It seems that there's something new on the zombie monster front - at least, in the UK.
Blind, deathly white and with a full set of razor-sharp teeth it is like a creature from a B movie horror film.
But for gardeners in Wales the albino ghost slug, which devours worms and sucks them up like spaghetti, is all too real.
The bizarre creature, which is similar to a species found lurking in caves in Turkey and Georgia, is completely white and has no eyes.
According to biologists, the slug has never been seen before in Western Europe, biologists say, and they are amazed that it has turned up in a garden in Caerphilly, north Wales.
A spokeswoman for the National Museum in Cardiff said it's a mystery how the slug got to Britain.
She added "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, is completely white, and lives underground, squeezing its flexible body into cracks to get at the worms.'
Sounds scary! I think I'm going to try to find a few for a young schoolboy I know. He keeps wanting to try new bugs in his ant farm . . .
