Fun Facts

  • The Spanish slug probably originated in France. It was first found in Germany in 1969 and thus belongs to the non-native species (neozoa).

  • It is now one of the most common snails in Germany. It has largely displaced the native red slug.

  • It causes major damage to fields and gardens and is considered an economically important pest.

  • Like all air-breathing land snails, it is a hermaphrodite, i.e. it has male and female sexual characteristics.

  • Besides fresh plant parts, it feeds mainly cannibalistically.

  • As its slime tastes bitter, it has hardly any natural predators. Only some species of domestic ducks and the leopard slug eat them.

  • Endangerment level Germany: not evaluated
