Crocodiles are carnivorous predators whose diets shift significantly as they grow from hatchlings to adults.12

Early Life

In the first weeks and months of life, young crocodiles and hatchlings consume small prey items. Their diet typically includes:
* Invertebrates: Insects, crustaceans, and snails.13
* Small vertebrates: Small fishes, frogs, and tadpoles.13

Adulthood

As crocodiles grow larger, they transition to a broader diet consisting of larger prey. While their specific intake can vary by species and environment, adult crocodiles generally consume:
* Fish: A primary food source for many older individuals.1
* Waterfowl and Mammals: They frequently prey upon various birds and mammals.13
* Other Vertebrates: Depending on the species, they may also eat turtles and other animals.3

While some of the largest species have been known to attack humans, such incidents are rare and do not characterize crocodiles as general man-eaters. Crocodiles are opportunistic hunters that use their powerful jaws and specialized pressure receptors to capture prey in both aquatic and terrestrial environments.12
