|Testacella haliotidea Draparnaud|
A Leopard Slug is omnivorous, eating other small slugs. But mostly eats fungus and OM.
Leopard slugs are know vectors of meningitis (just don’t eat them raw). This photo is from the AUB worm farm.
Probably not an issue and not a plant eater.

This carnivorous semi-slug
Worm-Eating Slugs (Testacella species, Family Testacellidae): Found in Europe, Africa, Britain, and Islands in the North Atlantic. These slugs with a shell (yeah, they are still called slugs, not snails) primarily eat earthworms and live most their lives underground. There are some reports of these slugs eating insect larvae as well.
Ghost Slug (Selenochlamys ysbryda, Family Trigonochlamydidae): Found in the UK and Europe down to Turkey. Also a earthworm eater.
