Princess Parrotfish
Scarus taeniopterusAlso known as Painted-tail Parrotfish
Princess parrotfish are vibrant reef residents that undergo dramatic color changes as they mature, transitioning from striped juveniles to brilliant blue-green terminal phase males. During the day, they scrape algae from coral skeletons using their fused, beak-like teeth, playing a vital role in preventing algae from smothering the reef. At night, they spin a protective mucus cocoon to mask their scent from predators while they sleep in reef crevices.

LC
Safe to observe at a normal distance.
- Listen closely: You can often hear their distinct crunching sounds underwater as they scrape algae off the coral.

- Look for sand: Watch behind them to see them excrete fine white sand, a direct byproduct of their feeding.
