What fish can tuck itself in at night \/\/!|| [)@\/!$
The Parrot Fish can tuck itself in at night. Certain species of the fish will secrete mucous from an organ on their heads and "cocoon" themselves in it at night. It is speculated that the mucous disguises their scent and protects them from night predators.
Another interesting fact about the Parrot Fish is that it can change color and gender. A dominant male will have a group of females, and when the male dies one of the females will change color and gender to become the dominant male.
There are about 80 species of Parrot Fish living in tropical reefs. They live an average of 7 years and can grow up to 4 feet long.
