Blue parrotfish

The blue parrotfish (Scarus coeruleus) is a member of the parrotfish genus Scarus. It is found on coral reefs in shallow water in the tropical and subtropical parts of the western Atlantic Ocean and the Caribbean Sea. They usually forage in a group of 500 individuals for spawning and deterring predators while feeding.

Distribution

Blue parrotfish are found on coral reefs at depths of 3–25 m (9.8–82.0 ft) in the western Atlantic from Maryland in the United States to Bermuda, the Bahamas, and south to Brazil. They are also found throughout the West Indies but are absent from the northern part of the Gulf of Mexico. Juveniles are found in beds of turtle grass (Thalassia testudinum).

The Scarus Coeruleus fish greatly depend on coral reef systems to provide them with various food sources; however, this ecosystem has become threatened, which has now put the blue parrotfish and many other species endangered of becoming extinct from lack of food availability.

Behaviour

Their diet consists of small organisms found in the algae that they scrape off rocks. They are described as professional sand-suckers, due to their foraging of food amongst the sandy areas that surround the reef. They spend 80 percent of their time searching for food.
