Prey and predator and vice-versa

If people ask what's a caiman's (Caiman crocodilus yacare, jacaré-do-pantanal) predator we would say: "well, maybe, sometimes, ahh, uuhh, a jaguar (Panthera onca) or an anaconda (Eunectes notaeus, sucuri-amarela) and nut much more ...", but in fact, we forget that they hatch as little vulnerable creatures and are heavily predated at this stage of life. Even rufescent tiger-herons (Tigrisoma lineatum , socó-boi) feed on young caimans.
And then they grow and grow and soon they will be hunting fish and birds like tiger-herons !
