The tiger

0

The Via tiger (Panthera tigris) is the largest cat species and belongs to the genus Panthera. It is most recognizable for the dark vertical stripes under the light on the orange-brown fur. It is a top predator, primarily preying on unsuspecting animals such as deer and wild boar. It is a terrestrial and generally isolated but social predator that needs large habitats and supports its needs for raising victims and children. The tiger cubs stay with the mother for about two years before becoming independent and establish their home from the mother’s home.

The tiger once stretched from the region of western Anatolia to the Amur River Basin, and from the foothills of the Himalayas in the south to Bali in the Sunda Islands. The Tigers have lost at least 93% of their population since the early 20th century and have been wiped out in western and central Asia, the islands of Java and Bali, and large areas of Southeast and South Asia and China. Today, the Via tiger range extends from the temperate forests of Siberia to the tropical and subtropical forests of the Indian subcontinent and Sumatra.


The tiger is endangered on the IUCN Red List. As of 2015, the global wild tiger population is estimated to be between 3,062 and 3,948, with the majority of the population living in small pockets isolated from each other. India currently has the largest tiger population. Habitat destruction, habitat fragmentation, and poaching are the main causes of population decline. Tigers are vulnerable to human-wildlife conflict, especially in countries with high human populations.

Leopard is one of the most recognizable and popular megaphones in the world. It has been a prominent feature of ancient myths and legends and continues to be portrayed in modern films and literature and appears as a mask for many flags, armor, and sporting groups. The tiger is the national animal of India, Bangladesh, Malaysia and South Korea.

Middle English Tigers and Old English Tigers are derived from the Old French Tigers and the Latin Tigers. This is a borrowing of the classic Greek ig 'Tigris'. It is a foreign loan of unknown origin, meaning 'Tiger' as well as the Tigris River. Its origin may be in the Persian word tigra meaning 'pointed or sharp' and the word Avestan may be tiggari 'arrow', perhaps referring to the leaping speed of the tiger, although these words have no known meaning.

The common name Panthera is derived from the Latin word Panthera and the ancient Greek word 'panther'. The Sanskrit word णा्र pāṇḍ-ara means 'pale yellow, white, white'

The tiger's closest relatives were previously thought to be the Panthera species of lion, leopard, and jaguar. The results of the genetic analysis show that about 2.88 million years ago, the offspring of tigers and snow leopards evolved from other Panthera species, both of which may be more closely related than lions, leopards, and jaguars. Geographical origin Panthera is most likely North Central Asia or the Holar Arctic region. The tiger-snow leopard lineage dispersed during the Miocene in Southeast Asia.


The Panthera zdanskyi is considered a brother taxi of the modern tiger. It lived about two million years ago at the beginning of the Pleistocene, and its fossil ruins were excavated in northwestern China's Gansu Province. It was smaller and more "primitive" but functionally and environmentally similar to the modern tiger. It is debatable whether there is a striped pattern. Northwest China is considered to be the origin of the Tiger dynasty. During the early Pleistocene, tigers thrived in response to adaptive radiation from predatory species such as deer and bovine in Southeast Asia.

Panthera tigris trinilensis lived about 1.2 million years ago and is known from fossils excavated near the trail in Java. During the prehistoric era, the Tigers of Wanjiang, Engandong, Trinil and Japan became extinct. The Tigers reached eastern Beringia, Japan, and Sakhalin in late Pleistocene to India and North Asia. Some fossil skulls are morphologically different from lion skulls, which may indicate the presence of tigers in Alaska about 100,000 years ago.


Two published phalanx bones were found in the middle of a collection of other animal bones and stone tools in the Ile Cave near the village of New Ibaje, on the Philippine island of Palawan. They were smaller than the fossils of the mainland Tigers. Otherwise, the original humans appear to have collected the bones,  so it appears that the tiger parts were imported elsewhere, or that the leopard was colonized from Borneo to the Holocene, considering the proximity of the two islands. Tiger fossils were also excavated in Sri Lanka, China, Japan and Sarawak (Malaysia) during the Pliocene, Pleistocene and early Holocene. Prehistoric or extinct in recent times.


Preliminary results of a physical study show that all living tigers had a common ancestor 72,000-108,000 years ago. The possible tiger range between the Pleistocene and the Holocene was predicted to combine with bio-climatic data to create ecosystem models based on more than 500 local records of tigers. As its prototype, the last glacier shows the maximum contradictory Tiger range, showing the genetic flow between the Tiger populations in the mainland of Asia. The Caspian Tiger population may be connected to the Bengal Tiger population through a corridor less than 4,000 m (13,000 ft) in the Hindu Kush. The Tiger population in the Sunda Islands and the mainland of Asia may have been segregated during the inter-global eras.

