Dictionary of Turtle Names

The truth behind pet-shop names, the double life of 'zenigame,' and how to read a scientific name. Follow the names, and the turtles come into focus.

Pet-shop Names & Nicknames

ミドリガメ→ Pond Slider
The classic pet-shop name for hatchling red-eared sliders, whose shells are bright green only in childhood. The green fades with age — the name never did.
ゼニガメ→ Chinese Pond Turtle
"Coin turtle." In the Edo period it meant Japanese pond turtle hatchlings; in modern pet shops it almost always means baby Reeves's turtles. Same name, different turtle, depending on the century.
ゾウリガメ→ Chinese Pond Turtle
"Sandal turtle" — a folk name you will not find in any field guide, likening a flat oblong shell to a zōri sandal. It usually referred to grown Reeves's or Japanese pond turtles. Not an official name, which is why dictionaries stay silent about it.
イシガメ→ Japanese pond turtle
Short for Japanese pond turtle (Nihon ishigame) — the 'stone turtle,' named for its stony shell tones.

Japanese Turtle Names

クサガメ→ Chinese Pond Turtle
The 'stinky turtle,' named for the musky odor it can release when threatened. Surprisingly, the name was only formalized in a 1934 paper.
スッポン→ Chinese Softshell Turtle
The Japanese softshell. One beloved etymology says the name imitates the 'zubon!' splash it makes diving into water.
ウミガメ→ Green Sea Turtle
Umi-game simply means 'sea turtle' — but each species' full name hides its own story: the green turtle is named for its fat, the loggerhead (aka-umigame, 'red sea turtle') for its reddish shell.
ワニガメ→ Alligator Snapping Turtle
'Crocodile turtle' in Japanese; English goes further with 'alligator snapping turtle.' Both languages saw the same beast.
カミツキガメ→ Common Snapping Turtle
'Biting turtle' in Japanese. The Latin serpentina ('snake-like') describes its long striking neck instead — two languages, two features.
リクガメ→ Hermann's Tortoise
Riku-game means 'land turtle.' The 'Hermann' honors the 18th-century French naturalist Johann Hermann — species names are full of quietly immortalized people.

Turtle Names of the World

マタマタ→ Matamata
Thought to come from an Indigenous South American word often glossed as 'skin' — fitting for a turtle draped in flaps and fringes.
ガラパゴスゾウガメ→ Galápagos Giant Tortoise
The islands are named after the tortoise, not the other way around: galápago is Spanish for turtle. The Galápagos giant tortoise is, literally, the tortoise of the Turtle Islands.
アルダブラゾウガメ→ Aldabra Giant Tortoise
Carries the name of the Aldabra Atoll; the Latin gigantea means exactly what you hope it means.
オサガメ→ Leatherback Sea Turtle
The Japanese name likens the shell's ridges to an osa, a weaver's reed. The Latin means 'leathery skin-turtle.' Craft tool or texture — pick your metaphor.
スッポンモドキ→ Pig-nosed Turtle
Modoki means 'imitation' — a softshell look-alike in a family of its own. English named it for its snout instead: the pig-nosed turtle.

Reading Scientific Names

Testudines(カメ目)
From the Latin testudo (tortoise). Roman legionaries called their shield-roofed formation the testudo — even Rome saw the turtle as the perfect defense.
Chelonia / chelys
The Greek khelōnē (turtle) hides inside countless scientific names — Chelonia, Dermochelys, Macrochelys. Spot 'chel' in a Latin name, and there is a turtle nearby.
mydas / imbricata / elegans
Species epithets are one-word field notes: mydas ('wet'), imbricata ('shingled', for overlapping scutes), elegans ('elegant'). Learn to read them and every checklist becomes literature.
