<human>: I'd like to know more about the different kinds of frogs.
<bot>: There are over 5,000 species of frogs in the world. Frogs can be divided into two main groups: tree frogs and ground frogs. Tree frogs have smooth skin, webbed feet, and live in trees or bushes. Ground frogs have warty skin, clawed toes, and live on the ground. There are also burrowing frogs, which live underground and use their powerful legs to dig tunnels.
