hagfish

(ˈhæɡˌfɪʃ)

hag·fish

(hăg′fĭsh′)
Any of various jawless fish that resemble eels and may be related to the lampreys. Hagfish have several hearts, glands that produce slime, and tentacles around the mouth. They do not have eyes, a backbone, or a stomach. Hagfish often feed on dead or dying fish by boring into them and eating them from the inside.

Although further studies will need to examine whether an aqp0-like ortholog exists in hagfishes (Hyperotreti), the expression of the aqp01 gene in the eye of the sea lamprey (Petromyzoti marinus) is consistent with the evolution of multifocal lenses in Hyperoartia after the lineage diverged from Hyperotreti (Gustafsson et al.
The two main taxonomic groups of agnathan or cyclostome fish are Hyperoartia, lampreys and Hyperotreti, and hagfish (for a review of agnathan ion and water homeostasis see Karnaky, 1998; Evans and Claiborne, 2009).
In hagfish, while there is no genomic information available for the Hyperotreti, two aquaporin genes have been isolated and studied.
