Slime
The Atlantic hagfish, scientifically known as Myxine glutinosa, is an unusual sea creature. Its body is covered with special glands that can emit a sticky slime. In fact, a single hagfish can produce enough slime at one time to fill a milk jug. This has earned it the name "slime eel", although it is really not an eel at all. A hagfish will actually "sneeze" when its own nostrils fill with slime. Hagfish slime is different that any other natural slime secretion in that it is reinforced with tiny fibers. These fibers make the slime strong and difficult to remove. It is believed that the hagfish uses this slime to protect itself from predators. It can also be used to easily produce a protective cocoon for the hagfish. It is believed that this slime can actually suffocate predators by clogging their gills if they come in contact with it. The hagfish has a trick for escaping this slime cocoon. Believe it or not, this animal can tie itself in a knot and then pass the knot down the length of its body to wipe the slime away. Hope this helps! :) xxx
No, but they could suffocate fish with their slime.

The answer is, of course, the Hagfish. There are plenty of other correct answers, but the Hagfish is the legendary one, producing several times the volume of its own body in slime in seconds.
It can be found in many forms. Snails and slugs produce the most common slimes but more uncommon animals are frogs, toads, caecilians, salamanders, newts, and hagfish.
A Hagfish is an ancient, eel-like creature that lives at great depths in the oceans. They produce such large quantities of slime on their bodies as a defence, that I don't think they are preyed up on by any one. Though they have a skull, there is no spine - which enables then to literally tie themselves into a knot!

Recently scientists have become interested in the unique slime that hagfish produce and that research will probably lead to some new technology, so yes the jawless fish are useful to man.
The first vertebrates (as far as is known) were a group of extinct*, jawless, heavily-armored fishes called Ostracaderms. *There are a few zoologists who feel that the hagfish and possibly the lamprey and slime hag are ostracaderms, but I disagree. I'm not at all sure that the hagfish and slime hag are true vertebrates.
Cephalopods (cuttlefish, squid, octopus and nautilus) have three hearts, two that pump blood to the gills and one that pumps blood round the rest of the body. Their blood is blue.Earthworms have multiple hearts, one in each segment of their body.And the hagfish (a slimy sea creature looking like a cross between an eel and a slug) has four hearts, two brains, a skull but no backbone. An adult hagfish can produce enough slime to turn a 20 liter (5 gallon) bucket of water into slime in a few minutes.
