1. Russian desman

Desman, either of two species of amphibious Eurasian moles that den on land but seek prey underwater instead of burrowing through soil. The protruding flexible snout is flat and grooved with a lobed tip. Desmans have tiny eyes and no external ears; the ear holes and nostrils close underwater. The forefeet are partially webbed and fringed with stiff hairs. The huge hind feet are webbed to the tips of the digits and are also fringed with hair. Claws are long, curved, and sharp. Both species have water-repellent fur that is long, soft, and dense.

The tail of the Russian desman (Desmana moschata) is flattened horizontally and has scent glands at its base that exude a strong musky odour that envelops the animal. The Pyrenean desman (Galemys pyrenaicus) of western Europe has similar scent glands. It has a cylindrical tail, flat near its tip and fringed with stiff hairs. The Russian desman resembles a muskrat, weighing 100–220 grams (3.5–7.8 ounces), with a body about 20 cm (8 inches) long and a tail of about the same length. Upperparts are dark brown; underparts are silvery grey. The smaller Pyrenean desman weighs 35–80 grams (1.23–2.82 ounces), with a body 11–14 cm (4–6 inches) long and a longer tail (12–16 cm; 5–6 inches). It is greyish brown above and silvery-grey beneath.

The Russian desman is nocturnal and inhabits unpolluted lakes, ponds, and slow-moving streams and rivers. It swims propelled by its hind feet and tail, using its mobile proboscis-like snout to thrust and probe along the bottom for insects, crustaceans, mollusks, fish, and amphibians. Dens are constructed in stream banks and lake margins. A tunnel with an underwater entrance leads to a nest chamber above the water level. One or two litters of two to five young are usual; gestation lasts 40–50 days. The Russian desman is indigenous to southwestern Russia, Ukraine, and Kazakhstan in basins of the Don, Volga, and Ural rivers. It has been introduced into the catchments of the Ob and Dnieperrivers of northern Russia and Ukraine, respectively. Populations have declined to owe to excessive trapping for fur, water pollution, and competition for space with introduced muskrats and nutrias.

The nocturnal Pyrenean desman prefers cold, clear, and swift mountain streams and rivers at elevations from 300 to 2,200 metres (1,000 to 7,200 feet). Although awkward on land, it is an adept, fast swimmer, propelling itself primarily by its strong hind legs and feet. During the day it shelters in crevices among stones and roots in stream banks or burrows constructed by water voles. Litters of one to five young are born after a gestation of 30 days. Aquatic insect larvae and nymphs, crustaceans, and sometimes fish make up its diet. The Pyrenean desman inhabits the Pyrenees Mountains and the northern mountains of the Iberian Peninsula. It is threatened by stream pollution and other manmade alterations of its habitat.

Desmans are a subfamily (Desmaninae) of moles (family Talpidae, order Soricomorpha), which belong to a larger group of mammals referred to as insectivores. Other Eurasian species of Desmana and Galemys evolved and then went extinct during the Pliocene Epoch (5.3 million to 2.6 million years ago).

2. Putorana snow sheep

There are only five entries for the Putorana snow sheep in the SCI Record Book; three of which were taken on an unchartered expedition in August 1995, one in August 1996 and the last in July 2000. The city of Norilsk was closed in November 2001 to all non-Russians, except for Belarusians. Nickel ore is smelted on-site at Norilsk. The smelting is directly responsible for severe pollution, generally acid rain and smog. By some estimates, 1% of global emissions of sulfur dioxide come from there. Norilsk is recognized by the Russian Government as the most polluted city in the entire country. Mining and smelting ore are the major industries and Norilsk is the centre of a region where nickel, copper, cobalt, platinum, palladium and coal are mined.

3. Ross’s Gull

The Ross’s gull (Rhodostethia rosea) is a small gull, the only species in its genus, although it has been suggested it should be moved to the genus Hydrocoloeus, which otherwise only includes the little gull. This bird is named after the British explorer James Clark Ross. Its breeding grounds were first discovered in 1905 by Sergei Aleksandrovich Buturlin near the village of Pokhodsk in North-Eastern Yakutia while visiting the area as a  judge. The genus name Rhodostethia is from Ancient Greek rhodon, “rose”, and stethos, “breast”. The specific rosea is Latin for “rose-coloured”.

This small bird is similar in size and some plumage characteristics to the little gull. It is slightly larger and longer winged than that species and has more-pointed wings and a wedge-shaped tail. Its legs are red. Summer adults are pale grey above and white below, with a pink flush to the breast, and a neat black neck ring. In winter, the breast tints and neck collar are lost and a small dark crescent develops behind the eye.

Young birds resemble winter adults, but have a dark “W” pattern on the wings in flight, like young little gulls. The juveniles take two years to attain full adult plumage.

