A new species of snail discovered deep in a Croatian cave has a translucent shell:
Zospeum tholussum – belongs to a genus of minute air-breathing land snails that cannot see to find their way around and are considered to be true eutroglobionts that only live in dark, underground caves.
The fragile snail has a beautifully shaped dome-like translucent shell.
Scientists from Goethe University, Frankfurt and the Biospeleological Society in Croatia, found just one living specimen during the expedition, the findings of which were published in the journal Subterranean Biology.
The animal was found at the remarkable depth of 980 metres, in an unnamed chamber full of rocks and sand with a small stream running through it.
