Inhabits reef areas. The parrotfish's teeth are fused together, enabling them to scrape away hard coral outer skeletons to get at polyps inside. These fish are thought to be a major factor in reef recycling. Occasionally a female will change sex, increase in size, and take on a distinct appearance as a terminal-phase male. This is usually done to replace a missing male. Edibility is poor. Range is Bermuda and Florida to Brazil.
