# green anaconda vs polar bear

**green anaconda vs polar bear: polar bear leads on 2 of 3 measures**

Measured comparison — not a prediction

The heaviest snake in the world, though the reticulated python grows longer. The largest living land carnivore, classified as a marine mammal because it hunts from sea ice. On the measurements below, polar bear 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

|  | green anaconda | polar bear |
| --- | --- | --- |
| Mass | 30–227 kg | 150–700 kg |
| Length | 3–8.8 m | 1.8–3 m |
| Height | — | 1–1.6 m |
| Top speed | — | 40 km/h |
| Bite force | — | 1,200 psi |
| Lifespan | 10–30 yr | 20–32 yr |

## Where each one leads

- Mass: polar bear is 7.5× heavier.
- Length: green anaconda is 1.9× longer.
- Lifespan: polar bear is 2.5× 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 green anaconda bigger than a polar bear?

polar bear is heavier — 150–700 kg against 30–227 kg.

### Who would win, a green anaconda or a polar bear?

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.
