Shhh Koala Poem by Ima Ryma

Koalas have a quite deep pitch,
So very low, given the size.
So scientists just got the itch
To dig in deeper for the whys.
Some koalas did 'volunteer'
Their voice boxes for a look see.
Extra vocal cords did appear.
Outside of the larnyx these be
Discovery that did excite.
Koala sound solved - a big deal.
The scientists expressed delight,
In long and varied high pitched squeal.

Koalas - few are making sound
When scientists may be around.
