The queen triggerfish reaches 24 in, though most only are about half that length. It is typically blue, purple, turquoise and green with a yellowish throat, and light blue lines on the fins and head. It can change colour somewhat to match its surroundings, or if subjected to stress. In the western Atlantic, it ranges from Canada to southern Brazil, and is reasonably common in Florida, the Bahamas and the Caribbean. The queen triggerfish is typically found at coral and rocky reefs in depths of 10–100 feet, but it can occur as deep as 900 feet and sometimes over areas with sand or sea grass. The sketch is direct to watercolor without ink. Holbein and Daniel Smith watercolors in a Stillman and Birn sketchbook.
