# black mamba vs Komodo dragon

**black mamba vs Komodo dragon: Komodo dragon leads on 2 of 3 measures**

Measured comparison — not a prediction

The fastest snake and Africa's longest venomous one; it is named for the black inside of its mouth, not its colour. The largest living lizard, which kills large prey with venom and shock rather than jaw power. On the measurements below, Komodo dragon 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

|  | black mamba | Komodo dragon |
| --- | --- | --- |
| Mass | 1–3.1 kg | 40–166 kg |
| Length | 2–4.3 m | 2–3.13 m |
| Top speed | 11–20 km/h | — |
| Bite force | — | 39 psi |
| Lifespan | 10–20 yr | 25–35 yr |

## Where each one leads

- Mass: Komodo dragon is 44× heavier.
- Length: near enough identical.
- Lifespan: Komodo dragon is 2.7× 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 black mamba bigger than a Komodo dragon?

Komodo dragon is heavier — 40–166 kg against 1–3.1 kg.

### Who would win, a black mamba 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.
