# capybara vs sperm whale

**capybara vs sperm whale: sperm whale leads on 3 of 3 measures**

Measured comparison — not a prediction

The largest rodent alive, a semi-aquatic grazer of South American wetlands. The largest toothed predator, diving to 2,000 m for squid and producing the loudest sound of any animal. On the measurements below, sperm 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

|  | capybara | sperm whale |
| --- | --- | --- |
| Mass | 35–66 kg | 15–57 t |
| Length | 1–1.34 m | 11–20.5 m |
| Height | 0.5–0.62 m | — |
| Lifespan | 6–12 yr | 60–70 yr |

## Where each one leads

- Mass: sperm whale is 800× heavier.
- Length: sperm whale is 15× longer.
- Lifespan: sperm whale is 6.7× 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 capybara bigger than a sperm whale?

sperm whale is heavier — 15–57 t against 35–66 kg.

### Who would win, a capybara or a sperm whale?

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.
