Lake Baikal is an amazing feature of Nature. It is situated in the centre of the Asian continent. The lake is unique in all respects.
It is the oldest lake – it is 20-30 million years, and it is capacious – it can hold the waters of the Baltic Sea and those of the five Great American Lakes. It is also the biggest lake – it is equal to the territories of Belgium and Holland taken together. It is the deepest lake – its depth in some places reaches 1.634 metres. The Baikal water is the most important stock of the planet’s drinkable water, it constitutes 1 /5 of iit.
So how is the lake’s name originated? Who named it Baikal? In the Middle Ages in the Mongolian language people called it “Tengiz”, then before the Russians came Baikal was called “Baigal-dalai” or “Baigal-Muran” (dalai means sea, muran means river in the Mongolian language) or “standing fire” (Baikal- the reflection of heaven).
There are 852 species, 233 kinds of seaweeds, more than 1550 kinds of animals, 50 species of fish, nearly 600 species of plants, and 300 species of birds.
Do you know about the famous Baikal fish? Certainly it’s omul. But omul came from the ocean. How could omul reach the lake? The Baikal omul lives 5-14 years. For its reproduction the omul swims up the tributaries of Baikal: the upper Angara, the Kichera, the Selenga and other small rivers.
There is a mysterious self-bearing fish – golomyanka. It throws 2-3 thousands of larvae into the water and perishes. Its body is without scales. Its body is transparent and in light you can see its skeleton. The golomyanka’s body consists of 3% of fat. And it is used in the Tibetan medicine.
In Baikal you can find a sea animal- seal (it’s Baikal seal). It has beautiful fur and its fat has medicinal qualities. Its meat is just like chicken, the uncooked liver is rich in vitamins and they say it’s the most valuable product. The seal lives in the north and in the middle part of Baikal.
The taiga expanses surrounding Lake Baikal are famous for fur-bearing animals, such as squirrels, sables, stoats, minks, foxes, hares and others. In the taiga in the vicinity of Baikal you can meet bears, the lynx and the Siberian reindeer.
Barguzin sables have always been considered the greatest wealth of the lake Baikal area. They are beautiful and strong, especially near the lake and in places where it is colder. Their shimmering dark fur stands out for its silkiness.
Baikal’s flora
Lake Baikal and its shores have been declared a specially protected zone of our country. There is a hope that one of the most beautiful and deepest lakes in the world will never die.
