# Give it a Latin name and it exists

> The field guide plate is the most efficient worldbuilding format ever invented. Label the anatomy, add a binomial in italics, and an invented creature stops being a drawing and becomes a specimen.

There's an invented animal on that shirt. It has six legs, wings that don't match, and a name in
italics underneath.

The name is what makes it real. Without it, it's a nice drawing of something imaginary. With it,
somebody classified it — which means somebody found it, which means it exists.

## Why does the label do so much?

Because taxonomy is a claim about the world, not about a picture.

A binomial in italics implies an entire apparatus: a collector, a specimen, a museum drawer, a
person who argued about which genus it belonged in. None of that has to be drawn. The two italic
words carry it.

Add labelled anatomy — *ovipositor*, *tarsal claw*, *stridulatory ridge* — and the implication
deepens. Somebody didn't just find it; somebody dissected it.

## What are the components?

Five, and they're borrowed wholesale from nineteenth-century natural history.

- **A precise specimen illustration**, usually in a rigid diagnostic pose.
- **Fine hatching** for shading rather than tone.
- **Leader lines** to labelled parts, set in small italics.
- **A binomial** beneath, in italics, sometimes with a describing author and date.
- **A single ink** on aged paper stock.

This is the same tradition
[goth print design descends from](/stories/goth-print-design) — Victorian plates — used
for wonder rather than for memento mori.

## How do I invent a convincing name?

Two Latin-ish words: a genus that sounds like a place or a shape, a species that sounds like a
property or a person.

*Silvaptera nocturna*. *Fossorix gravis*. *Umbracollis maritimus*. The trick is that neither word
should be a joke — the moment the name is funny, the whole apparatus collapses and it becomes a
cartoon.

Deadpan is doing structural work here, not tonal work. The creature can be absurd; the label
cannot be.

## Can I use a creature from a game or a series?

No, and this genre tempts it heavily because monster compendiums are exactly this format.

Named creatures from games, films and card sets are designed assets and heavily protected. What's
free is the format itself, which predates all of them by two centuries and belongs to scientific
publishing.

Inventing the animal is also the whole pleasure. A field guide to creatures that don't exist is a
form with genuine depth — you can make a second one, and a third, and they accumulate into
[a collection](/stories/build-a-collection-not-a-shirt).

## What should the creature be?

Something built from real animals that shouldn't combine.

The convincing ones borrow their anatomy honestly: a pangolin's plating, a mantis's forelimbs, a
deep-sea fish's jaw. Real structural logic is what makes an invented animal look *found* rather
than designed —
[the same rule kaiju design runs on](/stories/kaiju-monster-poster-style).

What doesn't work is a creature made of concepts. Anatomy that couldn't function reads as a
doodle, and the format's deadpan then has nothing to be deadpan about.

## Does this print well?

Yes, with one caution about scale.

Fine hatching is pure line, so it holds up — but only at size. A detailed plate at chest scale is
excellent; the same drawing shrunk to a pocket mark turns grey, because
[the hatch spacing falls below what the weave can hold](/stories/bold-shapes-survive-fabric).

So this is a design that wants to be printed large. One ink on a dark ground, filling the chest.

## How do I get one made?

Describe the creature at [JustOG](/) — which real animals its parts come from, and what you're
calling it. 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).

Anyone can draw a monster. The Latin is what makes somebody believe it was caught.
