The feeding strategies of amphibians include their choice of prey and the ways they locate, capture, and eat the prey. All adult amphibians are carnivores. They feed mostly on insects and, but some eat a wide variety of invertebrates. As amphibians grow larger, the kinds of prey they select may change. As larvae develop teeth, they capture larger prey.
Hylid frogs eat increasingly larger preys, even during postmetamorphosis.
The diet of anurans living in West Africa vary greatly throughout the year. Among the thirteen species of anurans living in Amazonian Peru, the difference in food was greatest during the dry season. These differences are indications of the availability of prey. Some animals are dormant during the dry season. In some amphibians, the selection of larger prey is likely when moisture conditions are heavy.
