    • All About Frogs!
      By Mary Miller
    • My Favorite Animal is a Frog!
    • Frogs are Amphibians
      Amphibian means “on both sides of life”
    • What do amphibians have in common?
      They live on land and in water
      They breathe water when they are young and
      either grow gills OR breathe air when they are older
      They are cold-blooded
      Many lay their eggs in water
      Most live in fresh water
      About 88% of amphibians are frogs
    • What do Frogs Look Like?
      • Have a short body
      • Webbed fingers or toes
      • Protruding eyes
      • NO tail
      • Are excellent jumpers
      • Start out as tadpoles
    • Where Do Frogs Live?
      All over the world (see black on map)
      Most species live in the rainforest
      They do NOT live in Antarctica and some oceanic islands
    • Camouflage
      Is common in frogs
      Most with camoflage are nocturnal
      awake at night
      this helps them hide
      Some can change colors
      only two colors
    • Poison
      Many frogs have toxins so other animals will not eat them; they taste bad
      Some frogs are very poisonous
      They usually have bright colors
      Some frogs get their poison from the animals they eat (e.g., ants)
    • Eating
      Frogs have teeth used to grind food
      Frogs have a sticky tongue
      Use it to catch food
      Most eat flies and insects
      Some large frogs eat small mammals, fish, and smaller frogs
      Very few eat just plants
    • Life Cycle
      2. Tadpole (or Polliwog)
      1. Egg – most female frogs lay eggs in early spring
      4. Adult
      3. Metamorphosis
      Captive frogs and toads can live up to 40 years
    • Frog Calls and Croaks
      Some are so loud they can be heard a mile away
      Many have deep calls or croaks
      They call by passing air through their throat
      The main reason they call is so males can attract females
      Other reasons are to guard territory, to forecast rain, and when under stress (if a predator is near)
    • Famous Frogs
      Frogs are used a lot in books, movies, commercials and cartoons!
