Ghostly slug eats worms by sucking them like spaghetti

Gardeners in south Wales should not be surprised if they find an all-white, worm-munching slimy creature in their flowerbeds this summer.

A "ghost" slug found in a garden in Cardiff has been declared a new species by specialists at the National Museum of Wales and Cardiff University. They have given the creature a partially Welsh name, Selenochlamys ysbryda, or ghost (ysbryd) slug. Creatures of this type are more usually found in Turkey and Georgia.

The origin of the ghost slug, and its route into Britain, is completely unknown, and specimens have not been seen in Europe before this was discovered in Cardiff last year. Another was was spotted in nearby Caerphilly.



Unlike most slugs, the ghost slug is carnivorous and kills earthworms at night with powerful, blade-like teeth, sucking them in like spaghetti. It has no eyes or bodily colouring and lives underground.

"The Ghost Slug belongs to an obscure and almost unpronounceable group of slugs - the Trigonochlamydidae," said Ben Rowson, a biologist at National Museum Cardiff.

"We had to thumb through lots of old publications in Russian and German to find anything like them - but then discovered they were something entirely new." After studying the slug's anatomy, the scientists realised it was an undescribed species and christened the creature with the name adapted from the Welsh word for ghost, ysbryd.
