Tiny frogs, or baby frogs, generally eat small insects, including spiders, beetles, grasshoppers, flies and crickets. They also eat forest mites and very small invertebrates such as slugs, snails and worms.
Frogs have a sticky tongue that they fling towards their pray to catch them. Even tiny frogs have tongues that are so sticky that moving prey will latch onto it and stay stuck. It takes less than one second for frogs of all sizes to roll out their tongues, so whatever prey the frog is trying to catch will have no time to attempt an escape. Frogs have small maxillary teeth that they can use to hold their food in place before swallowing, but these teeth are not strong enough for tearing or chewing, which is why frogs swallow their entire meals whole. Frogs are quite active when it comes to stalking their prey. They use their camouflage skills in order to lay undetected, and as soon as their unsuspecting prey passes by, they strike.
Baby frogs that are kept as pets often eat dead or live bugs that are purchased from local pet stores. Pet frogs can also eat worms, crickets and other insects that owners gather from outdoors. To ensure a pet frog's health, owners should never feed it bugs that have been sprayed with insecticides.
