# giant Pacific octopus vs great white shark

**giant Pacific octopus vs great white shark: great white shark leads on 2 of 2 measures**

Measured comparison — not a prediction

The largest octopus species, with three hearts, blue blood and about 2,000 suckers. The largest predatory fish, and the species responsible for most unprovoked shark bites on humans. On the measurements below, great white shark 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

|  | giant Pacific octopus | great white shark |
| --- | --- | --- |
| Mass | 10–71 kg | 520–2,000 kg |
| Length | — | 3.4–6.1 m |
| Top speed | — | 25–40 km/h |
| Bite force | — | 4,000 psi |
| Lifespan | 3–5 yr | 50–73 yr |

## Where each one leads

- Mass: great white shark is 67× heavier.
- Lifespan: great white shark is 18× 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 giant Pacific octopus bigger than a great white shark?

great white shark is heavier — 520–2,000 kg against 10–71 kg.

### Who would win, a giant Pacific octopus or a great white shark?

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.
