3. FROG SPAWN
Frogs lay so many eggs. From
the three thousand eggs that
one female lays, only around
five will become adult frogs.
The rest of the eggs or
tadpoles may be eaten by
birds, fish, newts, water
beetles, dragonflies or simply
dry up before hatching.
The frogspawn that you see
floating in ponds is made up
of thousands of single
eggs, each one having a
tiny black tadpole embryo
surrounded in jelly.
4. TADPOLES
Immediately after
hatching, they will usually
stick themselves to weeds or
grasses in the water. After
about seven to ten days, the
tadpoles will start swimming
around and feeding on
algae. After about six to nine
weeks, the tadpoles start to
absorb their tails and grow
legs and arms. Now the
tadpoles will eat plants and
dead insects floating on the
water.
