Siberian Tiger


Animal You | Siberian Tiger | The Siberian tiger is yellow or rusty red, with black stripes thin cross. The body length is not less than 150 cm (60 inches), the length of the skull condylobasal 250 mm (10 inches), zygomatic width 180 mm (7 inches) and the length of the upper carnassial tooth more than 26 mm (1 inch ) long. Generally, 5-10 cm (2-4 inches) longer than the Bengal tiger, which is about 107-110 cm (42-43 inches) tall. The measures taken by scientists Siberian Tiger Project in Sikhote-Alin range 178-208 cm (70 to 82) of the head and body length measured in a straight line, with an average of 195 cm (77 inches) males and females ranging from 167 to 182 cm (66-72 inches) with an average of 174 cm (69 inches). The tail is an average of 99 cm (39 inches) in males and 91 cm (36 inches) in females.

The longest male "Maurice" measured 309 cm (122 inches) in total length (tail of 101 cm (40 inches)) and had a circumference of 127 cm (50 inches). The longest women "Maria Ivanna" measure 270 cm (110 inches) in total length (tail of 88 cm (35 inches)) and had a circumference of 108 cm (43 inches). These measurements show that the present Amur tiger is longer than the Bengal tiger and the African lion. According to modern research of wild Siberian tigers in Sikhote-Alin, an average adult male over 35 months weighs 176.4 kg (389 lbs), the average asymptotic limit is 222.3 kg (490 lbs) adult tigress weighs 117.9 kg (260 lb). The mean weight of historical Siberian tigers is supposed to be higher: 215.3 kg (475 pounds) for males and 137.5 kg Tigers (303 lb) for women. In May 2011, a man named "Banzai" weighing 207 kg (460 lb) has a radio collar. The queue length in the mature male is about 1 m (39 inches). In some cases, Siberian tigers in captivity reached a body weight of up to 465 kg (1,030 pounds), like the tiger "Jaipur".

The skull of the Siberian tiger is distinguished by its larger overall size, as well as the development of its sagittal crest, whose height and strength exceeds that of other tigers and lions. The variation in the size of the skulls of Siberian tigers varies from 331-383 mm (13.0 to 15.1 inches) measured in nine individuals. Female skulls range from 279.7 to 310.2 mm (11.01 to 12.21 cm). Turkestan skull length men had a length of 297.0 to 365.8 mm (11.69 to 14.40 cm), while females measured from 195.7 to 255.5 mm (7.70 to 10, 06 cm). In January 1954, a dead tiger in the Kopet-Dag Sumbar had a maximum length of skull 385 mm (15.2 inches), which is considerably larger than the known maximum for this population and slightly exceeds that of most tigers in the Far East. However, it was only condylobasal length 305 mm (12.0 inches) smaller than those of the Amur tigers, with a maximum length of 342 mm recorded condylobasal (13.5 inches). The largest skull of a measure Manchuria Siberian tiger of 406 mm (16.0 inches) long, which is about 20-30 mm (0.79 to 1.2 inches) longer than the maximum length skull obtained by Amur tigers and northern India.

The background color of the layer of the Siberian tiger is often very pale, especially in the winter coat. However, variations within populations can be considerable. Compared with the population now extinct, west of summer, the Siberian tiger and the Far East winter coats contrast sharply with other subspecies. The summer coat is coarse, while the winter coat is denser, longer, softer and silky. The hair on the back summer is 15-17 mm (0.59 to 0.67 inches) long, 30-50 mm (1.2-2.0 inches) along the top of the neck, 25-35 mm (0, 98 to 1.4 inches) in the abdomen, and 14-16 mm (0.55 to 0.63 inches) tail. The skin in winter back is 40-50 mm (1.6 to 2.0 inches), 70-110 mm (2.8 to 4.3 inches) above the neck, 70-95 mm ( 2.8 to 3.7 cm) 100 throat 60 mm (2.4 to 3.9 inches) to the chest and 65-105 mm (2.6 to 4.1 inches) in the abdomen. The whiskers are 90-115 mm (3.5 to 4.5 inches). This region represents a melting zone of two biogeographic regions: East Asia coniferous and deciduous boreal complex and the complex, resulting in a mosaic of forest types varies with altitude, topography and history. Key habitats for the Amur tiger are Korean pine forests with a complex composition and structure. Sika deer are confined to the southern half of the Sikhote-Alin mountain.

