Amazing facts about frogs
Frogs don't need to drink water as they absorb it through their skin. Some frogs can jump over 20 times their own body length; that is like a human jumping 30m. A frog's call is unique to its species, and some frog calls can be heard up to a mile away Amphibians comprises a large and diverse class of animals. The term "amphibia" represents both aquatic and terrestrial life amphibians, spending part of their lives in water as well as on land.
Amphibians, even though they appears to be soft and squishy, do have a mostly–bone skeleton and the the rest of the body is made of cartilage. The skin is almost moist and is permeable to water. It lacks scales on it, and can be smooth as frogs or bumpy as toads. Amphibians are in a wide variety of shapes, sizes and colors, and some of them are most poisonous vertebrates (arrow–point frogs).
The body of the frog is divisible into two regions, the head and the trunk. Frogs also have amazing sense of hearing. Behind and below the eye, on either side, there is a circular obliquely placed membrane, the eardrum or the tympanum. There is no external ear or pinna. The tympanum receives sound vibrations from the environment. In male frog, under the mouth, there is a pair of bluish patches of skin called vocal sacs. The vocal sacs help in croaking.
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. Thus, every different species of frog has his or her own look. They come in many colors, patterns and sizes.
