The mouth of hagfishes is armed with a protractable and retractable cartilaginous plate which bears two pairs of comb-shaped horny teeth (the "rasping tongue").
The skeleton of hagfishes is made up by a complex assemblage of cartilaginous bars (see figure on the Craniata page), which serve as antagonists to an equally complex head musculature.
A modern hagfish, the Pacific hagfish Eptatretus (top), shows some of the diagnostic features of the group: the tentacles surrounding the snout, the left oesophagocutaneous opening (in the rear of the gill openings), and the series of large, ventrolateral slime glands.

 Evolutionary analysis of hagfish amelogenin
Hagfishes are eel-shaped, jawless craniates belonging to the Hyperotreti, thesister-group of vertebrates (Janvier, 1996).
The presenceof amelogenin in hagfishes implies either that this gene has another function(at least in hagfishes), or, if we assume that the ancestors of hagfishes oncehad a mineralized skeleton (as suggested by most early phylogenies), that thisapparently inactive gene has been retained for over 300 My (the age of theoldest known hagfish).

Hagfishes are one of two clades of recent jawless fishes that are an offshoot of the early radiation of jawless vertebrates.
Quartet mapping reveals that within each paralog group the hagfish sequences are statistically more closely related to gnathostome Hox genes than with either amphioxus or lamprey genes.
These results support two assumptions about the history of Hox genes: (1) The association of hagfish homeobox sequences with gnathostome sequences suggests that at least one Hox cluster duplication event happened in the stem of vertebrates, i.e., prior to the most recent common ancestor of jawed and jawless vertebrates.
