Moon wrasse

Thalassoma lunare


Its length is up to 30 centimeters, although they tend to average about 25. Juveniles are blue on the lower half of the body. They have a black spot in the middle of the dorsal fin and a black blotch on the caudal fin base. As they mature, the spot turns into a yellow crescent, hence the name. The body is green, with prominently marked scales. Coloration of the head ranges from blue to magenta, with a broken checkerboard pattern.


MacKay Reef, Great Barrier Reef, Queensland.


This fish is in the lower left-hand corner of the first photo. Any ideas on the blue-spotted fish, anyone?