Ross’s gull breeds in the high Arctic of northernmost North America, and northeast Siberia. It migrates only short distances south in autumn, most of the population wintering in northern latitudes at the edge of the pack ice in the northern Bering Sea and the Sea of Okhotsk, although some birds reach more temperate areas, such as north-west Europe; in February 2016 they were sighted in Cornwall and Ireland according to the BTOs ‘BirdTrack’. In North America, Ross’s gull has been spotted as far south as the Salton Sea in California, although sightings this far south are extremely rare. The summer breeding grounds are tundra with sedges, grass tussocks, dwarf willows, bushes, lichens and pools.

4. Amur lemming

“The Amur lemming (Lemmus amurensis) is a species of lemmings found near the Amur River in Siberia. The Amur lemming is rated as Least Concern on the IUCN Red List”
So, you have a big change to meet a real one in nature.

5. Siberian crane

The Siberian crane (Leucogeranus leucogeranus), also known as the Siberian white crane or the snow crane, is a bird of the family Gruidae, the cranes. They are distinctive among the cranes, adults are nearly all snowy white, except for their black primary feathers that are visible in flight and with two breeding populations in the Arctic tundra of western and eastern Russia. The eastern populations migrate during winter to China while the western population winters in Iran and formerly, in India and Nepal. Among the cranes, they make the longest distance migrations. Their populations, particularly those in the western range, have declined drastically in the 20th century due to hunting along their migration routes and habitat degradation. The world population was estimated in 2010 at about 3,200 birds, mostly belonging to the eastern population with about 95% of them wintering in the Poyang Lake basin in China, a habitat that may be altered by the Three Gorges Dam. In western Siberia, there are only around ten of these cranes in the wild.

Adults of both genders have a pure white plumage except for the black primaries, alula and primary coverts. The fore-crown, face and side of the head is bare and brick red, the bill is dark and the legs are pinkish. The iris is yellowish. Juveniles are feathered on the face and the plumage is dingy brown. There are no elongated tertial feathers as in some other crane species. During the breeding season, both the male and female cranes are often seen with mud streaking their feathers. They dip their beaks in mud and smear it on their feathers. The call is very different from the trumpeting of most cranes and is a goose-like high pitched whistling Toyota. They typically weigh 4.9–8.6 kg (11–19 lb) and stand about 140 cm (55 in) tall. The wingspan is 210–230 cm (83–91 in) and length is 115–127 cm (45–50 in). Males are on average larger than females. There is a single record of an outsized male of this species weighing 15 kg (33 lb).

6. Barguzin sable

The sable (Martes zibellina) is a species of marten, a small carnivorous mammal primarily inhabiting the forest environments, of Russia, from the Ural Mountains throughout Siberia, and northern Mongolia. Its habitat also borders eastern Kazakhstan, China, North Korea and Hokkaidō, Japan. Its range in the wild originally extended through European Russia to Poland and Scandinavia. Historically, it has been hunted for its highly valued dark brown or black fur, which remains a luxury good to this day. While hunting is still common in Russia, most fur on the market is now commercially farmed.

The name sable appears to be of Slavic origin and entered most Western European languages via the early medieval fur trade. Thus the Russianсоболь (Sobol) and Polish soból became the German Zobel, Dutch Sabel; the French zibeline, Spanish cibelina, cebellina, Finnish soopeli, Portuguesezibelina and Mediaeval Latin zibellina derive from the Italian form (zibellino). The English and Medieval Latin word sabellum comes from the Old Frenchsable or saible.

The term has become a generic description for some black-furred animal breeds, such as sable cats or rabbits, and the colour black in heraldry.

7. Black-capped marmots

Black-capped marmots live in the cold and somewhat hostile alpine areas of eastern Siberia and Kamtchatica. Their closest relatives are probably the Alaska marmot, found in the Brooks Range. Black-capped marmots currently live in three very isolated and spatially distinct populations. A common feature in all habitats is the plethora of rocks and dirt of vegetation. They are only active about three and a half months each year and they mature slowly.

8. Spoon-billed sandpiper

This species was first described by Linnaeus in his Systema Naturae in 1758 as Platalea pygmea. It was later moved to Eurynorhynchus by Sven Nilsson in 1821. It is now classified under the calidrid sandpipers.

The most distinctive feature of this species is its spatulate bill. The breeding adult bird is 14–16 cm in length and has a red-brown head, neck and breast with dark brown streaks. It has blackish upperparts with buff and pale rufous fringing. Non-breeding adults lack the reddish colouration but have pale brownish-grey upperparts with whitish fringing to the wing-coverts. The underparts are white and the legs are black.

The contact calls of the spoon-billed sandpiper include a quiet preep or a shrill wheer. The song, given during display, is an intermittent buzzing and descending trill preer-prr-prr. The display flight of the male includes brief hovers, circling and rapid diving while singing.

