# bull shark vs grizzly bear

**bull shark vs grizzly bear: grizzly bear leads on 2 of 3 measures**

Measured comparison — not a prediction

The only large shark that tolerates fresh water, found far up rivers including the Mississippi and Amazon. The inland North American brown bear, smaller than coastal populations because it eats less salmon. On the measurements below, grizzly 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

|  | bull shark | grizzly bear |
| --- | --- | --- |
| Mass | 90–316 kg | 130–360 kg |
| Length | 2.1–3.5 m | 1.7–2.4 m |
| Height | — | 0.9–1.1 m |
| Top speed | — | 56 km/h |
| Bite force | — | 975 psi |
| Lifespan | 12–32 yr | 20–35 yr |

## Where each one leads

- Mass: grizzly bear is 2.1× heavier.
- Length: bull shark is 1.2× longer.
- Lifespan: grizzly bear is 1.6× 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.

## Common questions

### Is a bull shark bigger than a grizzly bear?

grizzly bear is heavier — 130–360 kg against 90–316 kg.

### Who would win, a bull shark or a grizzly bear?

That is not something measurements can settle. The comparison above shows which animal leads on each measure, but an actual encounter depends on circumstance, motivation, health and terrain — and most pairs like this never meet in the wild.
