The
Anguillidae are a
family of
ray-finned fish that contains the
freshwater eels. The nineteen species and six subspecies in this family are all in the genus
Anguilla. They are elongated fish with snake-like bodies, their long dorsal, caudal and anal fins forming a continuous fringe. They are
catadromous fish, spending their adult lives in fresh water but migrating to the ocean to
spawn. Eels are an important food fish and some species are now
farm-raised but not bred in captivity. Many populations in the wild are now threatened and
Seafood Watch recommend consumers avoid eating anguillid eels.
