# sperm whale vs three-toed sloth

**sperm whale vs three-toed sloth: sperm whale leads on 3 of 3 measures**

Measured comparison — not a prediction

The largest toothed predator, diving to 2,000 m for squid and producing the loudest sound of any animal. One of the slowest mammals, moving about 0.24 km/h and descending from its tree only to defecate. 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

|  | sperm whale | three-toed sloth |
| --- | --- | --- |
| Mass | 15–57 t | 2.2–6.3 kg |
| Length | 11–20.5 m | 0.42–0.8 m |
| Top speed | — | 0.24 km/h |
| Lifespan | 60–70 yr | 20–40 yr |

## Where each one leads

- Mass: sperm whale is 10000× heavier.
- Length: sperm whale is 27× longer.
- Lifespan: sperm whale is 2.0× 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 sperm whale bigger than a three-toed sloth?

sperm whale is heavier — 15–57 t against 2.2–6.3 kg.

### Who would win, a sperm whale or a three-toed sloth?

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.
