Sarma Cave (Georgian: სარმის მღვიმე), located in the Gagra District of Abkhazia, a breakaway region of Georgia, is the third-deepest recorded cave in the world. Its depth (1830 m) was measured in 2012 by a team led by Pavel Rudko.
The cave was discovered in 1990 by caver Sergey Shipitsin during a research expedition of the Arabika caving club from Irkutsk, led by Alexander Osintsev.
Two species of stygobiont amphipods have been found: Zenkevitchia sandroruffoi, living at depths of no more than -350 m and found in other caves of eastern Arabika Massif, in Troika Cave (at -30 m) and in Eagle's Nest Cave (-75 m); and Adaugammarus pilosus, inhabiting aquatic biotopes in the deep part of the cave (elevations -1270 m and -1700 m).
