polar bear vs snow leopard

The largest living land carnivore, classified as a marine mammal because it hunts from sea ice. A high-altitude cat of Central Asia with a tail almost as long as its body, used for balance. On the measurements below, polar bear leads on more of them — but they do not all point the same way, and the ones that disagree are the interesting part.

The measurements

Where each one leads

• Mass: polar bear is 11× heavier.
• Length: polar bear is 2.2× longer.
• Height: polar bear is 2.2× taller.
• Lifespan: polar bear is 2.1× a longer life.

What this does and does not tell you

These are measured averages with real ranges behind them, and every figure links to its own page. What they cannot do is settle an encounter. Outcomes between animals turn on circumstance — who initiates, whether either is hungry, defending young, injured or cornered, and what the terrain favours. Size and bite force are not decisive on their own, and most of these pairs never meet in the wild in any case, because their ranges do not overlap.

Every figure here is an average with a substantial spread. Individual animals vary enormously — a large individual of the smaller species routinely exceeds a small individual of the larger one.
