grizzly bear vs lion

The inland North American brown bear, smaller than coastal populations because it eats less salmon. The second-largest living cat and the only one that lives in permanent social groups. The measurements below split evenly, which is rarer than it sounds.

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.
