Survived a week, I have; a week I have

survived. You thought me weak, you did; you smiled

that smile, that grin where you believe me flanked

and in that lucid moment, I profiled

your mask, at last, I recognised that smirk,

I wrote of it in verse, blank verse, as blank

as evil eye membraned* for bloody work -

dilating, celebrating as I shrank -

oh, you have duplex retinas, you are

duplicitous, Cronus! You steer the dark

and Dark steers you to wander murk, mirrored*

for ugly work as suits a brutal shark.

...

Finned avatar in search of easy prey,

my vertebrae's no longer your mainstay.

*Some sharks have a nictating membrane, or a clear membrane that covers and protects the eye when a shark bites its prey

*shark eyes are equipped with a layer of mirrored crystals located behind the retina.
