Amphibians are animals
that live PARTLY in water
and PARTLY on land.
Frogs, toads, NEWTS, and
salamanders are all
amphibians.
REPTILES have dry, scaly
skin, but AMPHIBIANS
have soft, moist skin. Most
amphibians can breathe through
their skin, but only if it stays
damp. Adult amphibians can
also BREATHE
through lungs.
Most
amphibians
breed in water
Unlike reptiles, which lay
.
tough-shelled eggs on
land, most amphibians
lay soft, jellylike eggs
in water.
Most frogs live near a river
or pools of water. But in
rainforests, it is so humid
the trees are wet all the time,
allowing some frogs to stay
in them permanently. They
are called tree frogs and have
huge, sticky fingers to help
them climb.
Most baby amphibians live entirely in water.
Called tadpoles, they swim like fish and
breathe through gills. As they grow up, they
develop legs and crawl onto land, but they
must always be in wet places.
When a tadpole
hatches out of an egg,
its first task in life is to
eat what’s left of its egg,
which is full of nutrients.
In most amphibians, the
tadpole changes into an
adult by a process called
metamorphosis
