Adaptation For Survival.
All living things have adaptations which help them to survive in the condidtions where they live.
Adaptations for hot, dry enviroments include a large SA/V ratio,thin fur, little body fat and behaviour patterns that avoid the heat of the day.
Changing coat colour in the different seasons gives animals year round camouflage.
Animals which are adapted for cold enviroments are often large; with a small surface area: volume ( SA/V) ratio. They have thick insulating layers of fat and fur.
