Suriname toad, Inírida, Colombia
This is a personal favorite, an unexpected jewel of a species we found as we were struggling the path of a dense forest in the pitch black night. In this flooded forest, dead leafs fall in the water, covering the floor. But one of these leafs is not dead, instead it's a bizarre type of amphibian called the Suriname Toad.
It is remarkable in its appearance which is almost as flat as a leaf. To support the ability to be this flat, it has no tongue or teeth. An even more mind-blowing fact about this species is that females develop their young directly inside the skin of their own back, shown in this video:

PS: we poked it slightly with a small twig, and it very much was alive.
