Diets of Amazonian crocodilians
Caiman crocodilus, Melanosuchus niger and Paleosuchus palpebrosus, which occur around rivers and lakes, have similar diets: small individuals eat invertebrates and large individuals eat invertebrates and fish. Juvenile Paleosuchus trigonatus, which live in small forest streams, eat larger numbers of...
