Genera
As of February 2011, about 77 species are known, in 5 genera (two are being retained in the no-longer recognized genus Paramyxine and are awaiting taxonomic issues to be resolved before being transferred to Eptatretus (see below)). A number of the species have only been recently discovered, living at depths of several hundred metres.
- Eptatretus
- Myxine
- Nemamyxine
- Neomyxine
- Notomyxine
- Paramyxine (Note that this genus is considered synonymous with Eptatretus and most species have been moved into that genus with the exception of the following two which are homonyms of current Eptatretus species. Since the current Eptatretus species are junior (i.e., described later) to the two following species, they must be renamed and then the two remaining "paramyxines" will be transferred to Eptatretus.)

Famous quotes containing the word genera:
“Genius detects through the fly, through the caterpillar, through the grub, through the egg, the constant individual; through countless individuals the fixed species; through many species the genus; through all genera the steadfast type; through all the kingdoms of organized life the eternal unity. Nature is a mutable cloud which is always and never the same.”
—Ralph Waldo Emerson (1803–1882)
