# great hammerhead vs green anaconda

**great hammerhead vs green anaconda: great hammerhead leads on 2 of 3 measures**

Measured comparison — not a prediction

The largest hammerhead, whose broad head spreads its electroreceptors for finding buried rays. The heaviest snake in the world, though the reticulated python grows longer. On the measurements below, great hammerhead 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

|  | great hammerhead | green anaconda |
| --- | --- | --- |
| Mass | 150–580 kg | 30–227 kg |
| Length | 2.7–6.1 m | 3–8.8 m |
| Lifespan | 20–44 yr | 10–30 yr |

## Where each one leads

- Mass: great hammerhead is 3.8× heavier.
- Length: green anaconda is 1.3× longer.
- Lifespan: great hammerhead is 3.0× 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 great hammerhead bigger than a green anaconda?

great hammerhead is heavier — 150–580 kg against 30–227 kg.

### Who would win, a great hammerhead or a green anaconda?

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.
