# ostrich vs saltwater crocodile

**ostrich vs saltwater crocodile: saltwater crocodile leads on 2 of 3 measures**

Measured comparison — not a prediction

The largest and fastest bird, laying eggs that weigh about 1.4 kg each. The largest living reptile and the animal with the hardest bite ever measured. On the measurements below, saltwater crocodile 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

|  | ostrich | saltwater crocodile |
| --- | --- | --- |
| Mass | 63–156 kg | 76–1,300 kg |
| Length | — | 2.5–6.3 m |
| Height | 1.7–2.8 m | — |
| Top speed | 60–70 km/h | 29 km/h |
| Bite force | — | 3,700 psi |
| Lifespan | 30–50 yr | 65–100 yr |

## Where each one leads

- Mass: saltwater crocodile is 4.5× heavier.
- Top speed: ostrich is 2.4× faster.
- Lifespan: saltwater crocodile is 1.8× 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 ostrich bigger than a saltwater crocodile?

saltwater crocodile is heavier — 76–1,300 kg against 63–156 kg.

### Who would win, a ostrich or a saltwater crocodile?

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.
