@FelipeDBKO Unfortunately, I haven't. For what I know, she's still off display, and an exhibit is still being built for her. I saw a building that was very much the kind of an armadillo exhibit.
@Therabu Yes, the black caimans in the zoo have free access to this entire water area. It's actually a big lake that, besides caimans, has some small primate islands, some capybaras, and some species of chelonians, such as a huge Podocnemis expansa that I was able to spot. All of them living together, and there are ramps, such as the one in the picture, to provide access for all the animals to the primate islands.
About the size, the individual in the picture surely measured at least 3 meters; good size for an adult black caiman I think...
