Parrotfish

Family

The parrotfish belongs to the Scaridae family.  They do resemble wrasses but for their fused dentition, resulting in beak-like plates the parrots on land are renowned for. It enables them to scrape and rasp and break and crush filamentous algae, herbivorous as they are, from dead coral rock. Some parrotfish also gorge on particles from the surface of coarse sand and feast upon living corals, seagrass and leafy algae. Sounds are characteristic for the habitats of the parrotfish, creating their own ‘audible’  world. It’s intriguing to hear the sound of subdued roaring, whistling, grinding and creaking noises , coming from their mill-like plates.

The parrotfish doesn’t shy way from mingling with surgeonfishes, travelling considerable distances between their feeding grounds and sleeping and resting zones. It is  diurnal, the body stout, compressed, oval and well-proportioned. At night it retreats in crevices of reefs, wrapped in a layer of mucus it produces to deter predators.
