List of 1-syllable Animals that contain O

1

Cow

Bos taurus

The world's most numerous large domesticated mammal — bred for milk, meat, leather, and labor across nearly every continent for over 10,000 years.

2

Dhole

Cuon alpinus

Asia's wild dog — a highly social, pack-hunting canid of South and Southeast Asian forests that kills prey far larger than itself through cooperative strategy; dholes can drive tigers and leopards from their kills, communicate with extraordinary calls including whistles and clucks, and their packs may number over 30 individuals.

3

Fox

Vulpes vulpes

The most widespread wild canid on Earth, an adaptable omnivore with a luxurious red coat, white-tipped tail, and a notorious reputation for cleverness.

4

Frog

Anura (order)

A diverse order of tailless amphibians — over 7,000 species worldwide, ranging from microscopic to football-sized, with skin that breathes, tongues that snap, and an outsized role in ecological monitoring.

5

Goat

Capra hircus

A small horned ruminant domesticated alongside sheep at the dawn of agriculture — kept globally for milk, meat, fiber, and as remarkable browsers in difficult terrain.

6

Horse

Equus ferus caballus

A large hoofed mammal domesticated 5,500 years ago on the Eurasian steppe — central to human history as transport, agriculture, warfare, and sport, with hundreds of breeds adapted to specific tasks.

7

Mole

Talpidae (family)

A small underground mammal with paddle-like front feet for digging — found across most of the northern hemisphere, dug-into-the-ground specialists with extraordinarily refined sense of touch and a near-permanent underground existence.

8

Moose

Alces alces

The largest living deer species — North American and Eurasian, browsing on aquatic plants and tree bark, capable of being unexpectedly aggressive and outweighing most cars they collide with.

9

Mouse

Mus musculus (house mouse)

One of the most successful mammals on Earth — house mice have followed humans worldwide, while wild mice species number in the dozens, serving as both pest, prey, and the most-used laboratory animal in modern biology.

10

Quoll

Dasyurus maculatus

A spotted carnivorous marsupial from Australia and New Guinea — a fierce predator relative to its size, critically threatened by foxes, cats, and cane toads, and one of Australia's most important native predators.

11

Sloth

Bradypus variegatus (brown-throated sloth)

A slow-moving, tree-hanging mammal native to Central and South American rainforests, so sluggish that algae grows on its fur — providing camouflage and a small ecosystem.

12

Stoat

Mustela erminea

A small, fierce mustelid — an elongated, chestnut-brown predator with a cream underside and a black-tipped tail; stoats are specialist rabbit hunters, able to pursue prey much larger than themselves, and can send entire rabbit warrens into paralysed panic; in northern Britain and at altitude, they turn pure white (ermine) in winter, retaining only the black tail-tip.

13

Wolf

Canis lupus

The largest wild canid, a deeply social pack-hunter with the broadest historical range of any wild mammal except humans, and ancestor to the domestic dog.
