Which cave in Abkhazia is the deepest known cave in the world and hosts unique cave fauna? The answer is Krubera Cave.
Also called Voronya Cave, it lies in the Arabika Massif of Abkhazia, in the Western Caucasus. Its deepest explored point exceeds 2,000 meters below the entrance, making it the world’s deepest known cave.
Krubera Cave supports a distinctive subterranean ecosystem. Researchers have documented numerous arthropods, including endemic springtails, beetles, spiders, crustaceans, and other organisms adapted to permanent darkness.
The cave’s fauna includes species with reduced or absent eyes and little pigmentation. Kruberia abchasica, an amphipod crustacean, has been recorded in the cave’s deepest submerged sections. Veryovkina Cave is also exceptionally deep, but it is not currently the deepest known cave.
