This photo might prompt you to ask "what's wrong with this animal?" This turtle is just taking a rest. Apparently, swimming in the surf and eating green algae is tough work. Who knew? During the trip, we got to swim with many of these huge turtles (not to be confused with Galapagos land tortoises). This species is not endemic to the Galapagos archepelago and can be found throughout the Pacific in places such as Hawaii.
