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 Pygmy Hippopotamus (Choeropsis liberiensis) is a large mammal native to the forests and swamps of western Africa (the scientific species classification means "of Liberia", as this is where the vast majority lives). The pygmy hippo is reclusive and nocturnal. It is one of only two extant species in the hippopotamidaefamily, the other being its much larger cousin the common hippopotamus. The pygmy hippopotamus displays many terrestrial adaptations, but like its larger cousin, it is semi-aquatic and relies on proximity to water to keep its skin moisturized and its body temperature cool. Behaviors such as mating and birth may occur in water or on land. The pygmy hippo is herbivorous, feeding on whatever ferns, broad-leaved plants, grasses and fruits it finds in the forests. A rare nocturnal forest creature, the pygmy hippopotamus is a difficult animal to study in the wild; it also lives primarily in countries with a great degree of civil strife. Pygmy hippos lead mostly solitary lives; they are sometimes seen in pairs or threesomes, but never large pods like the common hippopotamus. Unlike the common hippopotamus, they are not known to be territorial.

Female topi (Damaliscus lunatus jimela) in the Queen Elizabeth National Park in Uganda. A subspecies of the common tsessebe antelope, the topi is native to several countries in eastern Africa and lives primarily in grassland habitats, ranging from treeless plains to savannas. It is a tall species, with individuals ranging in height from 100 to 130 cm (39 to 51 in) at the shoulder. Predators of topi include lions and spotted hyenas, with jackals being predators of newborns.
The Eastern Grey Kangaroo (Macropus giganteus), native to southern and eastern Australia, is the most commonly encountered kangaroo species, as it can be found in and around the major cities within its range. Although males can typically reach a height of 2 metres (6.6 ft) and weigh around 66 kilograms (146 lb), and the scientific name translates to "gigantic large-foot", the Red Kangaroo is actually larger.
The Indian Palm Squirrel (Funambulus palmarum) is a squirrel native to India and Sri Lanka. It is relatively small, about the size of a rat, with three white stripes on its back from head to tail. According to Hindu legend, Lord Rama was so pleased with a squirrel's help in the construction of a bridge at Rameswaram that he stroked the squirrel's back and his fingers left their mark in the form of stripes.
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.
The brown-throated sloth (Bradypus variegatus) is the most common species of three-toed sloth. It is found in the forests of South and Central America. Males and females are both about 42–80 cm (17–31 in) in total body length and weigh 2.25–6.3 kg (5–14 lb).
The skull of a black rhinoceros (Diceros bicornis), a critically endangered species of rhinoceros native to eastern and central Africa. The two horns on the skull are made of keratin, with the larger front horn typically 50 cm (20 in) long. Sometimes, a third, smaller horn may develop.
The Nova Scotia Duck Tolling Retriever is a medium-sized retrieverdog breed that originated in southwestern Nova Scotia, Canada. It is named for its ability to lure waterfowl within gunshot range, called "tolling". It is particularly suited for retrieving in cold water climates because of its water-repellent double coat.
The impala (Aepyceros melampus) is a medium-sized African antelope. The name comes from the Zulu language. They are normally reddish-brown, with lighter flanks, white underbellies, and a characteristic "M" marking on the rear. Males have lyre-shaped horns, which can reach up to 90 cm (35 in) in length. They are strong jumpers, able to reach distances more than 10 m (33 ft) in a single bound. They are also fast runners, capable of reaching speeds up to 90 km/h (56 mph).
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.
Several female black-faced impala drinking at a waterhole. Impalas are sexually dimorphic. Females can weigh 10 to 25 kilograms (22 to 55 lb) less than males and do not have horns.
The Common Brushtail Possum (Trichosurus vulpecula) is the largest possum species and is perhaps the most widespread mammal in Australia. It grows to about 32–58 cm (13–23 in) in length, with an additional 24–40 cm (9–16 in) for its prehensile tail (seen here hanging below the branch). It is mainly a folivore, but has been known to eat small mammals such as rats. It is common in cities, having adapted well to human habitation.
Male lion (Panthera leo) and cub eating a Cape buffalo in Northern Sabi Sand, South Africa. Lions are true predators who can require an average of up to seven kilograms (15 lbs) of meat daily to survive. Large mammals comprise an important part of a lion's diet.
