Transparent shell snail discovered in Croatia

Leave a Comment
It was discovered a transparent shell snail within the deepest cave of Croatia. The little creature was declared as a new species and lives in one of the 20 deepest caves systems of the Lukina Jama-Trojama â€" world.

The newfound species â€" zospeum tholussum â€" belongs to a genus of snail who cannot see and that only lives in dark underground caves. The most distinctive aspect of the fragile animal is its beautiful shell, translucent, cone-shaped.

Scientists found only one live specimen during his expedition. The animal was discovered a remarkable depth of 980 metres, in a Chamber full of stones and sand with a small stream.

All the known species of the cave have a limited capacity for locomotion. But their preference for a muddy habitat and establish generally close the drainage system of the cave, in proximity to the water, suggests that these animals are not real estate.

The scientists think that the dispersion of snails is obtained by your movement through the water or for driving larger mammals.

Lukina Jama-Trojama is the deepest cave in Croatia and is known for its extraordinary vertical form, long chasms and great depth-at least 1,392 meters.

From an ecological point of view, this cavernous system is extremely interesting for having three layers microclimatic: a piece of ice that forms at the entrance, with a temperature of about 1° C; the middle part, with temperatures up to 2ºc; and the bottom with a temperature of 4ºc.

These unusual living conditions make the cave extremely interesting for scientists from the point of view of its biodiversity.
