Science behind animal shakes PIGS do it. Mice do it. Dogs also do it. Kangaroos? Not so much. Why do animals shake? The .short answer is,because they’re wet. But there’s actually more to it than that - a lot more.

Firstly, scientists find out that mammals (哺动物)save a large amount of energy by doing their cute little shakes. If they do not shake, animals, especially furry (多毛的)mammals would have to use up to 20 percent of their daily energy simply avoiding being wet.

Those that don’t, like kangaroos who shake only part of their body, usually live in desert climates (;少漠气候)where it is very hard for them to get wet.

Secondly, not all animals shake at the same rate (速率).

Smaller animals seem to shake more quickly, 30 shakes per second for a mouse, while bears, tigers and big dogs average (平均)only about five.

In an interesting finding, one scientist and his team have shown that these animals do the job as efficiently (有效地)as possible. In each case, the animals shake off about 70 percent of water in a few seconds. This should all be impressive to humans. It takes us not seconds but minutes to dry our hair just over three percent on average.

Fact

Mammals, especially furry mammals shake.

Reason

It is believed that thev shake 1 of being wet.
