Adaptations.

"Adapt or perish, now as ever, is nature's inexorable imperative." - H. G. Wells

Animals, every single one, are all the way they are due to evolution. Not just evolution though - adaptations too. Every animal will have something that helps it thrive in its natural surrounding.

Look at the polar bear, its white coat helps it blend it with its surroundings, to hide from its prey - so it can sneak up, unnoticed, and attack. Due to this adaptation it get more food, and therefore can live longer. It also has a thick layer of fat - it lives in the arctic right?

Its cold there.

Its thick layer of fat helps it stay warm, as well as thick fur. They're well suited for a chilly winter! Ever noticed there large paws? This helps them walk along the snow - its spreads their weight out so they can walk better. They're well suited, arctic machines if anything.

From hot to cold, the camel. What are its adaptations? Well to start off, a more 'subtle' adaptation is its long eyelashes, these help to keep sand out of its eyes - its windy there y'know! They also can for weeks without water! This helps them survive in the desert conditions. They also can go for months without food, this helps on long journeys.A camel's body temperature changes throughout the day from approximately 34°C to 42°C. This helps the camel stop sweating, so it can keep more water. They also have wide feet too! This helps them walk on the sand without sinking in! Their ears are coated with hair, inside and out to help keep sand and dust out, they also have thick lips - so they can eat all the 'prickly' plants and finally they can blend in with the surroundings due to the colour of their bodies!

Many animals are suited perfectly to their environments, even us. They could not survive with there adaptations, they thrive because of them. Next post will be about human adaptations and what we use them for! Sorry for the short post.

Thanks for reading, Ben.
