High on a cliff in the mountains of Asia, a grey shape rests on a ledge. Its spotted coat matches the rock so well that people can walk past without noticing it. Only when it flicks its long, thick tail does it give itself away.
Snow leopards are adapted to cold, steep, high mountains. Their key adaptations are thick fur, wide furry paws that act like snowshoes, a large nasal cavity that warms icy air, and a tail up to 1 m (3.3 ft) long for balance, says San Diego Zoo Wildlife Alliance. They are so hard to find that scientists knew very little about them until the 1970s.
Key takeaways
- 3 key adaptations: a long, thick tail for balance and warmth; big, fur-soled paws for snow and rock; a large nasal cavity that warms cold air.
- Home: mountains of Central and South Asia, usually between 3,000 and 4,500 m (9,800 to 14,800 ft).
- History: named by science in 1775, first studied closely in the wild in the 1970s, and first radio-collared later by researchers in Mongolia.
- Status: Vulnerable on the IUCN Red List since 2017, a change some scientists still dispute.
What are the main adaptations of a snow leopard?
A snow leopard’s body is built for cold, thin air and steep rock. Its fur is thick, its paws are wide and furry, its nose warms the air it breathes, and its strong chest and short front legs help it balance on cliffs. Its long tail works as a balancing pole and a scarf.
| Type | Adaptation | What it does | Key number |
|---|---|---|---|
| Structural | Long, thick tail | Balance on slopes; wrapped around the body when resting | 80–100 cm (31–39 in) |
| Structural | Thick fur | Keeps in heat | Up to 12 cm (4.7 in) on the belly in winter |
| Structural | Big, furry paws | Spread weight on snow; cushion and grip | Footpads about 9–10 cm long |
| Structural | Short front legs, strong chest | Balance when climbing | – |
| Physiological | Large nasal cavity | Warms cold air before it reaches the lungs | Larger than in related cats |
| Behavioural | Active mostly at dawn and dusk | Hunts when prey is moving and light is low | – |
| Behavioural | Huge home ranges | Finds enough prey in a barren land | Up to 1,000 km² |

How does a snow leopard stay warm?
With fur, a warming nose and its tail. Its winter fur grows up to 12 cm (4.7 in) thick on the belly, compared with about 2.5 cm (1 in) on the sides in summer, says Animal Diversity Web. Its large nasal cavity warms icy air before it reaches the lungs, and it wraps its thick tail around itself when resting.
Cats in warm climates do not have such dense fur, notes San Diego Zoo. The fur also covers the soles of the feet, which protects them from the cold ground.
Why does a snow leopard have such a long tail?
For balance and warmth. The tail is 80 to 100 cm (31 to 39 in) long and sometimes as long as the cat’s body, says San Diego Zoo. When the cat leaps or turns on a steep slope, the tail swings to keep it steady. At rest, the cat curls it over its face and paws like a scarf.
Picture it: a tail as long as a metre stick
A snow leopard’s body is about 1 to 1.3 m (3.3 to 4.3 ft) long, and its tail adds another 0.8 to 1 m, about the length of a metre stick or yardstick. Yet the whole cat usually weighs only 35 to 45 kg (77 to 99 lb), says Animal Diversity Web. That is roughly half the weight of an average American woman, about 78 kg (172 lb) according to the CDC.
How do snow leopards move on cliffs and snow?
With wide paws, strong legs and big jumps. Their footpads are about 9 to 10 cm (3.5 to 3.9 in) long, says Animal Diversity Web, which spreads their weight like a snowshoe. Short, muscular front legs and a strong chest help them balance on ledges, and they can leap up to six times their body length, says San Diego Zoo.
They live mostly on cliffs and rocky slopes below the permanent snow line. Animal Diversity Web gives their range as 900 to 5,500 m (about 3,000 to 18,000 ft) above sea level, though they usually stay between 3,000 and 4,500 m.
What do snow leopards hunt?
Mainly wild mountain sheep and goats. Blue sheep (bharal) and ibex are their main prey, and they can kill animals two to three times their own weight, says San Diego Zoo. Radio-tracking shows they bring down large prey every 10 to 15 days. Read more in what snow leopards eat.
When large prey is scarce, they also eat smaller animals such as marmots, hares and pikas, notes Animal Diversity Web.
Can snow leopards roar?
No. Snow leopards hiss, growl, moan and yowl, and they make a friendly puffing sound called a chuff, says San Diego Zoo, but they do not roar. That is unusual, because their closest relatives in the big cat genus Panthera, including the tiger, can.
