The basic mammalian body type is quadruped, and most mammals use their four extremities for terrestrial locomotion; but in some, the extremities are adapted for life at sea, in the air, in trees, underground, or on two legs. Mammals range in size from the 30–40 mm (1.2–1.6 in) bumblebee bat to the 30 m (98 ft) blue whale—possibly the largest animal to have ever lived. Maximum lifespan varies from two years for the shrew to 211 years for the bowhead whale. All modern mammals give birth to live young, except the five species of monotremes, which are egg-laying mammals. The most species-rich group of mammals, the infraclass called placentals, have a placenta, which enables the feeding of the fetus during gestation.
Domestication of many types of mammals by humans played a major role in the Neolithic Revolution, and resulted in farming replacing hunting and gathering as the primary source of food for humans. This led to a major restructuring of human societies from nomadic to sedentary, with more co-operation among larger and larger groups, and ultimately the development of the first civilizations. Domesticated mammals provided, and continue to provide, power for transport and agriculture, as well as food (meat and dairy products), fur, and leather. Mammals are also hunted and raced for sport, kept as pets and working animals of various types, and are used as model organisms in science. Mammals have been depicted in art since Paleolithic times, and appear in literature, film, mythology, and religion. Decline in numbers and extinction of many mammals is primarily driven by human poaching and habitat destruction, primarily deforestation. (Full article...)
The Arabian horse is a breed of horse with a reputation for intelligence, spirit, and stamina. With a distinctive head shape and high tail carriage, the Arabian is one of the most easily recognizable horse breeds in the world. It is one of the oldest horse breeds, with archaeological evidence of horses that resemble modern Arabians dating back 4,500 years. Throughout history, Arabian horses from the Middle East spread around the world by both war and trade, used to improve other breeds by adding speed, refinement, endurance, and good bone. Today, Arabian bloodlines are found in almost every modern breed of riding horse. The Arabian developed in a desert climate and was prized by the nomadic Bedouin people, often being brought inside the family tent for shelter and protection. This close relationship with humans has created a horse breed that is good-natured, quick to learn, and willing to please. But the Arabian also developed the high spirit and alertness needed in a horse used for raiding and war. This combination of willingness and sensitivity requires modern Arabian horse owners to handle their horses with competence and respect. "The Versatile Arabian" is a slogan of the breed. Arabians dominate the discipline of endurance riding, and compete today in many other fields of equestrian activity. They are one of the top ten most popular horse breeds in the world. Arabian horses are now found worldwide, including the United States and Canada, the United Kingdom, Australia, continental Europe, South America (especially Brazil), and its land of origin, the Middle East.

The eastern gray squirrel (Sciurus carolinensis) is a tree squirrel in the genus Sciurus, native to the eastern and midwestern United States, as well as to the southerly portions of the eastern provinces of Canada. A prolific and adaptable species, it has been introduced to and thrives in several regions of the western United States; it is also an invasive species in Britain, where it has spread across the country and largely displaced the native Eurasian red squirrel. The head and body can measure from 23 to 30 cm (9.1 to 11.8 in) and the tail from 19 to 25 cm (7.5 to 9.8 in) in length; its adult weight is between 400 and 600 g (14 and 21 oz). Like many members of the family Sciuridae, the eastern gray squirrel is a scatter-hoarder; it hoards food in numerous small caches for later recovery. In the United Kingdom and Canada, the species is simply referred to as the "grey squirrel".
This picture, taken in 2010, shows an eastern gray squirrel in Florida.
A male lion (Panthera leo) lying down in Namibia. One of the four "big cats" in the genusPanthera, the lion is the second largest cat, after the tiger. Males weigh between 150-250 kg (330-550 lb), and are easily recognizable by their manes. Though they were once found throughout much of Africa, Asia and Europe, lions presently exist in the wild only in Africa and India.
