Hemocyanin

Standard

You and I

have new blood,

The oxygen we need,

pulled from each breath,

is cradled

in a molecular nest,

and bound in iron:

scarlet Hemoglobin.

But our ancient ancestors,

and the still-living

relics of the copper age,

still hold to

their old ways.

It courses through their veins,

blue

like the patina

on a penny,

that’s seen

better days.

Red blood caught on,

but ours is not the only way.

Our cousins in the deep,

also well-travelled,

use azure Hemocyanin

it still works it’s magic,

just like ours

but matches their lifestyle,

working tirelessly

undaunted by cold,

darkness,

and depth.

Flesh and blood,

follow their own

rhyme and reason,

what falls out of fashion

can often still function,

in the right place,

at the right time

and in the right hands.
