(Phys.org) —Perhaps the worst fate to be had in the sea is to be slimed by the hagfish. The proteinaceous goo they secrete has gotten many a hagfish out of bind by gumming up the gills and suffocating a would be attacker. ...
(PhysOrg.com) -- A new study in Canada has shown that the primitive fish called the Hagfish, which has the habit of burrowing into dead or dying creatures on the sea bed, eats by absorption through its skin and gills as well ...

Hagfish are marine craniates of the class Agnatha or Myxini, also known as Hyperotreti. Some researchers regard Myxini as not belonging to the subphylum Vertebrata. That is, they are the only living animals that have a skull but not a vertebral column.
Despite their name, there is some debate about whether they are strictly fish (as there is for lampreys), since they belong to a much more primitive lineage than any other group that is placed in the category of fish (Chondrichthyes and Osteichthyes). The earliest fossil record dates back approximately 550 million years, or earlier to the Lower Cambrian period. Their unusual feeding habits and slime-producing capabilities have led members of the scientific community and popular media to dub the hagfish as the most "disgusting" of all sea creatures. Although hagfish are sometimes called "slime eels", they are not eels at all.
