All toads are frogs, but not all frogs are toads. While both belong to the order Anura, toads are actually a subset of frogs. They can usually be identified by appearance, but there are some frogs that appear dry and bumpy, and many toads can trick you by looking wet and slimy. When in doubt, just call it a ‘frog,’ and you’ll always be correct. Source Source 2 Source 3
