The Frog Has Teeth.
Put your finger in a frog’s mouth and you can distinctly feel a number of fine, sharp teeth, but if you put your finger in a toad’s mouth you will find no teeth; a frog grabs his prey with his jaws, a toad snips it up with his tongue.
Besides the common, funny old hop-toad, there are the Rocky Mountain hop-toads, the Southern hop-toads, and the hop-toads from Northeastern Massachusetts, which differ sufficiently from the common hop-toad to be classed by naturalists as sub-species.