The number of Amur tigers in China is estimated at 18-22. Over 90% of the population is in the region of Sikhote Alin An unknown number of surviving tigers in the reserve areas around Baekdu Mountain, based on the slopes and local observations. Siberian tigers reach sexual maturity at age four. A comprehensive genetic sampling of 95 wild tigers Russian remarkably low genetic diversity, the effective population size extremely small compared to the size of the population census, the population behaves as if it were only 27-35 people. The winter of 2006-2007 was characterized by heavy poaching. In recent years, the last viable population Siberian tiger in Russia is limited to Ussuriland. Legal tiger hunting in the Soviet Union will continue until 1947, when it was officially banned. In 1980, it was estimated that the Siberian tiger population consisted of approximately 250 animals. Traps heat detection camera installed in the DMZ in South Korea has been no tigers.

Animal You | Scorpion | Scorpions are found on all major land masses except Antarctica. The greatest diversity of scorpions in the Northern Hemisphere is in the subtropics between the latitudes 23 ° N and 38 ° N. Be found in these latitudes, the diversity, the presence north of scorpions are the Scorpion Paruroctonus Boreas north to 50 ° N. Scorpions are now in almost all terrestrial habitats, including high altitude mountains, caves and intertidal zones, found with the exception of boreal ecosystems such as the tundra, high altitude taiga and the permanently snow-capped mountains different. Five colonies of scorpions (Euscorpius flavicaudis) established themselves in Sheerness on the Isle of Sheppey in the UK. This scorpion species is small and completely harmless to humans. This marks the northern limit of where scorpions live in the wild.

Scorpions are many fossils, including the Silurian deposits, coal deposits from the Carboniferous marina and Bernstein found. The oldest known scorpions lived around 430 million years ago in the Silurian period, on the bottom of shallow tropical waters. These first scorpions had gills instead of lungs book its current form. "Currently, 111 fossil species of scorpion are known. Unusually for arachnids, there are several species of scorpion Paleozoic or Mesozoic Cenozoic that. Grow different types everywhere could Eurypterida 10 centimeters (3.9 inches) long and 2.5 m (8.2 feet). The cephalothorax, also called the prosoma comprises the carapace, eyes, chelicerae (mouth parts), pedipalps (the pedipalps of scorpions have pincers, claws or commonly called claws). And four pairs of walking legs scorpion's exoskeleton is thick and durable and offers good protection from predators. Scorpions two eyes on the upper surface of the carapace, and usually 2-5 pairs of eyes along the front corners of the cephalothorax.

The pedipalp segmented, chelate (clawed frog) is added to immobilize the prey, defense, and sensory purposes. A Scorpio called darkened or granular raised ridges linear "keel" or taxonomically keels pedipalp segments and other parts of the body that are useful. Segment 2 is the basal plate with pectins. Each of the segments 3-7 mesosomal has a pair of vents, openings for the scorpion's respiratory organs, known as the lungs of the book. This fluorescence may play a role in detecting light scorpion. Scorpions have quite variable duration and actual duration of most species is not known. Scorpions. Yes in areas where temperatures can live 20-37 ° C (68-99 ° F), but subzero temperatures to survive the desert heat Scorpiops Scorpions kind of living in the mountains can bothriurid Asian scorpions from Patagonia and small scorpions Euscorpius Central all survive winter temperatures of about -25 ° C (-13 ° F). In Repetek (Turkmenistan), there live seven species of scorpions (referred Pectinibuthus birulai is endemic) in temperatures between -31-50 ° C (-24-122 ° F).

