Question

How are toads adapted to pond life?

Answer 1

Frogs start their lives as aquatic tadpoles with gills to breathe. As tadpoles grow into frogs, lungs replace the gills and allow frogs to breathe on land. Frogs' skin is covered by a layer of slime that dissolves oxygen from air and water. Numerous blood vessels present in frogs' thin skin absorb the oxygen.

Answer 2

To start calling, a frog breathes in and then closes its nostrils. It forces the air backward and forward between its lungs and vocal sac, so that its vocal cords can make the air vibrate. Male frogs and toads have a distinctive mating call, which attracts females of the same species.
