Characteristic Of Frog.

About Frog...
            The frogs are some of the few remaining members of the amphibia, a group which flourished 250 million years ago. Other present-day members of the group are the toads, newts and salamanders. The amphibia are adapted, in general, to moving, feeding and breathing on land as well as in fresh water. At certain times of their life history or at particular seasons, however, they show a dependence on, or preference for one or the other.
          Frogs have very good eyesight. They bulge out the sides of their heads in order for the frog to see in nearly all directions. Frogs also have amazing sense of hearing. You can often tell the difference between a male and female frog by the size of their eardrum, which can be seen behind their eyes. If the eardrum is smaller than the eye, the frog is a female. On males their eardrum is the same size as the eye. Frogs have very powerful back legs and webbed feet that help them jump great distances, as well as, swim. Frogs even use their legs to dig, or burrow, underground for hibernating. Certain frogs can jump up to 20 times their own body length in a single leap. Every different species of frog has his or her own look. They come in many colors, patterns and sizes.
This is the life cycle of frogs begins with fertilization, thebeggs, the cell spilts, the embryo, the tadpole begin  change to frog..
