Transcript The Life Cycle Of The Frog

Eggs
Frog eggs are found in wet
places.this floating clump of
eggs is called a spawn and can
be up to Several thousand.
These big clumps of eggs are to
big too be eaten.but the smaller
ones can be eaten by creatures
that live on and by the pond.
The eggs become surrounded
by jelly covering,witch also
helps protect the egg.
Sometimes females stay with
the eggs to take care of them.
Embryo
This single cell splits
in two and in two
again making four
Cells and so
on.Eventually there
are many cells in
the eggs.these eggs
form an embryo.this
is when it begins to
form.Its food supply
is the yolk which
lasts 21 days.
Tadpole
Soon after hatching the tadpole
is still feeding on the yolk, watch
is in its gut. The tadpole has
poorly developed gills, mouth,
and tail. This fragile Tadpole will
stick to eating floating weeds
and grasses.
7-10 days later the tadpole will
start swimming around to eat
algae.
4 weeks later the skin stats
growing over the gills until they
disappear. The Tad poles get
teeny teeth witch grind food.
There guts are coiled witch
helps them digest nutrients from
their food as possible. On the
fourth week tadpoles are quit
sociable some even travel with
schools of fish.
Tadpole with legs
After about 6 to 9 weeks,
little tiny legs start to sprout.
The head becomes more
distinct and the body
elongates. By now the diet
may grow to include larger
items like dead insects and
even plants.
The arms will begin to bulge
where they will eventually
pop out, elbow first.
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 full grown!
Underdeveloped Pollywog
The tad pole is
nearly fully
grown by week
twelve. He only
has a tail of a
difference. After
she leaves the
water hey will
only return
again to lay
more eggs
Pollywog
After 11 weeks
the tadpole grows
to look more like
a frog it stops
using its tail and
starts using its
legs to swim. The
Pollywog can
soon go upon
land. Some times
the Pollywog
sleeps in water
with only its nose
sticking out
Frog
After 12-16 weeks
depending on water the
frog has completely
developed. If frogs live
in cold places or higher
altitudes this might take
all winter. Soon the
frogs will start the whole
process again, finding
new mates and creating
new frogs
Conclusion
The frog has a very
interesting life
cycle.
The frog life cycle
has 7 different
even stages if you
count the three
stages as one.
