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 humpback whale (Megaptera novaeangliae) is a baleen whale. One of the larger rorqual species, adults range in length from 12–16 metres (40–50 ft) and weigh approximately 36,000 kilograms (79,000 lb). The humpback has a distinctive body shape, with unusually long pectoral fins and a knobbly head. It is an acrobatic animal, often breaching and slapping the water. Males produce a complex whale song, which lasts for 10 to 20 minutes and is repeated for hours at a time. The purpose of the song is not yet clear, although it appears to have a role in mating. Found in oceans and seas around the world, humpback whales typically migrate up to 25,000 kilometres each year. Humpbacks feed only in summer, in polar waters, and migrate to tropical or sub-tropical waters to breed and give birth in the winter. During the winter, humpbacks fast and live off their fat reserves. The species' diet consists mostly of krill and small fish. Humpbacks have a diverse repertoire of feeding methods, including the spectacular bubble net feeding technique.
...that Scarlett the cat is a former stray cat whose efforts to save her kittens from a fire, at serious harm to herself, attracted worldwide media attention and has been related in a number of nonfiction books?

A female proboscis monkey (Nasalis larvatus) at Labuk Bay, Sabah, Malaysia. This monkey is endemic to Borneo. Though the female has a large nose, it is smaller than that of the male.
A female Parma Wallaby (Macropus parma) and her joey. This wallaby species is the smallest member of the genus Macropus, at between 3.2 and 5.8 kilograms (7.1 and 12.8 lb) and about 50 centimetres (1.6 ft) in length. It was believed to be extinct before the end of the 19th century, but a population was found on Kawau Island in 1965, and two years later another population was found in the forests near Gosford, New South Wales. They are now classified as Near Threatened.
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 domesticated yak at Yamdrok Lake in Tibet. The animals are important to Tibetan culture, and have been kept for thousands of years. The yaks are a method of transportation and serve as beasts of burden. Their feces are a source of fuel, and their milk can be used for butter, which is then made into sculptures or consumed.
An Indian palm squirrel (Funambulus palmarum) photographed in Bangalore, India. In India these squirrels are associated with the Hindu deity Rama, an avatar of Vishnu, and as such are not to be harmed. However, in Western Australia they are considered pests and at times targeted for eradication.
Skull of a male North Sulawesi babirusa, a species from the pig family endemic to Indonesia. Babirusas are notable for the long upper canines in the males that emerge vertically from the alveolar process, penetrating though the skin and curving backward over the front of the face and towards the forehead.
The yellow mongoose (Cynictis penicillata) is a small mammal averaging about 1 lb (1/2 kg) in weight and about 20 in (500 mm) in length. Found in southern Africa, it lives in flat areas ranging from semi-desertscrubland to grasslands. This carnivorous species lives in colonies of up to 20 individuals.
Dik-diks are antelopes in the genusMadoqua which can be found in the bushlands of eastern and southern Africa. These herbivores, named for the females' alarm calls, are quite small, measuring only 30–40 cm (12–16 in) at the shoulder, 50–70 cm (20–28 in) in length, and 3–6 kg (7–16 lb) in weight.
The European hedgehog (Erinaceus europaeus) is a species of hedgehog found in a wide range of habitat types in western Europe. It is a well-known species, and a favourite in European gardens, both for its endearing appearance and its preference for eating a range of garden pests. While populations are currently stable across much of its range, it is thought to be declining severely in Great Britain.
The jaw of Ambondro mahabo, seen in lingual view (from the side of the tongue). The scale bar is 1 mm (0.039 in) long. This mammal species is known only from this fragmentary lower jaw with three teeth, interpreted as the last premolar and the first two molars. It is the oldest known mammal with putatively tribosphenic teeth.
The olive baboon (Papio anubis) is an Old World monkey found in 25 countries throughout Africa, making it the most widely ranging of all baboons. It is named for its coat, which, at a distance, is a shade of green-grey. At closer range, its coat is multi-colored, due to rings of yellow-brown and black on the hairs. It is omnivorous, finding nutrition in almost any environment, and able to adapt with different foraging tactics.
