A young Amazon Forest Dragon (Enyalioides laticeps) poised on a branch
These arboreal lizards are fairly common in the Amazon rainforest. In my experience, they are much easier to find at night, sleeping on branches both horizontal and vertical. I've been to this part of Peru twice and seen a dozen or so of these lizards, but this was the only one I saw during the day. (A local guide spotted this one.)
The Amazon wood lizard , also known as Guichenot's Dwarf Iguana is a species of reptile in the genus Enyalioides, native to the western part of the Amazon basin, notably in Colombia, Ecuador, Brazil, and Peru.
