What is scarus coeruleus?

Scarus coeruleus is a species of parrotfish found in the western Atlantic Ocean, particularly in the Caribbean Sea. It is commonly known as the blue parrotfish due to its striking blue color. The fish can grow up to 60 cm in length and 3.5 kg in weight. It is primarily herbivorous and feeds on algae and seagrasses. Scarus coeruleus is an important species for coral reef ecosystems as it contributes to the process of bioerosion, which helps maintain the health of the reef. It is also harvested for consumption by humans, though overfishing has caused a decline in its population in some areas. The fish is considered a vulnerable species by the International Union for Conservation of Nature (IUCN).
