Green sea turtle & chameleon wrasse

Galapagos Islands are very good not only to see land tortoises but also to spot green sea turtles. They are very docile and can be found in the moment you venture in the water, even snorqueling.
Here, just by chance, a chameleon wrasse crossed by in the moment the picture of the turtle was taken. The chameleon wrasse is very colorful:

Ground color has 2 distinct phases, reddish or greenish, which can be interchanged quickly; initial phase primarily pinkish or greenish above and white below; terminal phase with blue stripes on head and blue stripes or horizontal rows of blue spots on side, usually a prominent bluish-black spot on lateral line below anterior part of dorsal fin; juveniles greenish on upper half with white midlateral stripe, whitish below, and with small black spot at midbase of caudal fin. Size: reaches 25 cm.
