# A creature drawn like a specimen, not a monster

> Deep-sea specimen illustration uses one light source, a black ground and stipple to describe rather than alarm, and the depth figure printed beneath does more work than the creature.

An engraved illustration of a creature that doesn't exist, lit from one side against total black.
One pale lure. A mouth set with fine, close teeth, built up in stipple and fine hatching the way an
old specimen plate would be. Beneath it, small: `2,340 M`.

That number is the part that's actually true.

## Why does a specimen drawing scare more than a horror illustration would?

Because a specimen drawing isn't trying to frighten anyone — it's trying to be accurate, and
accuracy about something like this is worse than exaggeration.

Scientific illustration has its own conventions: a single light source, so the reader can tell what
the surface is doing; a black or neutral ground, so nothing distracts from the specimen; stipple and
line work built up slowly rather than shaded broadly, because it has to survive being printed small
in a journal. None of that vocabulary is designed to unsettle. It's designed to describe, precisely,
something that was actually observed, and borrowing that whole toolkit for a creature that wasn't
observed keeps every ounce of its authority intact.

## What is the depth figure actually doing?

`2,340 M` is a real kind of measurement, describing a real kind of place, even attached to a
creature that isn't real.

Total darkness starts a few hundred metres down. At 2,340 metres, no sunlight has ever reached that
water, at any time — it isn't gloom, it's a place with no light in it at all. Printing a specific
figure beneath the drawing borrows that fact and hands it to the creature, which does more than any
additional monster detail could: [a number does exactly this kind of work when it's precise and left
alone](/stories/numbers-as-a-design).

## What makes a good invented specimen?

Restraint on the anatomy, and total commitment to the light.

One lure. One set of teeth. Nothing added for incident — no second creature in the background, no
visible wound, no scale reference beyond the depth figure itself. The single light source is the
harder discipline, and it matters more on a chest print than it would in a book, since
[a chest print has one focal area to organise the whole drawing around](/stories/composition-for-a-chest-print):
everything on the far side of the creature from the light needs to actually disappear into the black
ground rather than being visible-but-dark, or the drawing stops reading as lit and starts reading as
merely dark.

## What about the rights on real species illustration?

Real specimen plates and species descriptions have illustrators and institutions behind them, so
the honest move is to invent the creature rather than copy one.

Natural history illustration is credited work — a named illustrator, often commissioned by a museum
or a journal, drew that exact plate of that exact specimen, and it sits in an archive that holds
rights to it. The scientific illustration *convention* — single light, black ground, stipple — has
no owner and never did; illustrators have used it identically for two centuries. An invented
creature drawn in that convention gets the authority without borrowing anyone's actual plate.

## Does the format work for a creature that isn't from the deep sea?

Anywhere the convention's darkness is literal rather than decorative.

A cave system, an unlit attic, the inside of something sealed — anywhere a single light source and a
genuinely black ground would be the honest way to draw the place, not just an atmospheric choice.
The depth figure generalises the same way: a real number attached to a real kind of absence, whether
that's metres of water or years since somewhere was last opened.

## Isn't an invented species less unsettling than a real deep-sea fish would be?

No, because a real one can be looked up, and looking it up ends the design's job.

A real anglerfish has a name, a size, a distribution map and several documentaries about it. The
mystery has an answer, and the answer is a fish. An invented creature has no page to find, which
means the depth figure and the drawing itself are the entire available information, indefinitely.
That's not a lesser version of the real thing; it's the format doing something a real specimen plate
can't.

## Does it print well?

Yes, with one adjustment: the stipple needs to open up.

Fine stipple built for an illustration plate sits well below what a shirt's weave can resolve, and
it will fill in to grey rather than hold as texture, so the dots want to be fewer and larger than
the source drawing, with the darkest areas trusting flat black rather than dense stippling to get
there. [A short palette does the rest of the work](/stories/limited-palette-prints-better):
near-black or deep charcoal for the base, a single pale ink for the creature and the depth figure,
and nothing else.

## How do I get one made?

Describe the creature at [JustOG](/) — the light, the one distinguishing feature, and the depth.
Pick a direction, drag the crop frame, see it composited on the real garment, and it's made to order
and shipped.

Designs other people have published are in the [shop](/shop).

A single lure, lit from the left, and a number that's true.
