The queen parrotfish (Scarus vetula) is a colorful fish that lives in the ocean. It's a type of ray-finned fish called a parrotfish, known for its strong, beak-like mouth. You can find these fish on coral reefs in warm parts of the Atlantic Ocean and the Caribbean Sea. People sometimes call them by other names like blownose or blue parrotfish. Young males and all female queen parrotfish are a reddish-brown color. But adult males look very different, with a bluish-green body. This fish is common in its ocean homes. Experts say it is a "least concern" species, meaning it's not currently in danger.

What the Queen Parrotfish Looks Like
Adult queen parrotfish are strong, oval-shaped fish. They have a mouth that looks like a bird's beak. They can grow to be about 60 centimeters (24 inches) long.
These fish have two main color phases. Smaller fish, which are almost all female, are reddish-brown or grayish-brown. They have a lighter head and a white stripe along their side. Females keep this color even as they grow bigger.
When females reach about 25 centimeters (10 inches) long, they can change into males. These larger males then change their color. They become a pale bluish-green. They also get blue spots near their mouth, yellowish lines between their mouth and eye, and light blue bars on their fins.
Where the Queen Parrotfish Lives
The queen parrotfish lives in the warm waters of the western Atlantic Ocean. You can find them in the Caribbean Sea and the southern Gulf of Mexico. They like to live on both rocky and coral reefs. They usually stay in waters that are not deeper than about 25 meters (82 feet).
Life Cycle and Habits
Reproduction
Queen parrotfish are special because they are protogynous hermaphrodites. This means they are born female and can change into males later in life.
They often live in small groups of about four or five fish. These groups usually have one large male and several smaller fish, which are likely females. When it's time to mate, the male swims in circles around a female. If she is ready, she will join him, and they will swim together in circles. At the same time, they release their eggs and sperm into the water. After the eggs are fertilized, they hatch. The tiny baby fish then float in the ocean as part of the plankton.
What They Eat
The queen parrotfish mainly eats algae. They scrape this plant-like growth off rocks and coral reefs with their strong beaks. They might also eat sponges and other small creatures stuck to surfaces. As they eat, they swallow tiny bits of rock and coral. These bits are later released as fine sand on the seabed. This process helps create the beautiful white sand beaches you see!
Nighttime Habits and Predators
Queen parrotfish are active during the day. At night, they rest on the seabed or hide in a small cave or crack in the reef. While they sleep, they create a special layer of mucus around themselves. This slimy layer might help hide their smell from animals that want to eat them.
Some animals that hunt and eat queen parrotfish include sharks, groupers, and eels.
How They Shape Reefs
Parrotfish are known for how they affect coral reefs. They cause something called bioerosion. This means they help break down hard materials like coral.
The queen parrotfish is known as a "scraper." This means it scrapes off the surface of corals to get its food. While it does cause some erosion, it's not as much as another type of parrotfish called the stoplight parrotfish, which is an "excavator" and digs deeper into the coral. Both types of parrotfish have very strong jaws and muscles. Large queen parrotfish can still cause a lot of damage to corals when they scrape off their food.
