Approximately 4,740 species of frogs exist across the globe. Frogs are found in every continent of the world except for Antarctica. The highest concentrations of frogs are found in warm, wet, tropical climates.

Frogs and toads belong to the Anura order in the class of amphibians. The word "amphibian" comes from the Greek and means "both lives." The majority of frogs are born in the water and live the first part of their lives as aquatic tadpoles. As they mature, they lose their tails and gain the legs that let them exist on land as well as in the water.
