What's the difference between a frog and a toad? Frogs usually have smooth, moist skin and spend most of their lives in or near water. Toads usually have dry, warty-looking skin and spend more time living on land.
Scientifically, things are a more complicated. Besides the true frogs (Ranidae) and toads (Bufonidae), there are separate families for tree frogs, spadefoot toads, poison-arrow frogs, and several other groups. The order that contains all the frogs and toads is called Salientia (from a Latin word that means "leaping") or Anura ("tailless").
