# blue whale vs saltwater crocodile

**blue whale vs saltwater crocodile: blue whale leads on 4 of 4 measures**

Measured comparison — not a prediction

The largest animal known to have lived, heavier than any dinosaur and audible to other whales hundreds of kilometres away. The largest living reptile and the animal with the hardest bite ever measured. On the measurements below, blue whale 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

|  | blue whale | saltwater crocodile |
| --- | --- | --- |
| Mass | 50–190 t | 76–1,300 kg |
| Length | 21–33.6 m | 2.5–6.3 m |
| Top speed | 20–37 km/h | 29 km/h |
| Bite force | — | 3,700 psi |
| Lifespan | 70–90 yr | 65–100 yr |

## Where each one leads

- Mass: blue whale is 260× heavier.
- Length: blue whale is 5.6× longer.
- Top speed: blue whale is 1.3× faster.
- Lifespan: blue whale is 1.1× 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 blue whale bigger than a saltwater crocodile?

blue whale is heavier — 50–190 t against 76–1,300 kg.

### Who would win, a blue whale 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.
