A general term for frogs of the Ranidae family. In general, it often refers to red-bodied frogs such as the Japanese brown frog and mountain brown frog. The Ranidae family is a group with typical frog shapes such as the Japanese brown frog, Japanese brown frog, and marsh frog, and there are about 44 genera and 625 species distributed throughout the world, but there are few species in Australia and South America. Most are terrestrial, living in grasslands or forests near water. They have excellent jumping ability and, as can be seen in the Japanese brown frog, they hide in grasslands where they can escape into the water in one leap.
