Scarus frenatus, commonly known as the bridled undefined or the six-banded undefined, is an intriguing species characterized by its vibrant color patterns and key role in marine ecosystems. This undefined can grow up to 47 cm in length and undergoes notable changes in appearance throughout its life. In its early stages, it exhibits a reddish-brown hue with six to seven dark horizontal stripes and red fins. As males mature, the back of their bodies and the lower half of their heads transform to a lighter shade, and their caudal fins display a striking blue-green color accented with a large, orange crescent shape.
The natural habitat of Scarus frenatus spans the vast Indo-Pacific region, stretching from the 🌊 Red Sea to the Line Islands and Ducie Island. Its range extends northward to southern 🇯🇵 Japan and southward to places like Shark Bay in Western Australia, Lord Howe Island, and Rapa Iti in 🇵🇫 French Polynesia, though it is notably absent from Hawaiian waters.
Typically found at depths ranging from 1 to 25 meters, the bridled undefined prefers exposed outer reefs but can occasionally be seen in extremely shallow waters. Juvenile fish often inhabit lagoon areas, living among the rubble and coral of the reefs. Generally, these fish are solitary, although they may join schools with other species while feeding. Scarus frenatus primarily grazes on algae in the benthic zone, playing a crucial role in maintaining the health of coral reef ecosystems by controlling algae growth. Through their feeding habits, these undefined contribute significantly to the ecological balance of their marine environment.
