Stoplight Parrotfish

The Stoplight Parrotfish, Sparisoma viride, is found in coral reefs in various locations, including Florida, the Caribbean Sea, the Gulf of Mexico, Bermuda, and as far south as Brazil. A notable trait of this species, common among parrotfish, is its ability to change sexes. Typically, it grows to a length of 1 to 1.5 feet, but can sometimes reach up to 2 feet.

This species is known for its dramatic color changes between its initial phase, where it can be either male or female, and its terminal phase, where it is distinctly male. In its initial phase, the Stoplight Parrotfish’s scales on its underside can quickly shift from red to white, showcasing a remarkable color variation.
