Life Cycle of Frogs

TEKS§ 112. Science, Grade 1 10) Organisms and environments. The student knows that organisms resemble their parents and have structures and processes that help them survive within their environments. The student is expected to: Ø D) observe and record life cycles of animals such as a chicken, frog, or fish

STAGES Eggs Adult Froglets Tadpoles with legs

Eggs Usually, about 6 -21 days (average!) after being fertilized, the egg will hatch

Tadpole The tadpole at this point consists of poorly developed gills, a mouth, and a tail Then, 7 to 10 days after the tadpole has hatched, it will begin to swim around and feed on algae.

Tadpole with legs After about 6 to 9 weeks, little tiny legs start to sprout. The head becomes more distinct By now the diet may grow to include larger items like dead insects and even plants After about 9 weeks, the tadpole looks more like a teeny frog with a really long tail. It is now well on it's way to being almost fullgrown!

Froglet or young Frog By 12 weeks, the tadpole has only a teeny tail stub and looks like a miniature version of the adult frog. Soon, it will leave the water, only to return again to laymore eggs and start the process all over again!

Adult Frog By between 12 to 16 weeks, depending on water and food supply, the frog has completed the full growth cycle. Now these frogs will start the whole process again. . . finding mates and creating new froggies.
