Nestled in the heart of the Caucasus Mountains, the Krubera Cave system is not just a record-breaking geological formation - it's a unique ecosystem that has evolved in isolation for millions of years. This subterranean world, shielded from the sun's rays and surface climate changes, offers a rare glimpse into life adapted to extreme environments.
