In chapters long before, the nautiloid
Had built his coiled shell of chambered pride
And ruled the ancient seas where all deployed
Their forces in the ocean's deep and wide.
Two paths diverged from that ancestral coil:
One kept the shell and wore it like a crown,
The other chose to shed that calcite toil—
And each would win a glory of renown.
Ammonos kept the outer shell and grew
Its whorls in patterns ever more ornate:
The suture lines that held each chamber true
Grew folded, fractal, beautifully intricate—
From simple curves to gothic tracery
Of saddles, lobes, and ridges intertwined,
As if the shell itself were artistry
That nature carved but never quite defined
In any final form—for Ammonos
Wore every variation shell could take:
Some broad as cartwheels, flat as river stones,
Some tall and narrow like a coiled snake,
Some spined with thorns, some smooth as polished bone,
Some small as coins and some as large as men—
No cephalopod has ever matched the throne
Of shell diversity he held back then.
Through every ocean, warm and cold alike,
From shallow reef to deep abyssal floor,
His children filled each niche and every strike
Of evolutionary fortune opened more—
So many forms that those who study stone
Cannot untangle who begat whom next:
The tree of Ammonos remains unknown
In all its branching—tangled, rich, and vexed.
Yet all of them were taken in the end:
When the great dying struck the Mesozoic's close,
Not one of Ammonos' line would bend
Or find a refuge from those final throes.
The nautiloid survived—the ancient form—
But every ammonite was swept away,
Their shells now spiral fossils from the storm
Of extinction's unforgiving day.
But from that shell-coiled lineage one would spring
Who chose a different path for all his kind:
Coleios turned the shell to inner thing
And let the body flow unshelled, resigned
To no fixed form—for if the shell is hid
Then no shell-crushing jaw that ever grew
Could crack it—every jaw of every squid-
Killer aimed at shells that it once knew
Was visible, projecting, outer-worn:
But Coleios put his shell inside
And left his predators forever torn
Between a shape they knew and what they'd find.
No outer armor—only speed instead,
And jet-propulsion, water-forced and fast:
He squeezed his muscled mantle, shot ahead
Through open water, leaving predators last
Who'd aimed at where he'd been a breath before—
The rocket of the ancient ocean's hall,
Who turned the very water to a roar
Of thrust and found escape beyond them all.
Four children had great Coleios in his time:
First Belemno, whose internal shell remained
As solid cylinder of calcite prime—
A bullet in his flesh that strength maintained.
His children filled the Mesozoic seas
With numbers past what any eye could count,
Like bullets scattered on the ocean's leas
Their rostral shells in limestone strata mount
In layers feet-deep—witness to the age
When Belemno's children ruled the waters cold
And hungry—fossil-filled on every page
Of limestone cliff from young to very old.
Then Sepos turned the shell to softer page:
A flat and porous cuttlebone that bold
And buoyant kept him in the middle column,
Adjusting depth by gas sealed in the bone—
A solemn engineer, precise and solemn,
Who mastered buoyancy entirely alone.
His skin could ripple with a thousand shades
In milliseconds—chromatophores bright
That opened and contracted in cascades
Of color-signal visible in light:
The cuttlefish communicates in waves
Of color, pattern, pulse along his side—
A living language that the ocean saves
From silence, given freely without pride
Or need for listener—the signal spreads
Across his entire skin at once in flow
Of rippled meaning, signaling the threads
Of mood and mate-choice for all around to know.
Young Teuthis shed the inner shell at last
And kept instead a thin and translucent quill
Of chitin—ghost of shell from ancient past—
That gave his long and streamlined body still
The structure for his mantle muscles' pull
While letting him grow longer, faster, sleek:
Ten arms, eight short and two extended full
For catching prey that other hunters seek.
The giant squid—great Architeuthis' kind—
Would grow to arms of forty feet in reach
And haunt the deep where no light is defined:
The sea monster of every sailor's speech,
Whose battles with the sperm whale in the dark
Of ocean's midnight left great scars of round
Upon the whale's great face—the sucker's mark
Of combat in the deep where light's not found.
But Octopos dissolved the shell entire—
Not quill, not cuttlebone, not rostra stayed—
And in that loss gained something to aspire:
The boneless body could reshape and wade
Through any gap, beneath any rock or door,
Could pour himself through openings as small
As any of his beaks—no solid core
To limit where his eight-armed self could crawl.
And in that fluid bonelessness he gained
The largest brain relative to size
Of any invertebrate—unrestrained
Intelligence that chooses to disguise
Itself in eight arms and two jewel-like eyes,
Who opens jars and learns from watching peers,
Whose sleep resembles something that implies
A dreaming—complex mind that always steers
Around the simple answer toward the best:
He changes color, texture, profile, veers
From background into invisibility's test—
The master of disguise that disappears
By wearing what surrounds him as his skin,
By being rock when still and current when
He moves—by turning the outside within
And wearing what he is not, yet again
And yet again until the hunter sees
Nothing where Octopos had been a breath
Before—and so he crosses the high seas
Of danger daily, never meeting death.
The ink itself—defense of all this line—
Became their signature upon the tide:
A cloud of darkness drawn along the brine
Where predators would see the prey inside
Still visible and close—then nothing there
But purple-black uncertainty instead:
The lords of ink escaped through their own care
To leave behind a decoy of the dead
Dark water in the shape of what they were.
So honor Ammonos and his spiral crown,
And Coleios who made the visible a blur—
Two paths from one coiled ancestor laid down:
One kept the shell and filled the seas with form
In countless variations, broad and tall,
Then perished wholly in extinction's storm;
The other shed the shell and outlived all.
From Belemno's bullet to Octopos' mind,
From Sepos' color-speech to Teuthis' reach,
The coleoids proved that those who leave behind
The visible protection find a speech
More powerful than armor—the disguise,
The speed, the ink, the shapeshifting of form,
The distributed mind in eight-armed guise—
These are better armor than the norm.
