So to solve the problem, you spit. That is, you swim into a cozy little part of the coral and you start spitting up mucus to wrap yourself inside of. That’s what parrotfish and wrasses do each evening!

These fish have mucus glands near their mouths that allows them to create their own mosquito nets each night. No moray eel wants to eat a fish wrapped in what looks like a spider web. And most parasites can’t get through the mucus!
And humans can also protect themselves from predators and parasites with mucus. If you’re bothered by a bully or someone who constantly borrows money from you, try coating yourself with mucus. I’ll bet they stay away!
