Koala Life Cycle

I read about koalas.  An important vocabulary word in my book is marsupial.  It means mammals with pouches.  Koalas have pouches like kangaroos.  They use less energy when they sleep than they do when they are awake.  A male koala makes a lot of noise so that females will notice him.  He bellows loudly from treetops so females that are nearly will notice and find out what all the racket is.  It can be heard up to half a mile away!  Koalas go from embryo inside the pouch to six-month joey to adult.
