# American bison vs orca

**American bison vs orca: orca leads on 3 of 5 measures**

Measured comparison — not a prediction

The heaviest land animal in the Americas; commonly called a buffalo, though true buffalo live in Africa and Asia. The largest dolphin and an apex predator everywhere it lives; distinct populations specialise on different prey. On the measurements below, orca 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

|  | American bison | orca |
| --- | --- | --- |
| Mass | 320–1,270 kg | 1,300–10,000 kg |
| Length | 2.1–3.5 m | 5–9.8 m |
| Height | 1.5–2 m | 0.9–1.8 m |
| Top speed | 56 km/h | 56 km/h |
| Lifespan | 15–25 yr | 30–90 yr |

## Where each one leads

- Mass: orca is 5.3× heavier.
- Length: orca is 2.3× longer.
- Height: near enough identical.
- Top speed: near enough identical.
- Lifespan: orca is 2.5× 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 American bison bigger than a orca?

orca is heavier — 1,300–10,000 kg against 320–1,270 kg.

### Who would win, a American bison or a orca?

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.
