Greece that is rich in limestone numbers about 10.000 caves. The most popular and famous ones are the caves of Diros in the Laconian part of Mani. The interior of these caves is beautifully decorated with stalactites and stalagmites. Thousands of Greek and foreign tourists visit them yearly.
The Taygetos Mountains that are also rich in limestone boast of some dozens of extremely beautiful caves. Different scientists are engaged in studying them.
Most of these caves were formed as a result of rainfalls and complex processes of snow melting and movement of the underground waters. There are 116 caves of this type and 22 underground rivers.
As for the organisms that inhabit the caves one should distinguish the ones that live only inside the caves, those that can live both outside and inside and the ones that got inside the caves as a result of some accident.
