They also cling to grass blades and weed stalks near water's edge. All frog and toad males, regardless of species, have breeding voices they use to attract mates. To make their calls, male toads and frogs close their mouths and noses and force air back and forth from their lungs to their mouths. The air passes over the vocal cords and creates a distinct sound. Balloon-like voice sacs help amplify the sounds.
Some frogs can even call under water.
As amphibians, toads and frogs live part of their lives in water and part on land. When young, they live in water as tadpoles. As they mature, they grow legs, but their gills and tail disappear. They also develop lungs, allowing them to breathe air and spend most of their time on land. Frogs resemble toads, but there are essential differences.
