Watch the hagfish slime in action

The special slime secreted by hagfish could be turned into clothes, scientist say.

The hagfish is a spineless creature that lives at the bottom of the ocean and dates back as far as 500 million years.

It doesn't have jaws either, but has a special way of defending itself - letting out slime!

So when a shark bites a hagfish, its mouth and gills are quickly covered in slime and the shark has to back off, or face suffocation.
