The Tucuxi (Sotolia fluviatalis) is one of a handful of dolphins living throughout the Amazon River complex. This is not the more famous Boto (Pink River Dolphin), but is often found swimming in groups alongside them. This was one of a few in such a mixed group, surfacing here and there with some larger Boto […]

They eat lizards and other snakes, and the occasional frog, rodent, and bird. Usually when they’re seen, it’s moving through leaf litter on the ground as […]

My favorite crocodilian, the Smooth-Fronted Caiman. These little guys live in smaller streams and hills in the rainforest, and have a lot of attitude for such a little guy.
