Photo of Animalia: Green Moon Wrasse (species: Thalassoma lutescens) (Lizard Island Field Guide)

Thalassoma lutescens on the outer slope of Number 10 Ribbon Reef near Lizard Island. Note the yellow/green pectoral fin with dark blue edge which is useful in the field to distinguish this species from the similar and much more common Thalassoma lunare.
