The Midnight parrotfish

The Midnight parrotfish, Scarus coelestinus, is a large fish with blue and black markings. Their heads are unscaled and there is a blue band in between the eyes. This blue color helps them blend end with the deep blue color of the water around the reefs as well. Their size can reach up to 80 centimeters and can weigh up to 15 pounds. The only place the parrotfish was spotted was at Looe Key on Thursday, as well as other species of parrotfish. They have a beak-like mouth that is used to scrape algae off the seafloor and substrates such as corals. They are only found in coral reefs around 10-70 meters deep in the Caribbean as well as the Atlantic Ocean around Bermuda, Florida, as well as Brazil (http://marinebio.org/species.asp?id=605). These parrotfish feed on mainly algae off corals. Their beaks can even be heard scraping off rocks and biting off pieces of coral. These pieces of coral can be broken down through their digestive system and excreted as sand. These fish are no threat to humans, but they are often sold commercially for aquariums and different displays because of their beauty. They are not an abundant species and may be declining in numbers according to current evidence. An interesting fact about the fish is that when they are ready to sleep, they produce mucus bubbles from their mouth, which makes a clear “nightgown” to protect them from predators. Some scientists say it masks their scent, making them harder to find (https://www.keywestaquarium.com/parrotfish).
