A new species of translucent snail has been discovered in the deepest cave in Croatia. The cave system, Lukina Jama–Trojama in Croatia, is one of the 20 deepest in the world.

Zospeum tholussum translucent snail shell


The new species, Zospeum tholussum, is a tiny snail with a beautiful dome-like translucent shell. Only one living specimen was found during the expedition into the cave system. The animal was found at the remarkable depth of 980 m, in an unnamed chamber full of rocks and sand and a small stream running through it.

The research was published here in Subterranean Biology.
