Baby toads, called tadpoles, eat plants. As they grow into adults, toads diversify their diets and begin to eat insects, slugs, grubs, worms, and other invertebrates, just as most amphibians do.
Since they eat insects, toads that live outside in the wild are very useful for their services in controlling pests. Thus, gardeners benefit greatly from having toads inhabit their gardens.
If kept as pets, toads can eat fruits and vegetables, in addition to insects.
Unlike frogs, toads do not have teeth. In order to catch its prey, a toad must flick its tongue forward from its mouth and catch the food with the sticky part of its tongue.
