order has been described in sources such as the Armenian Soviet Encyclopedia, Encyclopædia Britannica 11th edition, and New International Encyclopedia.

鰻魚是鰻鱺目（学名：Anguilliformes）分類下的物種總稱，包含20科111屬總共大約800種。部分鰻魚和鮭魚一樣具有洄游特性。另外有些魚類如八目鰻、電鰻、黃鱔等，長相類似鰻魚而容易被誤認，但在分類上屬於完全獨立於鰻魚外的演化支。

The term "eel" is also used for some other eel-shaped fish, such as electric eels (genus Electrophorus), swamp eels (order Synbranchiformes), slime eels (class Myxini), 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-like shapes independently from the true eels. As a main rule, most eels are marine. Exceptions are the catadromous genus Anguilla and the freshwater moray, which spend most of their life in freshwater, the anadromous rice-paddy eel, which spawns in freshwater, and the freshwater snake eel Stictorhinus.