9. Baikal seal

The Baikal seal, Lake Baikal seal or nerpa (Pusa sibirica), is a species of earless seal endemic to Lake Baikal in Siberia, Russia. Like the Caspian seal, it is related to the Arctic ringed seal. The Baikal seal is one of the smallest true seals and the only exclusively freshwater pinniped species. A subpopulation of inland harbour seals living in the Hudson’s Bay region of Quebec, Canada (lac de loups marins harbour seals), the Saimaa ringed seal (a ringed seal subspecies) and the Ladoga seal (a ringed seal subspecies) are found in freshwater, but these are part of species that also have marine populations. The ancestor of the Baikal seal migrated into Lake Baikal from the Arctic (via the Siberian ice sheet) and became isolated there.

The most recent population estimates are 80,000 to 100,000 animals, roughly equaling the expected carrying capacity of the lake. At present, the species is not considered threatened, despite hunting (both legal and illegal) and pollution of the lake.

The Baikal seal lives only in the waters of Lake Baikal. It is something of a mystery how Baikal seals came to live there in the first place. They may have swum up rivers and streams or possibly Lake Baikal was linked to the ocean at some point through a large body of water, such as the West Siberian Glacial Lake or West Siberian Plain, formed in a previous ice age. The seals are estimated to have inhabited Lake Baikal for some two million years.

The areas of the lake in which the Baikal seals reside change depending on the season, as well as other environmental factors. They are solitary animals for the majority of the year, sometimes living kilometres away from other Baikal seals. In general, a higher concentration of Baikal seals is found in the northern parts of the lake, because the longer winter keeps the ice frozen longer, which is preferable for pupping. However, in recent years, migrations to the southern half of the lake have occurred, possibly to evade hunters. In winter, when the lake is frozen over, seals maintain a few breathing holes over a given area and tend to remain nearby, not interfering with the food supplies of nearby seals. When the ice begins to melt, Baikal seals tend to keep to the shoreline

10. Orlov Trotter

The Orlov Trotter is a horse breed with a hereditary fast trot, noted for its outstanding speed and stamina. It is the most famous Russian horse. The breed was developed in Russia in the late 18th century by Count Alexei Orlov at his Khrenovskoy stud farm near the town of Bobrov (Voronezh Guberniya). The Orlovs emerged as the result of crossing various European mares (primarily of English, Dutch, Mecklenburg, and Danish breeding) with Arabian stallions.

During the 19th century, Orlov trotters were used mainly for riding and harness racing by Russian nobility. They were valued for their beauty and elegance combined with the ability to work hard. They were also used for the improvement of other Russian horses. When harness racing became widespread at the end of the century, the Orlovs faced intense competition from American-developed Standardbreds, who are generally recognized as less refined but faster than Orlov trotters. Eventually, Standardbred stallions were crossed with Orlov mares and a new breed, the Russian Trotter, appeared. The possibility of the complete extinction of the Orlovs was a concern in the 20th century because of crossbreeding and the Sovietdisregard of horse-raising. However, the breed survived, and today fifteen stud farms in Russia and Ukraine raise pure-blooded Orlov Trotters.

The land that became Orlov’s Khrenovsky stud farm was given to him by Catherine II (Catherine the Great) as a reward for his participation in the coup d’etat which brought her to the throne. The buildings were constructed by Giovanni Giliardi. The original estate was very large; the modern Khrenovsky stud area is fifteen times smaller than it was before the Bolshevik revolution.

The ancestor of all Orlov Trotters was the purebred grey Arabian stallion Smetanka. Orlov bought him in Turkey for the enormous sum of 60,000 rubles. Although he died the next year, he lived to sire five offspring. Among others, he was crossed with Isabelline, a Danish mare from the Frederiksborg royal stud-farm, who foaled a stallion that was named Polkan (1778–1793).

Polkan was crossed with a Dutch mare which, in 1784, produced the grey stallion Bars I (1784–1808), considered the first Orlov trotter. He was 162.5 cm high at the withers which made him taller than most contemporary trotters, possessed a fast trotting gait and featured the beauty and noble bearing which would later distinguish the newly created breed. For seventeen years Bars, I was crossed with different mares and sired eleven stallions that carried his distinguishing characteristics. The emergence of the breed was the result of a thorough and elaborate selection process. About 3,000 horses kept at the stud were involved. Unlike many other Russian nobles who were fond of horse-raising, Orlov was a professional breeder who is also credited for creating some seventy different animal breeds including the Russian wolfhound.

Orlov was very protective of his bloodstock and would sell only geldings (castrated stallions). Even when Tsar Alexander I asked Orlov to sell him several stallions, Orlov only agreed to sell geldings. This rule was maintained for twenty years after Orlov’s death. Later, when the Khrenovsky stud farm belonged to the Russian Crown, Trotters were then openly sold to private stud-owners.
