Sonnet Dare: In Which I Cotton To A Coconut-Carting Cephalopod

It's veiny, vaguely pink and near some nuts --
But get thy mind from yonder gutter, please!
I'm speaking of a freaky octopus
Who lives exposed in sandy-bottomed seas,
The Amphioctus marginatus would
Be vulnerable there were not for its
Ingenious use of coconut shells, good
As snail or nautilus ones, when they fits
The octopus's body. When it must
Go roaming, Marinatus sometimes goes
On two tip-tentacles; the others just
Wrapped tightly 'round his head; therefore what shows
Looks like a walking coconut. So smart!
He shows Cthulhu's lineage in part.
