@jonny when a hagfish is caught by a predator, it releases a strange fibrous slime that expands to 10000 times its original size within half a second. This slime clogs up the predator's gills, forcing them to let go of the hagfish to avoid suffocating.
The hagfish will then twist itself into a knot which travels from head to tail, removing the slime off its own body.
in 2017, a road accident in Oregon resulted in 3.4 metric tons of hagfish being spilled all over the highway and ended up blocking it with their slime.
