For the last century, crocodilians have been kept successfully in zoological collections. There were some zoos, such as Berlin's zoo-aquarium and the Berlin Tierpark, that kept multiple species in one exhibit. These two zoos now keep their crocodilians in different enclosures. So my questions are: - Is it recommendable to keep certain crocodiles and alligators together? - Is it better for the public to see more than one crocodilian species in one enclosure? - Do any modern zoological collections practice that model? As of now, I believe that mild-mannered crocodilians could possibly be kept together. For example, I could see a mixed enclosure of spectacled caiman and Orinoco crocodile working fine. As for the public, it may be a hot enough idea; in different enclosures, many uncouth people just generalize, or don't care about what they are. But if two different-looking species lived in the same place, I think some questions would be raised, and they'd actually look at the sign. What are your thoughts? I'd like to know.
