Arctic Fox

Behavioural

Sheds winter coat for a thinner greyish-brown coat during summer

Uses ice floes to travel in search of food in the winter

Hide food in its den or under rocks during summer - storing food for use in winter

Curl up in the snow and cover its nose and face with its bushy tail - keep warm

Structural

Oily fur sheds water and helps to keep the fox dry

Camouflage - In winter its thick, bushy coat turns white.

Has thick coat - allow it to survive in freezing cold temperatures

Has thick hair on the pads of their feet - protects their feet from freezing and helps them to walk on the ice.

Adaptations of Animals in Polar regions

thats really cool

Whales

Nostrils open on top of the head

raises to the surface to take in oxygen

Thick blubber (fats)

source of water

food store during starvation

increases buoyancy

decreases heat loss

Lack of hair hep

decreases friction as it moves in water

respiration

-it breathes thorugh its nostril

Flippers

-limbs are adapted as flippers

-skin on the soles of the walrus's flippers is thick and rough to provide traction on land and ice

-in water, it holds it's short and square foreflippers for steering in the water

-on land,it position its foreflippers at right angles to the bofy for walking

air sac

air sac under its throat which acts like a floatation bubble and allows it to bob vertically in the water and sleep

long tusks

long tusks are used ofr fighting, dominance and display.

they are also used to form and maintain holes in the ice and help it in the climbing out of water onto ice

skin

-has a blubber layer up to 15cm thick to keep it warm

Main topic

Penguins

"Tobaganning" movement

This is when the penguin slides on its belly to conserve energy when moving quickly.

Underwater vision

Eyes are adapted for underwater vision as this is the primary means of locating prey and avoiding predators.

Countershaded skin

The white belly provides camouflage (as it is similar to the reflective water surface). The black back also provides camouflage (from aerial view).

Vestigial wings

Useless in flight but act as excellent flippers for competent movement in the waters.

Closely packed modified feathers

The smooth, thick-layered plummage allows an air layer to be preserved thus ensuring buoyancy as well as insulation in a cold environment.

Black Brow albatross

salt glands(on nose)

to excrete excessive salts, thus maintain water potential in blood

produce stomach oils

use against predators

as rich food source for long flights

Long-winged span

energy-saving, able to soar in the wind for long distances

Polar bears

Postures

Eating Habits

Humans

Walrus

Seals

Physical Appearance

Subtopic

Weight: 350–680 kg

White in color
