All About Animal

Gray wolf

The gray wolf (Canis lupus) is a species of canid native to the wilderness and remote areas of North America, Eurasia, and North Africa. It is the largest member of its family, with males averaging 95–100 lbs, and females 80–85 lbs. It is similar in general appearance and proportions to a German shepherd, or sled dog, but has a larger head, narrower chest, longer legs, straighter tail and bigger paws. Its winter fur is long and bushy, and is usually mottled gray in color, though it can range from nearly pure white, red, or brown to black.

The species originated during the middle Pleistocene period, probably in the Indian subcontinent. Within the genus Canis, the gray wolf represents a more specialised and progressive form than its smaller cousins (the coyote and golden jackal), as demonstrated by its morphological adaptations to hunting large prey, its more gregarious nature  and its highly advanced expressive behavior.  It is a social animal, travelling in nuclear families consisting of a mated pair, accompanied by the pair's adult offspring..

The gray wolf is typically an apex predator throughout its range, with only humans and tigers  posing a serious threat to it. It feeds primarily on large ungulates, though it will also eat smaller animals, livestock, carrion, and garbage.

The gray wolf is one of the world's most well researched animals, with probably more books written about it than any other wildlife species.  It has a long history of association with humans, having been despised and persecuted in most agricultural communities due to its attacks on livestock, while conversely being respected by some Native American tribes. It is the sole ancestor of the dog, which was first domesticated in the Middle East. Although the fear of wolves is prevalent in many human societies, the majority of recorded attacks on people have been attributed to animals suffering from rabies. Non-rabid wolves have attacked and killed people, mainly children, but this is unusual, as humans are not part of the wolf's natural prey.^] Deliberate human persecution has reduced the species' range to about one third, though its still relatively widespread range and stable population means that the species is not threatened at a global level, and is therefore classified by the IUCN as Least Concern.

Hamster 

Hamster is a herbivore animal.Sometimes, hamster is seen us mouse.Some people like this animal.Hamster Old World rodent,related to the voles,lemmings, and New World Mice.They are many hamster species classified in several genera.All are nocturnal animals,solitary,with chunky bodies,some moustache,has two small eyes,a short tail,two small ears,thick fur,soft and so on.The colour hamster are very multifarious manner as white,brown,golden brown,and etc.Hamster behavior varies depending on the environment,genetics,intraction with people.Hamster are often used as laboratory animals in more economically.Hamster can also as animal pet,because it cute and funny.

Some of the larger species have scent glands on the flanks; the scent is used for territorial marking. Hamsters feed on grain and other plant matter and are serious agricultural pests in many parts of their range. The common, or European, hamster, Cricetus cricetus, of the temperate parts of Europe and W Asia, is reddish brown with black underparts and white patches on the nose, cheeks, throat and flanks. It is about 12 in. (30 cm) long, with a very short tail. It stores grain in its chambered burrow for use in winter during interruptions of hibernation.

The Syrian, or golden, hamster, Mesocricetus auratus, of E Europe and W Asia, is familiar as a laboratory animal and pet, but is little known in the wild state; all of the domestic stock is descended from a single group captured in 1930. About 6 in. (15 cm) long, it is lighter colored than the common hamster, with white underparts. Rat-tailed, or Eurasian, hamsters (C. cricetulus) are widely distributed through Europe and Asia; these somewhat longer-tailed forms are quite fierce, preying on other rodents as well as on lizards and small birds, although their diet is mostly vegetarian. Other hamsters are found in Europe and Asia, and species of the hamster genus Mystromys, called white-tailed rats, are found in Africa. Hamsters are classified in the phylum Chordata, subphylum Vertebrata, class Mammalia, order Rodentia, family Cricetidae.

 

Lion

The lion (Panthera leo) is one of the four big cats in the genus Panthera and a member of the family Felidae. With some males exceeding 250 kg (550 lb) in weight,^[4] it is the second-largest living cat after the tiger. Wild lions currently exist in sub-Saharan Africa and in Asia, with an endangered remnant population in Gir Forest National Park in India, having disappeared from North Africa and Southwest Asia in historic times. Until the late Pleistocene, about 10,000 years ago, the lion was the most widespread large land mammal after humans. They were found in most of Africa, across Eurasia from western Europe to India, and in the Americas from the Yukon to Peru.^[5] The lion is a vulnerable species, having seen a major population decline of 30–50% over the past two decades^{[date missing]} in its African range.^[2] Lion populations are untenable outside designated reserves and national parks.

Although the cause of the decline is not fully understood, habitat loss and conflicts with humans are currently the greatest causes of concern. Within Africa, the West African lion population is particularly endangered.

Lions live for 10–14 years in the wild, while in captivity they can live longer than 20 years. In the wild, males seldom live longer than 10 years, as injuries sustained from continual fighting with rival males greatly reduce their longevity.^[6] They typically inhabit savanna and grassland, although they may take to bush and forest. Lions are unusually social compared to other cats. A pride of lions consists of related females and offspring and a small number of adult males. Groups of female lions typically hunt together, preying mostly on large ungulates. Lions are apex and keystone predators, although they scavenge as opportunity allows. While lions do not typically hunt humans, some have been known to do so. Sleeping mainly during the day, lions are primarily nocturnal, although bordering on crepuscular^[7][8] in nature.
Highly distinctive, the male lion is easily recognised by its mane, and its face is one of the most widely recognised animal symbols in human culture. Depictions have existed from the Upper Paleolithic period, with carvings and paintings from the Lascaux and Chauvet Caves, through virtually all ancient and medieval cultures where they once occurred. It has been extensively depicted in sculptures, in paintings, on national flags, and in contemporary films and literature. Lions have been kept in menageries since the time of the Roman Empire, and have been a key species sought for exhibition in zoos over the world since the late 18th century. Zoos are cooperating worldwide in breeding programs for the endangered Asiatic subspecies.
