1. The Pacific Ocean Hagfish has a disgusting way of defending itself.

2. Agnatha are jawless fish. Lampreys and hagfish are in this class

3. They're kind of like eels or hagfish or lampreys, but different.

4. The hagfish also represents an important evolutionary step in the development of vision.

5. Koi, along with catfish, goatfish, hagfish, sturgeon, zebrafish, some species of shark and other carp, have Barbels

6. Craniates (Craniata) are a group of chordates that includes hagfish, lampreys, and jawed vertebrates such as amphibians, birds, reptiles, mammals, and fishes

7. The brain of the Agnatha, especially of the hagfish, is discussed from the viewpoint of the telencephalon and the olfactory, visual, trigeminal, and vestibulolateral sensory systems

8. In the most primitive vertebrates, the hagfish and lampreys, the kidney is unusually simple: it consists of a row of nephrons, each emptying directly into the archinephric duct.

9. If We Can Get Past the Ickiness, Hagfish Slime May Actually Be Useful to Us The gelatinous glop could be the key to everything from bio-inspired kevlar to shark defense for divers

10. The microscopy studies of the Aortae of the lobster, horseshoe crab and whelk revealed tissue structures which differ widely from each other as well as from the structures of the lamprey and hagfish.

11. ‘Thus, there exist two competing theories about the interrelationships of Craniates, i.e., animals with a skull.’ ‘Unfortunately, there are few quantitative data on the relative sizes of major brain divisions in most Craniates.’ ‘Hagfish are the oldest lineage of Craniates and thus are …

12. Given our current understanding of craniate phylogeny, the observation of programmed genome reorganization in both lamprey and hagfish could be considered evidence that chromatin diminution was characteristic of the common ancestor of all Craniates, or of a basal taxon with a genome biology that was otherwise very similar to the craniate ancestor.
