Hagfish, of the class Myxini / m ɪ k ˈ s aɪ n aɪ / (also known as Hyperotreti) and order Myxiniformes / m ɪ k ˈ s ɪ n ɪ f ɔːr m iː z /, are eel-shaped jawless fish (occasionally called slime eels). Hagfish are the only known living animals that have a skull but no vertebral column, although they do have rudimentary vertebrae.

3 mag 2024 · Eel-like in shape, hagfishes are scaleless, soft-skinned creatures with paired thick barbels on the end of the snout. Depending on the species, they grow to about 40 to 100 cm (16 to 40 inches) long. Primitive vertebrates, hagfishes have a tail fin (but no paired fins) and no jaws or bones.

16 gen 2024 · Researchers found that the slime eel, or hagfish, known for deluging predators with mucus, tripled the size of its genome hundreds of millions of years ago.
27 ott 2011 · The hagfish releases a quick-setting slime that clogs up the predator’s gills, causing it to gag, choke and flee. Scientists have known about this repulsive defence for decades, but Vincent ...
10 mar 2017 · Hagfish are the only animals with a cranium but no spinal column. They do have a cartilaginous notochord—a skeletal rod that most vertebrates lose in utero—that gives them amazing flexibility.
Hagfish are long, eel-like fish that live in salt water. These fish are also occasionally referred to as “slime eels.” This is because of their ability to produce copious amounts of slime, which is oozed as mucous from glands along their sides.
