Frogs can be as small as 0.4 inches and as large as 12 inches. Male frogs are usually smaller than the female frogs. Frogs, in some form, have roamed the earth for 190 million years and have looked much the same throughout history. Interesting Frog Facts Frogs have endured throughout history with an uncanny ability to adapt to their surroundings. They can be found on every continent, except Antarctica, and are most at home near freshwater and in warm tropical climates.
Frogs typically breed in freshwater.
The eggs, laid in clusters of hundreds and sometimes thousands, attach to the stems of water plants. The tadpole hatches in a few days to a week or more and will develop into a frog within two months to three years. During metamorphosis, the lungs develop, limbs appear, the tail is absorbed, and the mouth becomes typically froglike. In some Oriental species the eggs are deposited on land and the young hatch as froglets, not tadpoles. Many frogs can leap up to twenty times their body length.
