The overall topography of Siberia devides rather neatly into
three broad horizontal zones.
To the north lies a great treeless tundra, extending along
the whole Arctic coast from Novaya
Zemlya to Bering Strait; through the middle streched a broad
belt of forest from the Ural
Mountains to the Okhotsk Sea; and to the south, arable land
that shades into semi-aric desert
steppes from the southern Urals to beyond the Mongolian frontier.

Siberia. Large mountain ranges cut across it to the south
and east, majestic volcanoes on its
far horizons formed part of the Pacific rim of fire, and its
mighty rivers, rivals to the Mississippi
and the Nile, could, if linked together, encircle the globe
twenty-five times.
Each one of its three majour river basisns is larger than
the whole of Western Europe.
In climate, it ranges from the Arctic to the semi-tropical,
supports animals as divers as
camels and polar bears.
Siberia. 5.000.000 square miles, or about 7.5 % of the toal
land surface of the globe.
If it were possible to move entire countries from one part
of the globe to another, you could
take the whole of United States of America, and set it down
in the middle of Siberia, without
touching anywhere the boundaries of the latter teritory. You
could then take Alaska and all
the States of Europe, with the single exception of Russia,
and fit them into the remaining
margin and after having done that, you would still have more
than 300.000 square miles of
Siberian territory to spare.
Siberia. The name itself is a mystical term, derived from
the Mongolian
siber (beautiful,
wonderful, and pure), and the Tartar
sibir, which means
'the sleeping land'.
The sleeping beauty at its heart is Lake Baikal, the oldest
lake in the world, the largest fresh-
water lake by volume, (with about a fifth of the fresh water
on the surface of the globe),
and the deepist continental body on earth. Fed by some 336
tributary rivers and streams,
it formes a crescent nearly 400 miles long, yet had once an
isolated ecosystem comparable to
that of the Galapagos Islands.
Of its 1,700 indigenous species of plant and animal life,
1,200 were unique - including a fish
called the golomyenka, which gave birth to live young. Baikal
also had once tens of
thousands of fresh-water seals - although the nearest ocean
was 1,000 miles away.

Golomyanka (fat fish), Comephorus
dybowskii.
The most interesting of bullheads are these fishes.
The Lake wonder! Golomyanka
can be found nowhere else on the earth. It is unusually
beautiful, sparkles blue and
pink in sunshine. However, the sunshine causes it
to melt! Only bones and a fat spot
will be left there.
It contains about 30% of oil, rich in vitamin «A».
There was a time when Tibetian
monks came to Baikal and gathered golomyanka along
the shores. Its fat was used
as a remedy for many diseases. Native Siberians used
it as the fuel for their lamps,
and also medicinally.The fat was was used in treatments
for rheumatism,
atherosclerosis and for healing wounds.

Golomyanka is the main and the most numerous
inhabitant of Baikal, but it very
seldom gets into fishermen's nets. Its resources amount
for about 150 thousand tons,
but on neither of its life stages does it swim in
great gatherings, and, that's why,
it's not entered in the food-fish list. Its predator
is nerpa (the Baikal seal),
for which golomyanka is the staple diet.
Golomyanka is a very independent fish and quite different
from its relatives who
tend to shoal. It prefers a solitary existence. Golomyanka
fish lives down in the depth
of the Lake between 700-1600 feet deep where the water
temperature is low.
It is noted that the golomyanka is very sensitive
to the temperature of water.
The temperature of up to +5°C is optimal for it,
it avoids higher temperatures,
and +10°C is mortal for it.
This fish is small in size, 15-20 cm long. It's designed
to live in extreme pressures.
Interesting are vertical migrations of Golomyanka
from small depth to bottoms of very
deep depressions. At night Golomyanka rises to the
water surface, and at daytime
it swims down to great depths.
Each autumn the females being viviparous instead of
laying eggs produce 2000-3000
of larvae ready to swim progeny and after that they
generally die.
