The ghost slug, ''Selenochlamys ysbryda'', is a species of predatory air-breathing land slug. It is a shell-less pulmonate gastropod mollusc in the family Trigonochlamydidae. The species was first recognised from various sites in Wales and was formally described and named in 2008 by Ben Rowson, a taxonomist at the National Museum Wales ''(Amgueddfa Cymru)'', and Bill Symondson, an ecologist at Cardiff University. It has subsequently turned up at numerous further sites in South Wales and a few sites in England, but it is believed to be an introduction in the UK, occurring mostly in gardens. Specimens likely to be this species have also now been identified from two sites in natural mountain forest in the Crimea in Ukraine. Probably the Crimean mountains are within its native range. == Description and ecology == This slug can reach in size, with its body extended. It has no eyes, and is white in colour. It is predominantly burrowing, living up to a metre underground, and rarely, at night, coming to the surface.〔 Unlike the majority of slugs, it is a carnivore, feeding on earthworms using its blade-like teeth.〔(Worm-eating slug found in garden (video) ), BBC News. Published 10 July 2008. Retrieved 10 July 2008.〕 Both the mantle and the breathing hole are found at the tail end of the body.〔(Help us find out more about the mysterious alien "Ghost Slug" )〕 Because of the slug's white colour and nocturnal habits, and because it is so rarely seen, it was given the species name ''ysbryda'', the word ''"ysbryd"'' meaning ghost in the Welsh language. This in turn gave rise to the common name, "ghost slug". This appears to be the first case of a species name having been taken from the Welsh language. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Ghost slug」の詳細全文を読む スポンサード リンク
