Earliest known
amphibians evolved
from the lobe-finned
fish 400 million years
ago.
The lobe-finned fish had
strong fins the
eventually turned into
legs.
Their skull is very
similar to the earliest
amphibians.

Live in the water most of the
time when they are young, and
on land most of the time as
adults.
Cold-blooded
Can breathe through their skin.
This is called osmosis.
No teeth.
Some have sticky tongues or no
tongues.
They have glands that produce
a slimy mucus to help them
conserve moisture and prevent
too much water from being
absorbed into the body.

Most amphibians are best
kept in a rectangular
aquarium.
Tadpoles and amphibians
who live mostly in water will
need a aquatic habitat.
Amphibians that live on both
water and land will need a
semi aquatic habitat.
Amphibians that live mostly
on land will need a
woodland habitat.
The temperature of the
aquarium will depend on the
specie.

Breed in the water
Eggs attach to plants in

The eggs hatch into
tadpoles.
Tadpoles go through
metamorphosis in which
they develop legs, eyelids,
jaws, and lungs. They lose
their tails.

NEWTS

Most breed in the water.
The babies look like a
