Wake up on the wrong side of the bed? Well, imagine what a parrotfish feels like after spending the night covered with mucus.
The parrotfish is a colorful reef fish that eats coral. Its name comes from the fact that its mouth, which contains large fused-together teeth, resembles the beak of a tropical bird.
The parrotfish just as easily could have been called the mucusfish. When it retires for the evening, nestling on a reef bottom, the parrotfish starts to secrete a transparent ooze that forms a kind of gooey cocoon. It takes about thirty minutes for the cocoon to fully form, and while it lacks the sex appeal of, say, silk pajamas, the covering helps protect the parrotfish from night predators like moray eels.
