Platypus

Sleeping geology
On the isolated shore
For millions of years

Experimental continent
On purpose or accident?

Mysterious evolving
Problem solving

A vaudeville? A nation including one superior creation
A vertebra? Inverted...quite unheard of...

Orphan in a family
And a sole survivor
He's a living fossil

Reptillian? Mammalian
He's a bird-beaked, beaver-butt Australian

Amphibious? Paradox wearing plaid socks
Furry beetle? A bugbear, and a palezoologist's nightmare
Symmetrical physique of disbelief

The platypus has the brain of a dolphin
and can be seen driving a forklift in his habitat of kelp
He is the larva of the flatworm
and has the ability to regenerate after injury

No relation to the flounder.

Someone shipped him to the blokes
Who said he was a hoax
So they cut him to pieces, wrote a thesis

A cranium of deceit, he's prone to lie and cheat
It's no wonder -- a blunder from down under

Duckbill, watermole, duckmole!

Barnacle
