There are over 5,000 species of frogs in the world. The most common frog groups include treefrogs, toads, and true frogs. Treefrogs have smooth skin and live in trees, while toads have warty skin and live in water. True frogs have dry, wart-free skin and live on land or in water. Other frog groups include caecilians (wormlike amphibians), salamanders (newt-like amphibians), and gymnophionans (frog-like amphibians).
