Amu Darya

                 Amu Darya (Amudaryo, Oxos, Амударё ,آمودریا) is a major river in Central Asia. It is formed by the junction of the Vakhsh and Panj rivers. The river's total length is 2,400 kilometres (1,500 mi) The river is navigable for over 1,450 kilometres (900 mi). All of the water comes from the high mountains in the south where annual precipitation can be over 1,000 mm (39 in). 
                 The main tributaries of Amu Darya are: Panj River, Vakhsh River, Surkhan Darya, Sherabad River, Zeravshan River. Use of water from the Amu Darya for irrigation has been a major contributing factor to the shrinking of the Aral Sea since the late 1950s.

Populus

                 Populus is a genus of 25–35 species of deciduous flowering plants in the family Salicaceae, native to most of the Northern Hemisphere. English names variously applied to different species include poplar, aspen, and cottonwood. The genus has a large genetic diversity, and can grow from anywhere between 15–50 m (50 to 165 ft) tall, with trunks of up to 2.5 m (8 ft) diameter. 
                 The genus Populus has traditionally been divided into six sections on the basis of leaf and flower characters. These are: Populus section Populus – aspens and White Poplar, Populus section Aigeiros – black poplars, some of the cottonwoods, Populus section Tacamahaca – balsam poplars, Populus section Leucoides – necklace poplars or bigleaf poplars, Populus section Turanga – subtropical poplars, Populus section Abaso – Mexican poplars.

Lake Tanganyika

                Lake Tanganyika is an African Great Lake. It is estimated to be the second largest freshwater lake in the world by volume, and the second deepest, in both cases, after only Lake Baikal in Siberia. It had a surface of 32,900 km2 (12,700 sq mi). It is also the world's longest freshwater lake. The lake is divided among four countries – Tanzania, the Democratic Republic of the Congo, Burundi, and Zambia. 
                The major river that flows into this lake is the Ruzizi River, which enters the north of the lake from Lake Kivu. The Malagarasi River, which is Tanzania's second largest river, enters the east side of Lake Tanganyika. The Malagarasi is older than Lake Tanganyika and before the lake was formed directly drained into the Congo river .

Great hammerhead shark

               Great hammerhead (Sphyrna mokarran) is the largest species of hammerhead shark, family Sphyrnidae, attaining a maximum length of 6.1 m (20 ft). It is found in tropical and warm temperate waters worldwide, inhabiting coastal areas and the continental shelf. 
                An active predator with a varied diet, known prey of the great hammerhead include invertebrates such as crabs, lobsters, squid, and octopus, bony fishes such as tarpon, sardines, sea catfishes, toadfish, porgies, grunts, jacks, croakers, groupers, flatfishes, boxfishes, and porcupine fishes, and smaller sharks such as smoothhounds.
                 With its large size and cutting teeth, the great hammerhead is certainly capable of inflicting fatal injuries to a human and caution should be exercised around them. This species has a (possibly undeserved) reputation for aggression and being the most dangerous of the hammerhead sharks.

Mount Rainier

                 Mount Rainier is a massive stratovolcano located 54 miles (87 km) southeast of Seattle in the state of Washington, United States. It is the most topographically prominent mountain in the contiguous United States and the Cascade Volcanic Arc, with a summit elevation of 14,411 ft (4,392 m). On clear days it dominates the southeastern horizon in most of the Seattle-Tacoma metropolitan area to such an extent that locals sometimes refer to it simply as "the Mountain." On days of exceptional clarity, it can also be seen from as far away as Portland, Oregon and Victoria, British Columbia. It had an elevation of 4,392 m (14,411 ft). 
                 With 26 major glaciers and 36 sq mi (93 km2) of permanent snowfields and glaciers, Mount Rainier is the most heavily glaciated peak in the lower 48 states. The Carbon, Puyallup, Mowich, Nisqually, and Cowlitz Rivers begin at eponymous glaciers of Mount Rainier.

Klarälven

                 Klarälven is a river flowing through Norway and Sweden. Together with Göta älv, which it is called as the river has passed through the lake Vänern, thus regarded as an entity, Göta älv-Klarälven is the longest river in Scandinavia and in the Nordic countries and its Swedish part the longest river of Sweden. It had a lenght of 460 km (286 mi). 
                  It emanates from Lake Rogen in Härjedalen, Sweden, and then passes through the Norwegian Hedmark, where it flows through the lake Femunden. There it is known as Femundelva and Trysilelva. The rest of the river, the longest part, flows through Värmland to ultimately discharge in a delta into Vänern at Karlstad. In its turn, Vänern drains then into Göta älv, reaching the sea at Gothenburg. Klarälven has clean and fresh water, suitable for bathing.

Tuatara

                Tuatara is a reptile that is endemic to New Zealand which, though it resembles most lizards, is part of a distinct lineage, order Rhynchocephalia. The tuatara is considered the most unspecialised living amniote. The brain and mode of locomotion resemble those of amphibians and the heart is more primitive than that of any other reptile. Tuatara are greenish brown and gray, and measure up to 80 cm (31 in) from head to tail-tip and weigh up to 1.3 kg (2.9 lb) with a spiny crest along the back, especially pronounced in males. Their dentition, in which two rows of teeth in the upper jaw overlap one row on the lower jaw, is unique among living species. 
               Adult tuatara are terrestrial and nocturnal reptiles, though they will often bask in the sun to warm their bodies. Hatchlings hide under logs and stones, and are diurnal, likely because adults are cannibalistic. Tuatara thrive in temperatures much lower than those tolerated by most reptiles, and hibernate during winter. They remain active at temperatures as low as 5 °C (41 °F), while temperatures over 28 °C (82 °F) are generally fatal.

Green Anaconda

                Green Anaconda (Eunectes murinus, water boa) is a nonvenomous boa species found in South America. It is the heaviest known snake species. The green anaconda is one of the world's longest snakes, reaching more than 6.6 m (22 ft) long. The longest (and heaviest) scientifically verified specimen was a female measuring 521 cm (17.09 ft) long and weighing 97.5 kg (215 lb). The color pattern consists of olive green background overlaid with black blotches along the length of the body.
                 The primarily nocturnal anaconda species tend to spend most of its life in or around water. Anacondas are also sometimes known as the water boa; they spend more time in water than any of the boas. Because of their large sizes, they seem rather slow and sluggish when traveling on land. They eat a wide variety of prey, almost anything they can manage to overpower, including fish, birds, a variety of mammals, and other reptiles.
