Uakari Lodge floats in a tributary of the Amazon river, rising and falling dozens of feet seasonally with the water level. It's disconnected from the shore, so you might think that it would be a lizard-free environment. Fortunately, you'd be wrong. A colony of these whiptail lizards was living the good life on the wooden planks and potted plants of the lodge.

The Mamiraú guidebook lists K. altamazonica but no other Kentropyx species. However, K. altamazonica generally has a straight-edged bright green stripe starting on the head and fading down the back. These lizards had a wavy-edged stripe when young, and no significant stripe at all as adults. I believe these to be K. pelviceps, but maybe they are some other small teiid species. If you know better, please correct me.

Here is an account of the four days we spent at Uakari Floating Lodge in the Mamirauá Sustainable Development Reserve.

This was the only whiptail I saw in the actual forest, as opposed to on the grounds of the floating lodge. It's a young adult, not as large as the adults I saw on the floating lodge, but also not as small as the youngsters there.

Speaking of the youngsters on the lodge, here's one from the next day, showing off its youthful colors.
