Her name was Opa, she was a sea bug
With shapely lobes along her sides and a sexy set of eyes
A long proboscis, a backwards mouth
She really hoped to be a star... Even though she looked bizarre
She swam not far from the shore along the ocean floor
She was young and had five eyes
Who could ask for more?

Oh oh Opa, Opabinia
The cutest worm in the deep sea-uh
Oh oh Opa, Opabinia
Your segmented body made you such a hottie
Oh oh Opa... Her life was good...

His name was Darwin, he had a theory
Only the fittest will survive, and the rest will cease to thrive
He looked at Opa, made a prediction:
You're a very pretty worm, but your luck's about to turn
The meteor hit top side, the shock was felt world-wide
There was steam and a tidal wave
Where could Opa hide?!

Oh oh Opa, Opabinia
You've got your own page on Wikipedia
Oh oh Opa, Opabinia
Your form and function just weren't in conjunction
Oh oh Opa... She went extinct...

Her name was Opa, she was a seabug
Half a billion years ago, in the Cambrian doncha know
Now she's a fossil, one of just twenty
Her mineralized remains, were discovered in the plains
We're very sorry, lord, our climate we've ignored
Our planet's ♥♥♥♥♥♥ and we might just get
A Darwin Award!

Just like Opa, Opabinia
The fittest survive, that's the idea
Oh oh Opa, Opabinia
The temperature's rising, and it's not too surprising
Oh oh Opa... We'll see you soon...
We'll see you soon...
