# American alligator vs Komodo dragon

**American alligator vs Komodo dragon: American alligator leads on 4 of 4 measures**

Measured comparison — not a prediction

A broad-snouted crocodilian of the US Southeast, recovered from near-extinction to over a million animals. The largest living lizard, which kills large prey with venom and shock rather than jaw power. On the measurements below, American alligator 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

|  | American alligator | Komodo dragon |
| --- | --- | --- |
| Mass | 70–500 kg | 40–166 kg |
| Length | 2.6–4.6 m | 2–3.13 m |
| Bite force | 1,000–2,980 psi | 39 psi |
| Lifespan | 35–70 yr | 25–35 yr |

## Where each one leads

- Mass: American alligator is 3.3× heavier.
- Length: American alligator is 1.4× longer.
- Bite force: American alligator is 54× a stronger bite.
- Lifespan: American alligator is 1.7× 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 American alligator bigger than a Komodo dragon?

American alligator is heavier — 70–500 kg against 40–166 kg.

### Who would win, a American alligator or a Komodo dragon?

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.
