Wild animals (State of Oman postage stamps)

  Rhinoceros often abbreviated to rhino, is one of any five extant species of odd-toed ungulates in the family Rhinocerotidae, as well as any of the numerous extinct species. Two of these extant species are native to Africa and three to Southern Asia.

  Bison or buffalo are large, even-toed ungulates in the genus Bison within the subfamily Bovinae. Two extant and four extinct species are recognized. Of the four extinct species, three were North American: Bison antiquus, B. latifrons, and B. occidentalis. The fourth, B. priscus, ranged across steppe environments from Western Europe, through Central Asia, East Asia including Japan,[1][2] and onto North America.

  Hyenas or hyaenas are any feliform carnivoran mammals of the family Hyaenidae. With only four extant species, it is the fifth-smallest biological family in the Carnivora, and one of the smallest in the class Mammalia. Despite their low diversity, hyenas are unique and vital components of most African ecosystems.

  The moose (North America) or elk (Eurasia), Alces alces, is the largest extant species in the deer family. Moose are distinguished by the broad, flat (or palmate) antlers of the males; other members of the family have antlers with a dendritic ("twig-like") configuration. Moose typically inhabit boreal forests and temperate broadleaf and mixed forests of the Northern Hemisphere in temperate to subarctic climates.

  The wild boar (Sus scrofa), also known as the wild swine or Eurasian wild pig, is a suid native to much of Eurasia, North Africa, and the Greater Sunda Islands. Human intervention has spread its range further, making the species one of the widest-ranging mammals in the world, as well as the most widely spread suiform.

Scientific research vessel "Cosmonaut Yuri Gagarin"

  "Cosmonaut Yuri Gagarin" - scientific research vessel for controlling the spacecrafts to perform trajectory and telemetry, to liaise ground mission control points with the crews of space ships and stations. The largest and most powerful ship in its class. 
  Built in 1971 in Leningrad. Maximum length of 231.6 m, maximum width of 31.0 m, height of the board at the midsection of 15.4 m. Displacement with full stocks of 45,000 tonnes, sea gauge 8.5 m. The steam turbine power plant with capacity of 19,000 horsepower, the maximum travel speed up to 18 knots. Range continuous voyage of 20,000 miles. It has been attributed to the port of Odessa. From 1971 to 1991, the ship has fulfilled 20 cruises in the Atlantic Ocean. The main task was to control flights of satellites, manned spacecrafts and unmanned interplanetary stations.
  After the collapse of the USSR the ship passed under the jurisdiction of the Ministry of Defence. It was not used for its intended purpose and based in the port of Yuzhny near Odessa. In 1996 the ship was sold for scrap at a price of 170$ per tonne for the Austrian company "Merkur Zuid" and disposed of.

Scientific research vessel "Cosmonaut Vladislav Volkov"

  "Cosmonaut Vladislav Volkov" - scientific research vessel designed to collect telemetry data from the spacecrafts and connection of ground flight control points with the crews of space ships and stations. Built in 1977 in Leningrad, as part of a series of four ships of the project "Selena-M". 
  Maximum length of 121.9 m, maximum width of 16.7 m, height of the board to the upper deck of 10.8 m; Total displacement of 8,950 tonnes of sludge 6,6 m; Main propulsion - diesel engine capacity of 5200 liters. The speed of 14.7 knots. 
Marine reserves: oil - 1440 tons, lubricating oil - 30 tons, washing and drinking water - 600 t; Cruising range of 16 000 miles. Stocks have enough provisions for 90 days, water supplies - for 30 days. The crew consisted of 66 people, the expedition - 77 people. Navigation area seaworthy vessel is not limited. From 1977 to 1991 the ship complied with 14 expeditionary flights to Central and South Atlantic, the Gulf of Mexico, Caribbean Sea and the Indian Ocean. The main task was to ensure control of the flight control center in charge of an operation conducted on manned orbital stations, control switching booster rocket stages during the launches of geostationary satellites and satellites with highly elliptical orbits.
  In 2000, the vessel was dismantled in the Kaliningrad shipyard "Baltica".
