Living in Cold Places

• Humans are not adapted to living in very cold
  places.
• Animals that live in the Arctic and the Antarctic
  are well-adapted to these conditions.

2

• Lots of these animals have a thick layer of fat
  (sometimes called blubber) under their skin.
• This insulates them and keeps them warm.

3

• Lots of Antarctic or Arctic animals have thick
  fur or feathers that traps air next to the body
  and keeps them warm.

4

• Many animals that live in Arctic/Antarctic
  conditions are white in color.
• This provides them with camouflage in snow and
  ice.

5

• Many cold-weather animals are large in size.
• This means that they have a small surface area
  compared to their volume.
• A large surface area means that they lose more
  heat.

6

• Animals that live in cold conditions often have
  small extremities such as ears.
• Smaller ears means less heat loss.
• Very often, closely related tropical species have
  much bigger ears to help lose heat.
