Eels - Classification

Classification

This classification follows FishBase in dividing the eels into 15 families. Additional families included in other classifications (notably ITIS and Systema Naturae 2000) are noted below the family with which they are synomized in the Fish Base system.

The origin of the freshwater species has been problematic. Genomic studies indicate they are a monophyletic group which originated among the deep-sea eels.
