why we all need sleep

Hello everybody last week my group leaned about sleep. 

I am learning to read and find the appropriate information I am searching for.

Here I have three facts I have learnt so far.

Did you know that animals all need sleep however they do sleep in different kind of ways . some Animals even sleep while their standing up.
There are different kinds of sleep as well like REM sleep.
and did you know that Dolphins can swim while they are asleep  

the first article i read was all about sleep the is illustrator is Jill Mcdougall I think the author wrote this because it tells people About sleep
