Amphibians are vertebrate
animals.They live depending on the
water or on land in different climates.
Some emigrate. The body of the
amphibians has no protective covering,
when they are young they have gills and
a tail, when they grow older, they
develop lungs and legs

3. Amphibians
They are oviparous, the mother doesn’t
take care of the babies. There are two
groups of amphibians: whith tail very
long body and short legs and the other
group ,without tail, whith short body
and the front legs very strong and
bigger.

are covered whit scales, they breath
through gills and they have fins to move
about. They are oviparous, they hatch
form eggs; baby fish are called fry.
Cartilaginous fish have the skeleton
made of cartilage (ex rays for
example)bony fish’s skeleton is made of
bone (sardines, tuna).

climates and some emigrate. Their body
is covered by feathers, they breath
through lungs, they have wings and legs
to move about. Most fly. They are
oviparous ,the mothers don’t take care
of the babies. Groups: runners,
swimming birds, birds of prey,
nocturnial birds, etc.

10. Reptiles
They are terrestrial and aquatic ,but
they all breath with lungs so they have
to go out of the water to take oxygen
.They are covered with scales, most
have legs to move about, some need the
sun to maintain their bodies temperature
.For this reason, they are called cold
blooded animals. They are oviparous.

nurture or care for their young. Eating
habits: most reptiles are carnivorous
and capture live prey.
