Scientists digging in one of the world's deepest cave systems have discovered a new type of snail with a transparent shell.

Only a single living specimen of Zospeum tholussum was found at a depth of 980m in the Lukina Jama–Trojama cave system, in Croatia.

They cannot see and can hardly move on their own.

Scientists from the Croatian Biospeleological Society and Goethe University, Frankfurt, who found the snail, believe it gets around by floating in streams of water, or attaching itself to larger creatures inhabiting the cave.
