A feature that helps a living thing to survive is called an “adaptation”
e.g. thick fur in cold places.

Thick layer of fat and hollow oily fur.
Long eyelashes.
A short snout or nose.
Small ears and a very rounded body.
Claws and large, cup like feet.

Well done! A thick layer of fat and
hollow oily fur keep the polar bear
warm and help the bear float.

Can you pick out the four best adaptations for polar climates by clicking them below?
A short snout or nose.
Sorry, but this isn’t a useful
adaptation in a cold climate. A
short snout or nose won’t allow air
that is breathed in time to warm
up before it enters the lungs,
which leads to heat loss.

Claws and large, cup like feet.
Well done! Claws act like ice picks
and large cup-like feet act like
rubber to provide grip and friction
on ice and snow.

Sorry, ice builds up on eyelashes
in polar regions! Long eyelashes
are a more useful adaptation for
dusty or sandy environments as
they stop dust and sweat entering
the eye.

Well done! Small ears and a very
rounded body shape help to
prevent heat loss as they reduce
the surface area and lower the risk
of frostbite on the extremities.

A feature that helps a living thing to survive is called an “adaptation” e.g.
large eyes are more effective in darkness (they take in more light).
Q. Name three different
physical features (adaptations)
the wild Bactrian camel has
that help it to survive in the
desert. e.g. humps that store
fat supplies.

Q. What are its adaptations?
Next slide
The marine iguana's
adaptations are:
• A blunt nose for grazing algae
(seaweed) from rocky shores.
• Long claws and powerful grip
for clinging to rocks.
• A more streamlined shape for
cutting through water.
• A flatter wider tail for
swimming underwater.

Plants have adaptations too such as rolled, hairy or waxy leaves
to hold in water and deep roots to tap into water supplies:
This film clip shows the Coco-demer palm tree’s “seed”.
It is one of the largest, heaviest
(and one of the toughest) seeds in
the world.
Q. Why might these adaptations
have developed over many
generations of palm trees?

•
It is thought that the seeds
developed because they needed
to survive the long journeys at
sea, where saltwater would
normally ruin seeds that were
less sturdy and resistant.
In addition to this they have to
survive the drop from the top of
the palm tree (up to 34 metres)

Remember: A physical
feature that helps a
living thing to survive is
called an “adaptation”
e.g. camouflage to hide
from prey or predators
or deep roots to find
water.

Q. Name two adaptations that snow leopards have.
Next slide
The snow leopard’s adaptations
are:
• Camouflage helps to hide them
from prey.
• Thick fur helps them to keep
warm.
• A long tail for balance.
• Forward facing eyes (like most
predators) to pick out detail and
to judge distances accurately.
