Frog, Bullfrog, or Toad?
At first glance, frogs, bullfrogs, and toads look very much alike, but each has its own identifying physical characteristics. Here’s how to tell them apart.
Frogs have folds of skin called dorsolateral ridges that begin at the eye and go around the eardrum, ending at the front legs. A frog’s dorsolateral ridge also runs along the back. Frogs have a smooth, moist skin.
Bullfrogs have dorsolateral ridges too, but only the folds of skin begining at the eye and going around the eardrum, ending at the front legs. Bullfrogs do not have a dorsolateral ridge along the back like frogs do. Bullfrogs also have a smooth, moist skin.
Toads have a dry skin that is covered with warts. They also have large swellings behind the eyes called paratoid glands and raised ridges on the back of the head called cranial crests. They do not have the dorsolateral ridges that frogs and bullfrogs both have.
