Crocodylus acutus
There are several records of American crocodiles killing and eating spectacled caimans in South America. Areas with healthy American crocodile populations often hold only limited numbers of spectacled caimans, while conversely areas that formerly held American crocodiles but where they are now heavily depleted or are locally extinct show a growth of caiman numbers, due to less competition as well as predation. In areas of Cuba where the two species coexist, the smaller but more aggressive Cuban crocodile is behaviorally dominant over the larger American crocodile. In Mexico, some Morelet's crocodile individuals have escaped from captivity, establishing feral populations and creating a problem for the populations of American crocodile, which must compete with this invasive species.
