Latest Cats Animal Wallpapers For Desktop

The cat (Felis catus), also known as the domestic cat or housecat to distinguish it from other felines and felids, is a small furry domesticated carnivorous mammal that is valued by humans for its companionship and for its ability to hunt vermin and household pests. Cats have been associated with humans for at least 9,500 years, and are currently the most popular pet in the world. Owing to their close association with humans, cats are now found almost everywhere on earth.

Cats are similar in anatomy to the other felids, with strong, flexible bodies, quick reflexes, sharp retractable claws, and teeth adapted to killing small prey. As nocturnal predators, cats use their acute hearing and ability to see in near darkness to locate prey. Not only can cats hear sounds too faint for human ears, they can also hear sounds higher in frequency than humans can perceive. This is because the usual prey of cats (particularly rodents such as mice) make high frequency noises, so the hearing of the cat has evolved to pinpoint these faint high-pitched sounds. Cats rely more on smell than taste, and have a much better sense of smell than humans.

Despite being solitary hunters, cats are a social species and use a variety of vocalizations, pheromones and types of body language for communication. These include meowing, purring, trilling, hissing, growling, and grunting.

Cats have a rapid breeding rate. Under controlled breeding, they can be bred and shown as registered pedigree pets, a hobby known as cat fancy. Failure to control the breeding of pet cats by spaying and neutering and the abandonment of former household pets has resulted in large numbers of feral cats worldwide, with a population of up to 60 million of these animals in the United States alone.

As The New York Times wrote in 2007, "Until recently the cat was commonly believed to have been domesticated in ancient Egypt, where it was a cult animal", but a study that year revealed that the lines of descent of all house cats probably run through as few as five self-domesticating African Wildcats (Felis silvestris lybica) c. 8000 BC, in the Near East. The earliest direct evidence of cat domestication is a kitten that was buried alongside a human 9,500 years ago in Cyprus.










Camel Animal Wallpapers

A camel is an even-toed ungulate within the genus Camelus, bearing distinctive fatty deposits, known as humps, on its back. There are two species of camels: the dromedary or Arabian camel has a single hump, and the Bactrian camel has two humps. Dromedaries are native to the dry desert areas of West Asia, and Bactrian camels are native to Central and East Asia. Both species are domesticated; they provide milk and meat, and are beasts of burden. Camels are equipped to deal with harsh desert conditions, such as flying sand. The camel's eyes are protected by long eyelashes and have an extra thin eyelid. It can see through this 3rd eyelid allowing them to find there way even in a harsh desert storm.

The term camel, (from the Arabic ???, gml, derived from the triconsonantal root signifying "beauty"), is also used more broadly to describe any of the six camel-like creatures in the family Camelidae: the two true camels, and the four South American camelids: the llama, alpaca, guanaco, and vicuña.

The average life expectancy of a camel is 40 to 50 years. A fully grown adult camel stands 1.85 m (6 ft 1 in) at the shoulder and 2.15 m (7 ft 1 in) at the hump. The hump rises about 30 in (76.20 cm) out of its body. Camels can run at up to 65 km/h (40 mph) in short bursts and sustain speeds of up to 40 km/h (25 mph).

Fossil evidence indicates that the ancestors of modern camels evolved in North America during the Palaeogene period (see also Camelops), and later spread to most parts of Asia. The people of ancient Somalia or the Kingdom of Punt first domesticated camels well before 2000 BC.

A butterfly is a mainly day-flying insect of the order Lepidoptera, the butterflies and moths. Like other holometabolous insects, the butterfly's life cycle consists of four parts, egg, larva, pupa and adult. Most species are diurnal. Butterflies have large, often brightly coloured wings, and conspicuous, fluttering flight. Butterflies comprise the true butterflies (superfamily Papilionoidea), the skippers (superfamily Hesperioidea) and the moth-butterflies (superfamily Hedyloidea). All the many other families within the Lepidoptera are referred to as moths.

Butterflies exhibit polymorphism, mimicry and aposematism. Some, like the Monarch, will migrate over long distances. Some butterflies have evolved symbiotic and parasitic relationships with social insects such as ants. Some species are pests because in their larval stages they can damage domestic crops or trees; however, some species are agents of pollination of some plants, and caterpillars of a few butterflies (e.g., Harvesters) eat harmful insects. Culturally, butterflies are a popular motif in the visual and literary arts.










Latest Buffalo Animal Wallpapers Download For Free

The water buffalo or domestic Asian water buffalo (Bubalus bubalis) is a large bovine animal, frequently used as livestock in southern Asia, and also widely in South America, southern Europe, north Africa, and elsewhere.

In 2000, the United Nations Food and Agriculture Organization estimated that there were approximately 158 million water buffalo in the world, and that 97% of them (approximately 153 million animals) were in Asia. There are established feral populations in northern Australia, but the dwindling true wild populations are thought to survive in India, Bangladesh, Pakistan, Nepal, Bhutan, and Thailand. All the domestic varieties and breeds descend from one common ancestor, the wild water buffalo, which is now an endangered species. The domestic water buffalo, although derived from the wild water buffalo, is the product of thousands of years of selective breeding in either South Asia or Southeast Asia.

Buffalo are used as draft, meat, and dairy animals. Their dung is used as a fertilizer and as a fuel when dried. In Chonburi, Thailand, Pakistan and in southwestern region of Karnataka, India, there are annual water buffalo races known as Kambala. A few have also found use as pack animals carrying loads even for special forces.[citation needed]

American bison are known as buffalo in parts of North America, but not normally in other usages; bison are more closely related to cattle, gaur, banteng, and yaks than to Asian buffalo. The water buffalo genus includes water buffalo, tamaraw and anoas—all Asian species. The ancestry of the African buffalo is unclear, but it is not believed to be closely related to the water buffalo.

Members of the genus Bison are large even-toed ungulates within the subfamily Bovinae. Two extant and four extinct species are recognized. The surviving species are the American bison, also known as the American buffalo (although it is not related to the true buffalo), Bison bison (with two subspecies, the plains bison, Bison bison bison, and the wood bison, Bison bison athabascae), found in North America, and the European bison, or wisent (Bison bonasus), found in Europe and the Caucasus. While these species are usually grouped into their own genus, they are sometimes included in the closely related genus Bos, together with cattle, gaur, kouprey and yaks, with which bison have a limited ability to interbreed.
