2. Frog Characteristics  When we think of frogs, we generally picture what are called "True Frogs"....members of the family Ranidae, containing more than 400 species. These frogs have the characteristics of:  two bulging eyes  strong, long, webbed hind feet that are adapted for leaping and swimming  smooth or slimy skin (generally, frogs tend to like moister environments)  Frogs tend to lay eggs in clusters.

3. Toad Characteristics Toad Characteristics  The term toads tends to refer to "True Toads".... members of the family Bufonidae, containing more than 300 species. These types of frogs have are characterized by:  stubby bodies with short hind legs (for walking instead of hopping)  warty and dry skin (usually preferring dryer climates)  poison glands behind the eyes  The chest cartilage of toads is different also.  Toads tend to lay eggs in long chains.

4. Frog Life Cycle Frog Life Cycle  1 st : Egg-Tiny frog eggs are laid in masses in the water by a female frog. The eggs hatch into tadpoles  2 nd : Tadpole - (also called the polliwog) This stage hatches from the egg. The tadpole spends its time swimming in the water, eating and growing. Tadpoles breathe using gills and have a tail.  3 rd : Tadpole with legs - In this stage the tadpole sprouts legs (and then arms), has a longer body, and has a more distinct head. It still breathes using gills and has a tail.  4 th : Froglet - In this stage, the almost mature frog breathes with lungs and still has some of its tail  5 th : Adult - The adult frog breathes with lungs and has no tail (it has been absorbed by the body).

6. Some Frog Facts Some Frog Facts  Frogs absorb water through their skin so they don't need to drink.  Frogs can lay as many as 4,000 eggs in frogspawn.  The eyes and nose of a frog are on top of its head so it can breathe and see when most of its body is under the water.  Frogs need both water and land to live.  A frog can change the color of its skin depending on its surroundings.  Frogs have long back legs and webbed feet for jumping and swimming.  Certain frogs can jump up to 20 times their own body length in a single leap.  Frogs usually eat meat (bugs and worms) and swallow their food whole.  The world's biggest frog is the goliath frog from Cameroon in West Africa. Their body can be one-foot long.  The smallest frogs in the world are less than half-an-inch long.
