The epikarst is defined as the heterogeneous interface between unconsolidated material (soil, sediments and modified carbonate rock) that is partially saturated with water and capable of delaying or storing water and locally rerouting vertical infiltration to the deeper regional phreatic zone of the karst aquifer (

We believe that the amplified flow of water from the epikarst has washed out few specimens that were carried out to the travertine pools. In the other episodes in which we have visited the cave, the travertive pools were almost empty, clearly indicating that they are not persistent habitats, thus, incapable to maintain populations.
