Family and
Suborder page
A number of classifications of eels exist; some, such as FishBase, divide eels into 20 families, whereas other classifications such as ITIS and Systema Naturae 2000 include additional eel families, which are noted below the family with which they are synonymized in the FishBase system.
Identifying the origin of the freshwater species is considered to be problematic; however, genomic studies indicate they are a monophyletic group which originated among the deep-sea eels.
