The hagfishes have a vertebrate pattern of organization but have some physiological and morphological characteristics that are distinctly ‘invertebrate’ in nature. For example and important for this review, unlike most other marine fish, hagfish are exclusively marine osmoconformers. The blood plasma...

Hagfishes (Myxinidae), a family of jawless marine pre-vertebrates, hold a unique evolutionary position, sharing a joint ancestor with the entire vertebrate lineage. They are thought to fulfil primarily the ecological niche of scavengers in the deep ocean

Evolution of Vertebrate Brains A.B.Butler, inEncyclopedia of Neuroscience, 2009 Hagfishes Thebrainof hagfishes is largely terra incognita, due to the difficulty of obtaining and working with these animals (which are covered with a copious quantity of secreted mucus) in a laboratory setting. Also...
Recently, using the Pacific hagfish (Eptatretus stouti, class Agnatha), a jawless scaleless marine vertebrate of ancient lineage, we determined that the deduced amino acid sequence of one thread IF chain (alpha, 66.6 kDa, native pI 7.5) contained an atypical, threonine-rich central rod domain...
The original word coined for these vertebrate cartilage-like tissues, “vorknorpel” (German: pre-cartilage) is thus also used to refer to connective tissues in invertebrate mollusks and vertebrate structures like the sesamoid nodule in the Achilles tendon [49,50]. Even still, these early ...