The complete genetic sequence of the tiger was published in 2013. It was found that it has a repetitive composition similar to that of other cats and has significantly preserved synthesis.

Details

The tiger has a muscular body, a large forehead, a large head, and a tail about half the length of its body. It is peculiar and weighty and varies in color from white to orange and brown and with distinct vertical black stripes that are unique to each individual. Stripes are advantageous for hiding in vegetation such as strong vertical patterns light and long grass with shade. The tiger is one of several species of striped cats. It is not known why it is the most common hidden pattern between spotted patterns and rosette petals. The orange color also helps to hide as the tiger’s prey is dichromate. The coat pattern of a tiger can still be seen when shaving. This is not because of the pigmentation of the skin, but because of the straw and hair that are embedded in the skin, similar to human beards (five shades of skin in the evening) and are similar to other large cats. Fur and jaws around the neck and long-bearded trees, especially males. Students are round with yellow irises. The small, rounded ears have a white spot on the back, surrounded by black.

The skull of a leopard resembles that of a lion, and the anterior region is generally less depressed or flattened and has a slightly longer posterior region. The lion's skull shows wide nasal openings. The structure of the lower jaws is a reliable indicator of their identification due to the variation in the skull size of the two species. The tiger has somewhat strong teeth; Its slightly curved dogs have the longest mm between live petals. Crown height up to 90 (3.5 inches).

Size

There is a significant sex duplication between male and female bodybuilders, with the latter being constantly smaller. In large tiger subspecies, the difference in size between them is proportionally greater, with males weighing 1.7 times more than females. Men also have wide forehead pads that allow sex to be detected on the track. It has been hypothesized that the body size of different tiger populations may be correlated with climate and may be explained by thermoregulation and Bergman's law or by the distribution and size of existing species.


On average, males vary in total length from 250 to 390 centimeters (8.2 to 12.8 feet) and weigh between 90 and 300 kilograms (200 to 660 pounds). 316 to 383 (12.4 to 15.1 inches). The total length of females varies from 200 cm to 275 cm (6.56 ft to 9.02 ft) and weighs 65 to 167 kg (143 to 368 lb). 268 to 318 (0.879 to 1.043 feet). The tail length of both males and females is 0.6 to 1.1 m (24 to 43 inches). Bengal and Siberian tigers are also among the tallest cats with shoulder height. They are also ranked among the largest cats weighing more than 300 kg (660 lb). The tigers in the Sunda Islands are smaller and lighter than the tigers in Asia, rarely weighing more than 142 kilograms (313 lb).


Color changes

There are three color variants: white, gold, and striped snow white. Now the wild tiger population is declining and is rarely seen in the wild. The white tiger has white fur and sepia brown stripes. The golden tiger has a pale golden hue with dark brown and reddish-brown stripes. The snow-white leopard has a tail with extremely faint stripes and pale reddish-brown rings. Both snow white and golden tigers are homogeneous for corneal genetic mutations. The black tiger is a color variant due to pseudo melanism. The thick stripes between them are close to each other so that the background color is not visible between the stripes.

The white tiger has no pheomelanin (creates orange) and has dark sepia-brown stripes and blue eyes. This altered pigment is caused by a mutated gene that is inherited as an autoimmune depression and is determined by a white locust. It is not an albino as it does not have much effect on black pigment. The mutation modifies the single amino acid in the transport protein SLC45A2. Both parents must have alleles to produce white pups. In the early and mid-20th century, white tigers were recorded and shot in Odisha, Bihar, Assam, and Rewa in central India. The local Maharaja began breeding tigers in the early 1950s, keeping a white male tiger with its normal-colored daughter. They had white pups. In order to preserve this depressive trait, only a few whites were used for breeding in captivity, resulting in high levels of breeding. Strabismus, childbirth, malformations, and premature death are the leading causes of many health problems among white people in captivity. Other physical ailments include cleft palate and scoliosis.


The Tigers' life plan condemns the breeding of white tigers, accusing them of having mixed ancestors and an unknown generation. The genes responsible for whiteness represent 0.001% of the population. The unequal growth of white tigers indicates breeding among homogenous depressed individuals. This leads to infectious depression and loss of genetic variability
