Reef-dwelling parrotfish have teeth on their lower and upper jaw that have evolved into an edge for cutting. [13] This cutting edge allows parrotfish to scrape and feed on coral tissue and skeleton. [13] The cutting edge on the teeth of parrotfish resembles a beak, which is the basis for the organism's common name. [13]
Parrotfish are named for their dentition, [5] which is distinct from other fish, including other labrids.Their numerous teeth are arranged in a tightly packed mosaic on the external surface of their jaw bones, forming a parrot-like beak with which they rasp algae from coral and other rocky substrates [6] (which contributes to the process of bioerosion).
