What's so special about tigers

What is so special about tigers? As the largest member of the tiger family, the tiger is powerful and one of the most worried carnivores in nature. Their beautiful orange and black striped coats can provide camouflage when hunting at night. What is so special about tigers?

What is so special about tigers? 1 A tiger is strong, with developed forelimbs, a big head and a tail about half the length of its body. Its fur is thick and thick, and its color varies between orange and brown. There is a white area in its abdomen, and each individual has a unique vertical black stripe, which is conducive to camouflage in vegetation. Tiger is one of the few striped cats. When the tiger is shaved, its fur pattern is still visible, which is not due to skin pigmentation, but because hair follicles are embedded in the skin. Their necks and chins have mane-thick hair and long beards, especially in males. Pupils are round and irises are yellow. There is a prominent white spot on the back of the small round ear, which is surrounded by black. These points are considered to play an important role in intraspecific communication.

The skull of a tiger is similar to that of a lion. The forehead area is usually not too concave or flat, while the occipital area is slightly longer. The lion's skull shows a larger nostril. Because the skulls of these two species are different in size, the structure of mandible is a reliable indicator to distinguish them. Tiger's teeth are quite strong, and some curved canine teeth are the longest in the existing cats.

There are obvious sexual dimorphism between men and women, and women are always smaller than men. Among large tigers, the difference between male and female is greater, and the weight of male is 1.7 times that of female. The paw pads of males are also wider than those of females, which makes it possible to judge the sex by footprints. It is speculated that the size of different tiger populations may be related to the climate, which can be explained by thermoregulation and Bergman's law (the size of the same warm-blooded animal will increase with the increase of latitude or altitude in the living area), or by the distribution and size of existing prey.

Generally speaking, men are 2.5-3.9 meters long, 90-306 kilograms in weight and 3 16-383 millimeters in skull length. The female is 2.0-2.75 meters long, weighs about 65- 167 kg, and the length of the skull is between 268-318 mm. No matter which sex, the length of the tail is 0.6- 1. 1 meter. Bengal tiger and Siberian tiger are the cats with the highest shoulder height, and they are also listed as the largest cats in history. Tigers in sunda islands (a series of islands in the southwest of Malay Archipelago) are smaller and lighter than those in mainland Asia, rarely exceeding 142kg.

The large male Siberian tiger (Siberian tiger) is more than 3.5 meters long and weighs at least 300 kilograms. This is much heavier than 75- 140 kg of Sumatra tiger. On the shoulders, the tiger's height may be between 0.7- 1.22 meters. The total length of Bengal tiger male from nose to tail root is 2.7-3. 1m, the weight is 180-258kg, the female is 2.40-2.65m, and the weight is 100- 160kg. In northern India and Nepal, the average weight is higher, reaching 235kg for men and 140kg for women. The weight records of wild individuals show that they are heavier than wild Siberian tigers.

Siberian tiger

It is reported that the world's largest wild tiger is 3.38 meters long. The heaviest tiger in captivity is the Northeast Tiger, weighing 465 kilograms. According to records, the heaviest wild tiger is a Bengal tiger from northern India, which was photographed at 1967. It is said that it weighed 388.7 kilograms, but it had a big meal before it was killed. Without this big meal, its weight will be significantly reduced.

Varieties of different colors

White tigers lack yellow pigment, with dark brown stripes and blue eyes. This change in pigmentation is caused by a mutant gene, which is an autosomal recessive inheritance. It's not albinism, because the black part is hardly affected. From the early to the middle of the 20th century, white tigers were recorded in Orissa, Bihar, Assam and Madhya Pradesh in Reva. The local Indian maharaja began to raise tigers in the early 1950s, and together with his normal-skinned daughter, he raised a white male tiger. They have white cubs. In order to maintain this recessive trait, only a small number of white individuals are used in captive breeding, resulting in a high proportion of inbreeding. Inbreeding degeneration is the main cause of health problems of captive white tigers. White tiger has many problems such as strabismus, stillbirth, deformity and premature death. Other physical defects include cleft palate and scoliosis.

The real albino tiger does exist and can be called "Snow White" tiger. In this color change, the stripes are weak, while the tail has a reddish-brown ring.

Hu Jin is a variant of another color, with light golden fur and gold and reddish-brown stripes. These types are rarely recorded in the wild.

What is so special about tigers? 2 Ten characteristics and functions of tigers.

1. The tiger's hind legs are longer than its front legs. Tigers have more than 100 stripes. Just like fingerprints, no two tigers have the same pattern. Tiger's dog is about 4 inches (10 cm) long, which is about the size of a human finger. From the forest, you can hear the roar of tigers 2 miles (3 kilometers) away.

Tigers are called super carnivores, which means they only eat meat. Tigers eat cows, birds, monkeys, lizards, crocodiles and even elephants. Their digestive system can't digest fruits, plants or insects at all.

Throughout the world, tigers have always been a symbol of strength and fighting spirit. The earliest tiger fossils were two million years ago. A tiger spends about 18 hours sleeping every day. An adult tiger can jump 9 yards (8 meters) and 5 yards (5 meters) vertically.

Except for polar bears, tigers have the largest brains of all carnivores. According to ancient beliefs, tiger's body parts have magical power to treat diseases. It is said that tiger bones cure weakness; Beard is used to treat toothache; Tiger tails are used to treat skin diseases, and these long-standing beliefs have led to catastrophic tiger poaching.

Because of its huge size, tigers can starve to death in two to three weeks. A hundred years ago, tigers had eight different subspecies. Today, three of these subspecies are extinct, others are on the verge of extinction, and may disappear from the earth forever.

