A new snail species with a beautifully translucent shell was recently discovered more than 3,000 feet (914 meters) underground in a Croatian cave.
The team presented the elegant snail to taxonomist Alexander Weigand at Goethe-University in Frankfurt, Germany, for help in identification. Weigand determined that this particular species had never before been found, but that it is related to other known species.
The new snail and other related species are particularly slow-moving, even by snail standards.
“They only creep a few millimeters or centimeters a week, and mainly in circles, grazing at one point where they live,” Weigand said.
Weigand suspects that the snail travels in water currents or catches a ride on other cave animals, such as bats or crickets, to get from one place to another more efficiently.
The species is described this week in the journal Subterranean Biology.
