Frog vs Toad
Frogs and toads have several similarities which include the look and structure but there are certain differences also. Both toads and frogs have two lives, the aquatic larval stage called tadpole and the semi-aquatic or terrestrial adult stage. So both of them are amphibians and belong to class vertebrates. Both of them reproduce in a water body. Both frogs and toads have skin gland with a bad flavor but the secretions are stronger in toads. Frogs are eaten by a large number of predators. Both toads and frogs have a life span of thirty to forty years. Both of them can close their mouth and nasal opening and they force air from lungs to mouth. Then they force the air back through the vocal chords in to the lungs to make a sound. This ability of these animals helps them to vocalize under water.

One of the major differences between them are toads have dry and warty skin whereas frogs have wet and smooth skin. Frogs are the members of the family Ranidae that consists of more than 400 species. Both upper and lower jaws of frogs consist of tiny teeth. The hind legs of frogs are longer than the toads and frogs can be differentiated from toads by the presence of webbed back feet. The eyes of frogs are protuberant. Frogs jump whereas toads hop. Frogs will jump far to escape from a predator. Female frogs lay eggs as single, small or large clumps on the surface of the water. Frogs are light brownish green in color which is helpful for them to stay camouflaged at the bottom of ponds or damp leaves. Some frogs are poisonous; one example is South America’s poison dart frog. Frogs are found every where except in Antarctica.

Toads are the members of the family Bufonidae with over 300 species. Toads are found in temperate regions. They are brown and olive in color whereas those found in tropics are brighter in color. Toads have a short body than the frogs and the legs of toads are stubby and muscular. Eyes of toads are more recessed than the frogs. Toads lack any kind of teeth. Female toads lay eggs in long and parallel strings on the surface of water. Toads cannot jump as fast as the frogs. Because of this they produce toxic and unpleasant skin secretions which are released when the animal is attacked. The unpleasant taste and odor of the toads make them unpopular prey among the predators. The eggs and tadpoles of toads are also toxic. Poison sacs are located behind the eyes of toad. Toads can be found worldwide except in Madagascar, Polynesia, Polar Regions and Australia.
