Most anuran, especially males, are quite vocal. As the animal forces air from
the lungs, vocal cords in the voice box, or larynx, vibrate to make the distinctive calls to
attract a mate. The tongue of anuran is attached at the front of the mouth instead of
the rear and is covered with a sticky substance, making it an efficient trap for pray. It
Also produces mucus to help in swallowing. Although they cannot chew, most anuran
have teeth, which are used to grasp prey. All frogs and toads blink when they swallow.
Since no bone exists between the eye and the mouth, the eye is pushed against the
roof of the mouth, forcing the food farther back.
