# bottlenose dolphin vs three-toed sloth

**bottlenose dolphin vs three-toed sloth: bottlenose dolphin leads on 4 of 4 measures**

Measured comparison — not a prediction

The dolphin most people picture, and the one most often kept in aquaria. One of the slowest mammals, moving about 0.24 km/h and descending from its tree only to defecate. On the measurements below, bottlenose dolphin 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

|  | bottlenose dolphin | three-toed sloth |
| --- | --- | --- |
| Mass | 150–650 kg | 2.2–6.3 kg |
| Length | 2–4 m | 0.42–0.8 m |
| Top speed | 35 km/h | 0.24 km/h |
| Lifespan | 30–60 yr | 20–40 yr |

## Where each one leads

- Mass: bottlenose dolphin is 75× heavier.
- Length: bottlenose dolphin is 4.5× longer.
- Top speed: bottlenose dolphin is 146× faster.
- Lifespan: bottlenose dolphin is 1.3× 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 bottlenose dolphin bigger than a three-toed sloth?

bottlenose dolphin is heavier — 150–650 kg against 2.2–6.3 kg.

### Who would win, a bottlenose dolphin 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.
