Hagfish Slime

When threatened, hagfish secrete copious amounts of slime from some 100 glands along its body. The microfibrous substance expands to up to 20 L (5¼ gallons) when dissolved in water. 
The slime is thought to be a defense mechanism against predators. In addition to distracting the predator, the slime has the potential to clog and impair the function of the predator’s gills. This allows the hagfish to escape as it twists itself into a knot to free itself of its slimy secretions.
