Four Stages of Frog Development

• Fertilized eggs in a mass called a Spawn
• Tadpoles hatch from the eggs
• The tadpoles then develop into Froglets
• Adult Frog

3
Adult Frog

• Amphibian
• Smooth skin, long jumping legs, squatty front
  legs, and webbed feet.
• They live near the water and eat insects.
• There are over 4000 species of frogs identified.

4
Spawn!

• The female adult frog lays a mass of eggs (around
  10,000) that are fertilized by the male frog
• This mass of eggs is called the spawn
• Inside each of these little eggs a tadpole is
  developing

Tadpoles

• The water dwelling stage of this amphibian
• The tadpoles have a small oval body, gills for
  breathing underwater, and long tail with fins on
  upper and lower parts of the tail for swimming.
• These tadpoles will eventually lose the tail and
  gills and become an adult frog.

6
Froglets

• This is the short stage between the tadpole and
  the adult frog.
• This is the point where the frog will first be
  able to leave the water and breath air.
• Once the froglet leaves the water it will take
  about three years before that frog will mate and
  start the cycle all over again.

Now we will do a small activity to see if you can
determine the different stages of the the frogs.

  piece of paper from 1 - 4 write down your answers
  there.
