# Nile crocodile vs saltwater crocodile

**Nile crocodile vs saltwater crocodile: saltwater crocodile leads on 3 of 3 measures**

Measured comparison — not a prediction

Africa's largest crocodilian and, by most counts, the animal responsible for the most human deaths on the continent. 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

|  | Nile crocodile | saltwater crocodile |
| --- | --- | --- |
| Mass | 225–750 kg | 76–1,300 kg |
| Length | 2.4–6 m | 2.5–6.3 m |
| Top speed | — | 29 km/h |
| Bite force | — | 3,700 psi |
| Lifespan | 45–80 yr | 65–100 yr |

## Where each one leads

- Mass: saltwater crocodile is 1.4× heavier.
- Length: saltwater crocodile is 1.1× longer.
- Lifespan: saltwater crocodile is 1.4× 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 Nile crocodile bigger than a saltwater crocodile?

saltwater crocodile is heavier — 76–1,300 kg against 225–750 kg.

### Who would win, a Nile crocodile 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.