A newborn lesser short-nosed fruit bat (Cynopterus brachyotis) clinging upon a human finger. A species of megabat within the family Pteropodidae, it is a small bat that lives in South and Southeast Asia. Adults weigh between 21 and 32 grams (0.74 and 1.13 oz).
The steenbok (Raphicerus campestris) is a species of small antelope, generally standing 45–60 centimeters (16–24 inches) at the shoulder, commonly found in Africa. They live in a variety of habitats, from semi-desert to open woodland and thickets, and feed on low-level vegetation and roots. These common animals are typically solitary, except during mating season.
A juvenile Bennett's Wallaby (Macropus rufogriseus rufogriseus), a subspecies of the Red-necked Wallaby, on Maria Island, east of Tasmania. Red-necked Wallabies can be found in the more temperate and fertile parts of eastern Australia. They can weigh 13.8 to 18.6 kg (30 to 41 lb) and attain a head–body length of 90 cm (35 in), with the island version slightly smaller.
The leopard (Panthera pardus) is one of five extant species in the genus Panthera, a member of the cat family, Felidae. This photograph shows a leopard devouring an impala in Kruger National Park, South Africa. Compared to other wild cats, the leopard has a relatively large skull with powerful jaws, a long body and short legs. It can climb trees very skilfully, often rests on tree branches and can descend to the ground head first. An adult leopard is strong enough to drag a carcass heavier than itself up into a tree, where the prey may be eaten straight away or cached to be consumed later.
A female koala (Phascolarctos cinereus), an arborealherbivorousmarsupial native to coastal regions of eastern and southern Australia. The word "koala" comes from the Dharuk word gula. English-speaking settlers from the late 18th century first called it "koala bear" due to its similarity in appearance to bears, although they are not at all related. Instead, its closest living relative is the wombat.
The European wildcat (Felis silvestris silvestris) is a subspecies of the wildcat. It is native to the forests and grasslands of Europe, as well as Turkey and the Caucasus Mountains. Bulkier than both the African wildcat and the domestic cat, the European wildcat is also distinguished by its thick fur and non-tapered tail. Though it is predominantly nocturnal, the European wildcat may be active in the daytime in the absence of humans.
The tule elk (Cervus canadensis nannodes) is a subspecies of elk found only in California, seen here at Tomales Point in Point Reyes National Seashore. When Europeans arrived in the area, an estimated 500,000 tule elk roamed these regions, but the animals were thought to have been hunted to extinction by 1870. A single pair was discovered on the ranch of the cattle baron Henry Miller in 1874. He ordered his men to protect them, and is credited with the survival of the subspecies. As of 2019, the total Californian population is estimated to be 5,700.
A tabby is any cat that has a distinctive coat that features stripes, dots, lines or swirling patterns, usually together with a mark resembling an "M" on its forehead. Tabbies are not a cat breed, but a coat pattern found in many breeds of cat, as well as among the general mixed-breed population. The tabby pattern may be related to the coloration of the domestic cat's direct ancestor, the African Wildcat, which (along with the European Wildcat and Asiatic Wildcat) has a similar coloration. There are four genetically distinct tabby patterns: mackerel (shown here), classic, spotted, and ticked.
A portrait of a cheetah at Whipsnade Zoo in Bedfordshire. Cheetahs have small and streamlined heads. Their ears are small, short, and rounded, marked by black patches on the back and tawny edges. Their high-set eyes have round pupils, while their whiskers are fine and inconspicuous. Their faces have unique "tear streak" markings that may serve to reduce glare or define facial expressions.
Drymoreomys is a genus of South American rodent represented by a single species, D. albimaculatus. First formally described in 2011, the species prefers dense, moist, montane and premontane forest. Morphological evidence suggests they are tree dwellers.
An adult and a juvenile olive baboon (Papio anubis) at Queen Elizabeth National Park, Uganda. The most wide-ranging of all baboons, the olive baboon inhabits savannas, steppes, and forests in 25 countries throughout Africa. This highly adaptable species is omnivorous, feeding on a large variety of plants, invertebrates, small mammals, and birds.
