<human>: I've always wondered what the difference is between a frog and a toad.
<bot>: A frog is a member of the order Anura, while a toad is a member of the order Caudata. The distinction between these two groups of animals is based on their physical characteristics. Frogs are typically smaller than toads, with smooth skin, webbed feet, and no external gills or lungs. Toads have thicker skins, dryer tongues, and more developed lungs and gills.
