About Thalassoma lunare (Linnaeus, 1758)
This species, scientifically named Thalassoma lunare (Linnaeus, 1758), has distinct appearance changes as it matures. Juveniles have a blue lower body half, a black spot in the center of the dorsal fin, and a black blotch at the base of the caudal fin. As the fish matures, the original black spot on the dorsal fin develops into a yellow crescent shape, which is where the species gets its common name. Mature adults have green bodies with prominently marked scales. Their head coloration ranges from blue to magenta, and displays a broken checkerboard pattern.