Scorpions exhibit photophobic behavior, especially for the recognition by their enemies, such as birds, centipedes, lizards, mice, possums and rats escape. Scorpions are opportunistic predators, small arthropods, although the larger species known to kill small lizards and mice. Scorpions have an unusual way of eating with chelicerae, small claw-like structures. Scorpions can only feed in liquid form, have external digestion. Any solid nondigestible (fur, exoskeleton, etc.) captured from pre-bristle cavity, which is expelled through the scorpion. Scorpions can consume large amounts of food in one sitting. This enables scorpions to survive long when deprived of food, some are able to survive 6 to 12 months of starvation. Scorpions differ very little, and their insoluble residues consisting mainly of nitrogen-containing compounds such as xanthine, guanine, and uric acid. Most scorpions reproduce sexually, and most species have males and females. However, some species such as Hottentotta hottentotta, caboverdensis Hottentotta, australasiae Liocheles, Tom columbianus, metuendus Tom, Tom serrulatus, stigmurus Tom, Tom Tom and trivittatus urugayensis to reproduce by parthenogenesis, develop a process in which unfertilised eggs of living embryos. Parthenogenetic reproduction begins after the last molting scorpion maturity and continues thereafter.

Sexual reproduction is accomplished by the transfer of a spermatophore of male to female, scorpions have a cut and complex mating ritual to do so. The courtship begins with understanding the male from the female with his pedipalps, the pair then "dance" as "ride à deux". This "dance", the male, the female leads in the search for a suitable place to deposit his spermatophore. When the male has identified a suitable location, he deposits the spermatophore and then the door female. Once the pairing is complete, the male and female will separate. The male generally retreat quickly, most likely to avoid being exploited by the female, although sexual cannibalism is common with scorpions. All known scorpion species possess venom and use it primarily to kill or paralyze their prey so that it can be eaten. The 1000 + known species of scorpion, only 25 have venom that is deadly to humans, most which are of the family Buthidae.

Animal You | Impala | Impala are sexually dimorphic. Are 75 and 95 cm (30 and 37 inches) high. Average mass of 40-75 kg male Impala (88-170 pounds), while women weighing 30-50 kg (66-110 lbs). Women, known as sheep without horns. It has distinctive black and white stripes on the back and tail of black impala in very few places in Africa, is a very rare form causes a recessive gene, the color black in these animals. Impala have scent glands in the skin of the hind legs and sebaceous glands fall on your head. Impala is an ecotone 'live in open forests with little undergrowth and grassland with low average height "types. Impalas are adaptable forage. Usually in the grass and change with the seasons navigation. During the dry season, browse the leaves, buds, seeds and shrubs. Leopards, cheetahs, lions and wild dogs hunting impala.

Impala, like other small sized African antelope, have a special agreement within the mandible similar steps strepsirrhine primates during comb hair to use and remove ectoparasites. Women and young form herds of up to 200 people. When food is plentiful, adult males will establish territories. Territorial males are herds around women who serve their country and travel to the singles that follow. Also deter weaned males. A male impala tries to prevent the female to leave the area. Great form, mixed tranquil herds of men and women. Young male impala over his flock had to leave in a bachelor herd of about 30 personas.La impala breeding season, also grind begins at the end of the rainy season in May. By isolating birth, a female impala herd. When frightened or anxious, the whole herd starts to jump to confuse predators. Can distances greater than 10 m (33 ft) and 3 m jump (9 feet) in the air, exploding in a beautiful impala jump.

Howler Monkey


Animal You | Howler Monkey | Howler monkeys have a short snout and nose mostly rounded. Their noses are very enthusiastic, and Howler can feel their food (especially fruits and nuts) to 2 km. Like many New World monkeys have taken code. Unlike other New World monkeys, howler monkeys males and females have trichromatic vision color. This has evolved independently from other New World monkeys due to gene duplication. Howler are dimorphic species can also be dichromatic (ie, caraya Alouatta). The howler quadruped moving in the highest branches, usually choose a branch with at least two hands or one hand and the tail at any time.

