What's the difference between slow-worms and snakes?

  • Snakes and slow-worms are both reptiles but are very different.

  • Slow-worms are not worms at all (and certainly not snakes) but are legless lizards.

  • Like lizards, slow-worms have eyes that they can close. Snakes do not have eye lids.

  • Snakes do not have external ears, while slow-worms have visible ears.

  • A slow-worm, like a lizard, can lose its tail and re-grow it. A snake cannot.

  • In the UK, we have grass snakes, smooth snakes (athough they are rare) and adders. Adders can bite humans. Slow-worms do not bite.
