Have you been trying to think of a way to sleep at night and remain safe from vampires? Bet you’ve never considered a snot bubble! For some parrotfish, a sleeping bag of mucus is the perfect protection from blood-sucking parasites. Some researchers even think parrotfish mucus serves as an early warning system to predators. So where does all of the mucus come from? Parrotfish have it in the glands located in their gills. Each night, it takes them about an hour to get ready for bed by constructing their mucus cocoon.
Next time you encounter a blood-sucker, instead of the garlic consider some mucus for protection.
