The hagfishes are renowned for their ability to produce vast quantities of slime when provoked. Hagfishes do lots of amazing things, like making buckets of slime and feeding through their skin, but one of their most impressive tricks has to be their ability to tie themselves in knots.Knot tying is used by hagfishes to wipe slime off themselves if they get tangled up in it, and it is also used during feeding as a way to brace themselves against a carcass so they can tear off pieces to eat.
