You are walking along a pond when you see a frog - or is it a toad? What's the difference? Frogs have smooth skin, and rely on their large, powerful legs. Also, frogs are slim, small, and streamlined. On the other hand, toads have warty skin. In contrast to frogs, toads are fat and slow moving. In addition to that, they also puff themselves up with air, unlike frogs. Although frogs and toads are different, they also have some similarities. Both frogs and toads are amphibians. They are also alike because they have lungs, but also breathe through their skin. Just like toads, frogs use sounds to attract their mates, and their diets consist of insects, worms and more. As you can see, frogs and toads are alike and different.
