Sea sowers

I cannot help but stop and look at bleached seashells.

Never forget the artificial and faded seashells.

How happy are antarctic echinoderms!

Never forget the polar and south-polar echinoderms.

When I think of flatworms, I see a tiny capacitance.

Never forget the wacky and fool flatworms.

I cannot help but stop and look at the cunning gastropod.

Down, down, down into the darkness of the gastropod,

Gently it goes - the artful, the tricksy, the cute.

Conchs, however hard they try,

Will always be giant.

Never forget the big and elephantine conchs.

Limpets, however hard they try,

Will always be antarctic.

Are you upset by how south-polar they are?

Does it tear you apart to see the limpets so polar?
