Green Iguana, GuyanaGreen iguanas are strong climbers that spend much of their lives in trees, often choosing branches that overhang rivers and streams. If threatened, they can plunge into the water below and swim away with surprising speed, using their powerful tails to propel themselves through the current. This one, as you can see, had a little nip taken out of that tail. Nikon Z8 with Nikkor 500mm PF lens, ISO 6400, f/5.6 at 1/250th of a second.