6. Tigers in Bali were deliberately hunted in Bali because they were considered evil. Tiger's night vision ability is six times that of human. Tiger saliva is a preservative, which is very useful for cleaning their wounds. A tiger can eat nearly1/5 in one meal-about 88 pounds (40 kilograms) of its weight. In a year, adult male tigers can eat up to 8000 pounds of meat.

7. Modern tigers did not evolve from prehistoric saber-toothed tigers. In fact, they are not closely related. South China tiger has the least stripes and Sumatra tiger has the most stripes. Northeast tiger has fewer stripes than Bengal tiger, and the stripes are brown, not black.

Unlike lions, they are prey that will fight to the death. Tigers often share food and take turns eating. Every tiger has its own smell, because they have personalized smell glands. Tigers' claws can grow to 4.7 inches (12 cm), and they kill more people than lions or leopards. Tigers may have killed hundreds of thousands of people in the19th century.

On the black market, a dead adult tiger can fetch more than 1 ten thousand dollars. In the past 100 years, more than 95% tigers have disappeared, and now there are only 5000 tigers left in the world. Their numbers are still decreasing due to poaching and habitat loss.

Tigers can run at a speed of 35 miles per hour, but they can only run a short distance. Most of their prey can outrun them, especially deer and antelope. A captive tiger can live for 20 years, and the life span of a wild tiger is between 10 and 15 years.

What is so special about tigers? 3. The predatory characteristics of tigers.

Tiger is a feline, belonging to Leopard subfamily. It is one of the five kinds of leopards. The other four are lion, leopard, jaguar and snow leopard.

Tigers mainly feed on large and medium-sized mammals, especially ungulates weighing 60-250 kg. There are many kinds of prey, including black deer (a big deer in Southeast Asia), northeast red deer, swamp deer, dolphin deer, white deer (produced in India) and wild boar. Especially black deer, wild boar, elk and swamp deer are the most popular species. It is reported that when hunting black deer (in India, black deer accounts for 60% of tiger prey), tigers will imitate the estrus calls of male black deer to attract them. Tigers can kill larger prey, such as Indian black cattle, but they will also wait for opportunities to eat smaller prey, such as monkeys, peacocks and other land birds, rabbits, porcupines and fish. They also prey on other carnivores, including dogs, leopards, pythons, Indian lazy bears and crocodiles. Although tigers are almost all carnivores, they occasionally eat some plants as dietary fiber, such as pomegranate and pistil fruit.

In Siberia, tigers prey on sika deer, moose, roe deer and musk deer in addition to elk and wild boar, which account for almost 80% of their prey. Asian black bears and Ussuri brown bears may also be the prey of tigers. According to the local conditions and the number of bears, they account for 40.7% of the hunting of Siberian tigers. In Sumatra (an island in western Indonesia), the prey includes black deer, muntjac, wild boar and Malay tapir.

Tigers generally don't prey on adult Asian elephants and Indian rhinos, but there are reports that they will kill more vulnerable cubs. However, adult rhinos occasionally become victims of tigers. When tigers are near human settlements, they sometimes prey on domestic animals, such as cattle, horses and donkeys. Old or injured tigers will become cannibals if they can't catch wild prey. This happens all over India. However, healthy tigers will attack humans. In sundarbans, healthy tigers prey on fishermen and villagers, and nearby humans make up a small part of the tiger's diet.

Tigers are thought to be mainly carnivores at night, but they also hunt in areas where humans do not exist during the day. They usually hunt alone like most other cats, ambush their prey, use their size and strength to make it out of balance, pounce on it almost at the same time, knock it down, and then bite its throat or neck with their teeth, thus successfully hunting. Despite its huge size, the speed of the tiger can reach 49-65 kilometers per hour, but it can only last for a short time. Therefore, the tiger must get close to its prey before jumping out of its hiding place. If the prey discovers the tiger's tracking before this, the tiger will usually give up hunting instead of chasing the prey or fighting it head-on. The tiger's horizontal jump can reach 10 meter, while the ordinary jump is only half the distance.

When hunting larger animals, tigers prefer to bite their throats, grab their prey with their powerful forelimbs and throw it to the ground at the same time. The tiger gripped its prey's neck until its target was strangled. In this way, a ton of Indian bison and buffalo were killed by tigers weighing about one-sixth of them. Although tigers can kill healthy adult cattle, they usually choose calves or sickly people. This healthy adult prey is difficult to deal with, because long and strong horns, legs and fangs are potentially fatal threats to tigers. Apart from tigers, no other existing land predators often prey on such large prey alone.

For smaller prey, such as monkeys and rabbits, tigers will bite the back of the neck, usually biting off the spinal cord, piercing the trachea, or cutting off the jugular vein or common carotid artery. Although it is rarely observed, there are records that some tigers attack their prey with their claws, thus killing their prey. Their claws are strong enough to break the skulls of domestic animals and break the backs of tree lazy bears. The glory of the king open hanging software

After a tiger kills its prey, it sometimes drags its prey into the vegetation. Usually, it grabs the bitten part with its mouth to drag its prey. This also requires a lot of physical strength. Once, after a tiger killed an adult bison, it dragged its huge body a distance of 12 meters. Later, when 13 men tried to drag the buffalo carcass at the same time, they couldn't move. An adult tiger can eat nothing for two weeks and then eat 34 kilograms of meat at a time. In captivity, adult tigers eat 3 to 6 kilograms of meat every day.
