Young Crocodile Tegu (Crocodilurus amazonicus) resting on a branch

I spotted this colorful lizard from a kayak, and it held still just long enough for me and a friend to get photos from this distance. We then tried to move in a little closer and it slipped off the branch and disappeared into the river. The babies of this species are very strongly patterned with bright colors. Adults lose the pattern and become a uniform dark green. This one is young, but still not as beautifully patterned as the even younger ones.