Howler monkeys mature adults often rely on the support line for the whole body, while the young do it more often. The majority of the species of howler monkeys live in groups of six to 15 animals, from one to three adult men and women different. Mantled howler monkeys are an exception, usually live in groups of 15-20 people with more than three adult males. Unlike most New World monkeys, which is a graph group sex, young people of both sexes emigrate from their natal group, so that the howler monkeys could spend most of their adult life costs, in collaboration with monkeys non-relatives.

Group size varies depending on the species and location, a man respected for men, women four girls. Each room has an enlarged hyoid bone or basihyal help their vocalizations strong. Entries consist of "crying" strong and deep and guttural grunts. Howler monkeys are widely regarded as the strongest animal on earth. Howlers eat mainly top canopy leaves of fruit, buds, flowers and nutsHowler monkeys are also known to occasionally attack birds' nests and consume eggs and poultry. While seldom aggressive, howler monkeys, do not mix well to captivity and moodiness. However, the black howler monkey (Alouatta caraya) is a relatively common monkey in contemporary Argentina, because of their gentle nature, against the aggressive tendencies of capuchin monkeys, despite their lack of intelligence, and liabilities affected by the size of their strong men droppings and sounds. Copán is particularly known for his depictions of deities howler.

Harbor Porpoise


Animal You | Harbor Porpoise | Pigs are a bit smaller than other porpoises, about 67-85 cm (26-33 inches) long at birth, 6.4 to 10 kg. Fins, dorsal fin, caudal fin and a dark gray back. Party a little easier variegated gray. Pigs English word comes from the Old French (French pourpois porpais 12 cents). What porcopiscus medieval Latin, which is a compound porcus (pork) and piscus (fish). An old word, probably a loan translation of German words, Friday marsvin mereswijn Danish and Dutch (porpoises). Classical Latin had a similar name, porculus Marina, and the idea of the name, probably imaginary nose looks like pigs or pigs breathing sound that resembles a pig snoring.

Taxonomic species RNosaepa rNosaepa name, the Greek form verlatijnste φώκαινα, phōkaina "Great Seal", as described by Aristotle, he φώκη, phōkē "printing." Pig widespread species in the cold coastal waters of the North Atlantic the North Pacific and the Black Sea. population of these regions, current and classified as a subspecies of P. separate Phocoena g in the North Atlantic and West Africa, P. relicta was in the Black Sea and the Sea of Azov, the persons named in the Pacific Northwest and P. g vomerina in the northeast Pacific. In the Atlantic port porpoises may be in a curved strip of water off the coast of West Africa to the coast of Spain, France, Great Britain, Ireland, Scandinavia, Iceland, Greenland, Nova Scotia and Newfoundland and the east coast of the United States. Pig has a total population of 700,000 people. Areas with a large number include the North Sea, where about 350,000 pigs, as well as in the Gulf of Maine / Bay of Fundy region, the West Coast and Alaska.

Porpoises prefer temperate and subarctic waters. When in deeper waters, guinea pigs can operate in water as fish pearlsides. Young pigs approximately 7% to 8% of their body weight consumed each day to survive, which is about 15 pounds or 7 kg of fish. Predators include porpoises white sharks and killer whales (orcas). Dive into 220m porpoises were reported. Porpoises of social life are not well understood. They are generally considered solitary species. Most of the time, the pig alone or in groups of five animals. Porpoises analysis. Males produce large quantities of seed, perhaps sperm competition. 10.11 months pregnant pigs usually. Porpoises were traditionally hunted for their meat and their cries, used to relieve fuel. Thousands of guinea pigs is the end of the 19th century and still clinging on a smaller scale during the world wars. In prehistoric times, this animal hunting people Alby on the east coast of the island of Öland, Sweden.

