COMPOSITION OF FROG
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.
