Lake Baikal

Located in south-east Siberia, the 25 million year old Lake Baikal is the oldest and the deepest (around 1640 meters) lake in the world. It contains 20% of the world’s total unfrozen freshwater reserve. Also known as the ”Galapagos of Russia” its age and isolation has produced one of the world’s richest and most unusual freshwater faunas.Two thirds of the plants and animals that Lake Baikal has to offer are completely unique and can be found nowhere else in the world. Baikal is also recognized as one of the most clearest lakes in the world where almost all tourist who visit the place are stunned by the clear water. When in Russia you should definitely visit this place. In winter time, the lake is covered by the thick layer of ice, so people often make roads over the lake for shortcuts, but you can also find some creative drawings (see the pictures below).
The largest fish in Baikal is the sturgeon (Acipenser baerri baicalensis), which grows 1.8m (6ft) long and weighs more than 100kg (2201bs), also well known in Baikal world are the Baikal Seal or nerpa (Pusa sibirica), omul (Coregonus autumnalis migratorius), Baikal oil fish or golomyanka (Comephorus baicalensis), the Baikal grayling (Thymallus arcticus baicalensis). Nerpa is one of only three entirely freshwater seal populations in the world, the other two being subspecies of Ringed Seal.
