Life Cycle of a Frog
The male frog fertilizes the eggs as they get are laid. Frogs
tend to lay eggs in masses, whereas toads usually lay eggs in long
chains. Bullfrogs lay eggs in a giant floating raft. The eggs taste
terrible so other animals will not eat them. Some of the adult frogs
leave after this point, but others stick around to watch over the little
ones. Some have very unusual
ways of caring for their young such as caring for them while in their
and Toads tend to lay many eggs because there are numerous hazards
between fertilization and full grown frogs! Those eggs that die tend to
turn white or opaque. The lucky ones that actually manage to hatch still
start out on a journey of many perils.
Shortly after hatching, the tadpole still feeds on the remaining yolk,
which is actually in its gut! The tadpole at this point consists of
poorly developed gills, a mouth, and a tail. It is very fragile at this
point. They usually will stick themselves to floating weeds or grasses
in the water using little sticky organs between itís' mouth and belly
area. In 7 to 10 days, it will begin to swim around and feed on algae.
Tadpole with legs
After about 6 to 9 weeks, tiny legs start to sprout. The head becomes
more distinct and the body elongates. By now the diet may include larger
items like dead insects and even plants.
Young Frog or Froglet
By 12 weeks, the tadpole has only a small tail stub and looks like a miniature version of the adult frog. Soon, it will leave the water.
By between 12 to 16 weeks, depending on water and food supply, the frogs complete their full growth cycle. Some frogs that live in higher altitudes or in colder places might take a whole winter to go through the tadpole stage. These frogs will start the whole process again, finding mates and creating new frogs.
