The world of amphibians
The most poisonous frog is the bright-yellow poison-dart frog.^139
A choice of home
Frogs and toads can
live both on land
and in water.
Some even
live in trees.
Water living
Some salamanders
spend the whole of
their lives underwater.
This cave salamander does not
have any lungs; it breathes through its
skin only. It is almost completely blind.Caecilians
Legless caecilians are rarely seen by
humans because they live either under
water or under ground. They have a
pointed head, which they use as a shovel.
Travelling parents
Each spring salamanders,
newts, frogs, and toads
lay their eggs in ponds
or streams. Some travel
5 km (3 miles) to get there.
Land frogs tend to
be more rounded
in shape than
water frogs.
If an animal is poisonous like this tomato frog, it
is often a very bright colour that warns predators.
