Here are a few picture I took while in Peru a few years ago(I think I actually posted here when I got back to confirm a caiman species). I was in a very remote area that was virtually never accessed by humans and had very high populations of black caiman. Some nights I would go out in a dugout canoe and catch black caiman and other nights I would walk streams and flooded rainforest to catch spectacled caiman. What was very interesting is that you don't find large spectacled caiman in the streams or flooded forest, but you do find large numbers of smaller ones. Large spectacled caimans are commonly seen in the rivers. Black caiman prefer living in the oxbow lakes, and you generally don't find them of any size in the streams or rivers. Anyway, I thought you guys would appreciate these photos! By the way, the "roar" of a full grown black caiman is one of the loudest, most frightening things you will ever hear.
