Parrotfish Have Been Caught ‘Farming’ Coral Reefs – Atlas Obscura

Octopus gardens get all the attention from songwriters, but maybe it’s time someone wrote a ditty about parrotfish algae farms. According to new research, the fascinating fish—also responsible for pooping out Hawaii’s white-sand beaches—actually “farms” its food in coral reefs.

A pair of research papers have stated that some species of parrotfish, colorful creatures with fused teeth that form a bird-like beak, revisit the same feeding spots at regular intervals, according to a story on Futurity. Like farmers on land, they seem to spread out their feedings in such a way that new crops of algae can grow in their favored spots, and even go so far as to defend the spots from other sea creatures that might try to steal a crop before its harvest time.