Population of harbor porpoises in the North Sea, the Baltic Sea, the Northwest Atlantic, Black Sea and North-West Africa listed in Annex II of the Convention on the Conservation of Migratory Species Wild Animals (CMS). The greatest threat to pigs are static methods of fishing, such as gill nets and Hill. Bycatch from the Black Sea, the Baltic Sea, the North Sea and the east coast of the United States and Canada. Porpoise explosion device called an acoustic transmitter designed to keep pigs from the network, and many studies have shown to be very effective in reducing the confusion. However, the question was raised about the noise pollution created to reduce ping and if their effectiveness over time with pigs that live sound.

Animal You | Groundhog | In areas with fewer natural predators and large amounts of alfalfa, groundhogs can grow to 80 cm (30 inches) and 14 kg (31 lbs). Groundhogs are well adapted for digging, with the members of the court, yet powerful curved claws and thick. Adapted to temperate habitat, groundhogs are covered with two layers of fur: a dense layer and a layer of gray streaks in her that the groundhog its distinctive appearance "frozen" indicates. In captivity, groundhogs are reported to live 14.9 years. Common predators for groundhogs, wolves, coyotes, foxes, lynxes, bears, large hawks and dogs. Marmotte young people are often at risk for predation by snakes, which easily enter the burrow. Mostly herbivorous, groundhogs primarily eat wild grasses and plants, including berries and agricultural crops when available. Groundhogs also eat worms, grasshoppers, insects, snails and other small animals, but they are omnivores like most other Sciuridae.

Hydrates marmots eat green leafy plants, instead of drinking from a fountain. Groundhogs are excellent burrowers, using burrows for sleeping, rearing young, and hibernating. The average groundhog has been estimated at about 1 m3 (35 cubic feet) or 320 kg (710 pounds) of the moving soil by digging a hole. Though groundhogs are the most solitary of the marmots, several people occupy the same burrow. Groundhog burrows usually 2-5 tickets, providing groundhogs principal means to escape predators. Groundhogs are one of the few species that enter into true hibernation, and often a "winter burrow" just build for this purpose. Woodchucks are primarily daytime.

Despite its large size, the marmots are expert swimmers and tree climbers or escape predators excellent if you want to explore your surroundings. Groundhogs may squeal when fighting, can seriously wounded by an enemy or other sounds marmots are low and a barking sound produced by grinding your teeth when marmots are afraid, the hair of the tail of the state, giving the appearance a tail hair brush. The breeding season runs from early March to mid or late April, after hibernation. The waste is produced annually, usually by 5:58 blind and helpless young bald. Young groundhogs are weaned and ready for their own burrows least five to six weeks old to search. The groundhog prefers open country and forest edges, and rarely far from a burrow entrance. Groundhogs are often hunted for sport, which tends to control their numbers.  This Marmot an animal known to many people in the United States and Canada. Groundhogs raised in captivity can be socialized relatively easily, but their aggressive nature can pose problems.

United States and Canada, the annual Groundhog Day Groundhog given recognition and popularity, and the film of the same name. Most of them are popularly known groundhogs Wiarton Willie and Punxsutawney Phil, well maintained low Groundhog Day festivities in Wiarton, Ontario and Punxsutawney, Pennsylvania, respectively. A famous southern groundhog, General Beauregard Lee, is based on the Yellow River Game Ranch outside Atlanta, Georgia.If infected with woodchuck hepatitis B, are 100% risk of developing liver cancer, making them a good model for testing treatments for hepatitis B and liver cancer. Although archaeologists have never dug Ufferman site, there are many objects found thanks to the activities of the local groundhogs.

Gray Whale


Animal You | Gray Whale | The gray whale is traditionally defined as the only living beings in its genus and family. Recent DNA analysis shows some family Balaenopteridae Razorbacks as the humpback whale, Megaptera novaeangliae, and fin whales, Balaenoptera physalus stronger in gray whales whales as some others, such as minke whales are related. The common name of the whale comes from the color. The now extinct subfossil gray whales along the Atlantic coast of England and Sweden remains gray is used for the first scientific description of a kind only in Pacific waters to survive. Many other names are assigned to the gray whale, including desert whale, monkfish, gray back, mussel digger and pull the thread. The gray whale is a slate gray and dark was covered with gray-white patterns, scars caused by parasites that are cold in their diet. Individual whales are usually identified with photos of their dorsal surface and connected to scars and blemishes match parasites from cases of the whale, or even apply.

