Frogs have a very interesting anatomy. They have highly specialized structures, such as a long, sticky tongue.

They also have other structures however, that appear useless. Their weak teeth are an example of this.

Frogs breathe through their skin when underwater. They also have a pair of lungs that allow them to breathe on land.

Frogs have a three-chambered heart and a vertebral column that consists of nine vertebrae.
