Sarma Cave (Georgian: სარმის მღვიმე), located in Gagra District of Abkhazia,[note 1] a breakaway region of Georgia, is the third deepest recorded cave in the world. Its current depth (1830 m) was measured in 2012 by a team led by Pavel Rudko.
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).
- The political status of Abkhazia is disputed. Having unilaterally declared independence from Georgia in 1992, Abkhazia is formally recognised as an independent state by 5 UN member states (two other states recognised it but then withdrew their recognition), while Georgia continues to claim it as part of its own territory, designating it as Russian-occupied territory.
