About Starspotted Grouper

The Starspotted Grouper exhibits a dark gray to brownish body covered with distinctive bright white or pale yellow spots arranged in a hexagonal pattern—the defining feature giving the species its name. The body is robust and compressed laterally with a slightly rounded head. These spots persist throughout the fish's life and become more prominent under certain lighting conditions.