Measure the gray whale, 16 feet (4.9 m) in length for newborns 43-50 feet (women tend to be slightly larger than males) (13-15 m) for adults. Newborns are dark gray to black. An adult gray whale can be up to 40 tonnes (39 tons long, 44 short tons)., With a typical range of 15-33 tons (15-32 tonnes in length, 17 to 36 short tons) The gray whale also lacks a dorsal fin, instead of tilting 6-12 dorsal ("Together") which projections on the middle line of the back, the worms. Both male and female whales puberty around the age of eight. Women show strong play synchronized estrus in late November and early December. This unique event ovulation is of the opinion that the annual migration of the species agree that births in warmer waters. Men also show seasonal changes, that an increase in testicular mass suffering heat eventually women correlates. The gestation period of gray whales is 13.5 months. The calf is born tail first and measures about 4 meters (13 feet) long. The waters of the shallow lagoon where gray whales breed is believed to be the newborn sharks and orcas to protect.

Usually, animals in northern waters during the summer driving and opportunistic feeding during migration, depending primarily on its extensive fat reserves. Gray whale calf drinking 50-80 liters (190 to 300 liters) of milk from their mothers 53% fat per day. The main food habitat of the western Pacific subpopulation is. Some gray whales were also seen in western Kamchatka, but so far all whales photographed, known Piltun area. Every year in October, as the northern ice pushed south and small groups of gray whales in the eastern Pacific that begin with a two or three months, 8000-11000 km south-career (5000-6800 miles). Western gray whales summer in the Sea of Okhotsk, in particular, on the northeastern coast of Sakhalin Island (Russia). Day and night, the average gray whale about 120 kilometers (75 miles) per day, with an average speed of 8 kilometers per hour (5 mph). The whale watching industry provides ecotourists and marine mammal enthusiasts the ability to create groups of gray whales that migrate see.

In late December and early January in the eastern gray start to the lagoons of Baja delivery to reach. The three most popular lakes Scammon Lagoon (formerly known in English as Scammon Lagoon after whaleman Charles Melville Scammon those holes discovered in the 1850s and drove the gray shades), San Ignacio and Magdalena.  These whales are the first women, mostly pregnant women who want to protect the lagoons to bear their calves, along with single women looking for couples. Mid-February to mid-March, the majority of the population lived in ponds, gray whales with lactation, parturition and mating. In February and March, the first from the lagoons are men and women without children. A population of about 200 gray whales stay along the eastern Pacific coast from Canada to California in the summer, not to trip over the waters of Alaska to make. This summer resident group is known as the Pacific Coast Food Group. Gray whales were safe from commercial whaling by the International Whaling Commission (IWC), published since 1949, and is no longer widely hunting.

Limited hunting of gray whales since, but especially in the Chukotka region in northeastern Russia, where a large number of gray whales spend the summer months. This yacht was under a 'traditional subsistence whaling / "may be exempted from the ban on commercial whaling. Currently, the annual quota for whaling in the gray area of 140 per year. Killed except a gray whale in 1999, the Makah people hunting prevented by a series of legal challenges. Since 2008, the IUCN is the gray whale as "least concern" from the viewpoint of protection. The CBI Bowheads subcommittee, Right and Gray in 2011 to preserve endangered western gray whale is large due to the small size of the population and the potential impact of human activities. In breeding grounds in Baja California, Mexican law protects whales in the lagoons, and thus makes it possible whale watching. Gray whales belong to the Canadian Species at Risk Act, the Canadian government consider preparing management plans for whales and necessary for the development interests of protected whales.

Migrating gray whales off the Pacific coast was observed for the first time since Marineland of the Pacific in Palos Verdes, California. The gray whale census has recorded an immigration official gray whale census data on population migration of Pacific gray whale is keeping the Pacific gray whale in 1985. This census is the largest census operation Pacific gray whales.
