Photo by @mattiasklumofficial for @natgeo Marine iguana, Galapagos, warming up after a chilly dive. Go to @mattiasklumofficial to see these remarkable lizards posing like statues waiting for the night. They are sometimes dangerously cold after grazing algae at dephts down to 30 or more feet. #galapagos #marineiguana #conservation #iucn #wwf @natgeo @thephotosociety
