What goes in must come out in some form, and with parrotfish, what comes out is sand.As the name might suggest, these tropical fish, with their big beaks and bright colors, look like their land-based counterparts.

Hard coral is no match for the large beak of the parrotfish, which researchers have recently found is formed by some of the strongest teeth in the world.https://ocean.si.edu/ocean-life/fish/tough-teeth-and-parrotfish-poop -- source link
