Species: R. decollata
Rumina decollata (vernacular English name: decollate snail) is a predatory snail native to the Mediterranean area, but it has been introduced to Britain and parts of the US as well. Notable for its truncated shell, it is related to tropical snails such as Subulina octona. Both in the wild and in captivity it is almost exclusively nocturnal and will become active during rainfall, spending the rest of time burrowed in the ground. It preys on other snails and slugs (most notably Cornu aspersum), their eggs, and other invertebrates; as such it is used as a natural pest control agent in gardens.
