The diet of young crocodiles is made up largely of insects and other invertebrates, since this is the only prey the same animals can easily take. More than 100 species and genera of insects were identified among the food of crocodiles of this age. Of the insects taken there, beetles made up 58% of the diet, including Hydrophilus and Cybister.

Compared to crocodiles, alligators digest more carbohydrates relative to protein. [107] Crocodilians have a very low metabolic rate and thus low energy requirements. They can withstand extended fasting by living on stored fat. Even recently hatched crocodiles are able to survive 58 days without food, losing 23% of their bodyweight during this ...