How did scientists first learn about the snow leopard?
Slowly. Western science named it in 1775, based on an earlier description by the French naturalist Buffon. But for nearly two centuries almost nobody studied a living one in the wild. That changed in the 1970s with George Schaller’s surveys in the Himalayas, followed by the first radio-collar studies in Mongolia.
1761 to 1775: a name from a description
The German naturalist Johann Schreber gave the snow leopard its scientific name in 1775, according to the IUCN Cat Specialist Group’s 2017 cat taxonomy. He based it on a specimen described by Buffon in 1761. The exact place that animal came from is unknown. The name uncia comes from an old French word first used for the European lynx, says the Snow Leopard Trust, which is why the cat is still sometimes called the “ounce”.
1970s: the first close look in the wild
The American biologist George Schaller surveyed snow leopards and their prey across the Himalayas in the 1970s, says the Wildlife Conservation Society. In northern Pakistan he watched a snow leopard about 45 m (150 ft) away, which he described in his book Stones of Silence. His work also inspired Peter Matthiessen’s book The Snow Leopard, which made the cat famous worldwide, and helped lead to Pakistan’s Khunjerab National Park.
Later: collars, cameras and DNA
Schaller supported Tom McCarthy’s PhD research in Mongolia, which included the “first-ever radio collar research” on wild snow leopards, according to WCS. GPS collars came later, and San Diego Zoo notes that only recently has GPS tracking led researchers to a den with cubs. Genetic studies changed the family tree too. The Cat Specialist Group says DNA shows the snow leopard is the sister species of the tiger, so it is now placed in Panthera, not in its own genus Uncia.
Why is the snow leopard called the “ghost of the mountains”?
Because it is so rarely seen. Its grey, spotted coat blends with rock and snow, it lives alone in remote, steep places, and it is most active at dawn and dusk. San Diego Zoo calls snow leopards almost impossible to locate and study in their native habitat, which is why so much of their story was unknown for so long.
How many snow leopards are left?
Nobody knows exactly. The Snow Leopard Trust gives an estimate of 3,920 to 6,390 in the wild, while WCS gives 4,000 to 10,000. Their range covers more than 2 million km² of rugged mountains, so counts are hard. The main threats are poaching, loss of wild prey and damage to their habitat, says WCS.
In 2017 the IUCN Red List moved the snow leopard from Endangered to Vulnerable, after 45 years as Endangered. Not everyone agreed. In 2018, Charudutt Mishra and Som Ale argued in the journal Science that the assessment assumed snow leopards could breed younger than the evidence shows, which would inflate the count of adults, according to the Snow Leopard Trust.
Why do snow leopards matter to the mountains?
Snow leopards are the top predator of the high mountains. By hunting blue sheep, ibex and other grazers, they help keep those herds from overeating fragile mountain plants. Protecting snow leopards also protects the meadows, rivers and glaciers that many people downstream rely on, and the herders who share the land.
Myths about snow leopards
Myth: Snow leopards live in deep snow all year.
Fact: They mostly live on cliffs and rocky slopes below the permanent snow line, says San Diego Zoo, often in dry, barren mountains. Why people believe it: the name, and the famous winter photos.
Myth: Snow leopards are just leopards with pale fur.
Fact: They are a separate species, and DNA shows their closest relative is the tiger, not the leopard.
Myth: Snow leopards roar like lions.
Fact: They cannot roar. They chuff, growl, hiss and yowl.

Frequently asked questions
How do snow leopards survive the cold?
They have thick fur, up to 12 cm deep on the belly in winter, fur on the soles of their feet, and a large nasal cavity that warms cold air before it reaches the lungs. When resting, they wrap their long, thick tail around their body and face like a scarf.
How far can a snow leopard jump?
San Diego Zoo Wildlife Alliance says snow leopards can jump and pounce as far as six times their body length. Their powerful legs and long tail, which acts as a counterbalance, let them leap across gaps and pounce on prey on steep slopes.
When was the snow leopard discovered?
Local mountain peoples have always known it. Western science named it in 1775, when Johann Schreber described it from a specimen recorded by Buffon in 1761. Detailed study of wild snow leopards only began in the 1970s, with George Schaller’s surveys in the Himalayas.
How long do snow leopards live?
In zoos, snow leopards have lived to 21 years, says Animal Diversity Web. Nobody knows their typical lifespan in the wild, because they are so hard to follow for long periods in their steep, remote habitat.
