Zootomical terms of location overlap considerably with terms used in human anatomy. In animals, the head end is called the "cranial end" and the tail end is the "caudal end". The side of the body normally oriented upwards is the "dorsal" side; the opposite side, typically the one closest to the ground when walking on all legs, swimming or flying, is the "ventral" side.

A newborn joey (baby kangaroo) in its mother's pouch. Kangaroo babies are born at a very early stage of development after a gestation of 31-36 days. At this stage, only the forelimbs are somewhat developed, to allow the newborn to climb to the pouch and attach to a teat. It will not re-emerge for several months, during which time it develops fully.

The Common Raccoon (Procyon lotor) is a widespread, medium-sized, omnivorous mammal of North America. It has black facial colorings around the eyes, and has a bushy tail with light and dark alternating rings. The coat is a mixture of gray, brown, and black fur. The characteristic eye colorings make the animal look like it is wearing a "bandit's mask," which has enhanced the animal's reputation for mischief, vandalism, and thievery.
A male lion (Panthera leo) lying down in Namibia. One of the four "big cats" in the genus Panthera, 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 dromedary or one-humped camel (Camelus dromedarius) in the Australian Outback. Estimated populations of Australian feral camels are in the hundreds of thousands, and this is now the world's only population of dromedaries exhibiting wild behaviour. Thousands of camels were imported into Australia between 1840 and 1907 to open up the arid areas of central and western Australia. They were used for riding, and as draught and pack animals for exploration and construction of rail and telegraph lines; they were also used to supply goods to remote mines and settlements. Their impact on the environment is not as bad as that of other introduced pests in Australia. They prefer to eat trees and plants that local wildlife dislike; only 2% of their diet is grass.

A close-up view of a cheetah (Acinonyx jubatus) cub. Unlike some other cats, the cheetah is born with its characteristic spots, as well as a downy underlying fur on their necks extending to mid-back, which gives the cub the appearance of the Honey Badger, to scare away potential aggressors. Despite this, up to 90% of cheetah cubs are killed by predators in the early weeks of life. Healthy adult cheetahs have few predators because of their speed.

A portrait of a Plains Zebra (Equus quagga), the most common and widespread species of zebra. The unique stripes and behaviors of zebras make these among the animals most familiar to people. They can be found in a variety of habitats throughout Sub-Saharan Africa. The name "zebra" comes from the Old Portuguese word zevra which means "wild ass". Zebra stripes are typically vertical on the head, neck, forequarters, and main body, with horizontal stripes at the rear and on the legs of the animal. It was previously believed that zebras were white animals with black stripes. Embryological evidence, however, shows that the animal's background color is black and the white stripes are additions.
The meerkat (Suricata suricatta) is a small member of the mongoose family native to the Kalahari Desert of southern Africa. They are social animals, living underground in groups of 20 to 50 members. Although the name means "lake cat" in Dutch, meerkats are not cats, nor are they attracted to lakes.
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.

A female koala (Phascolarctos cinereus), an arboreal herbivorous marsupial 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.

Sometimes referred to as a "rat-kangaroo", it is relatively small, rarely exceeding 2 kg (4.4 lb), but will travel up to 1.5 km (0.93 mi) from its nest to find food.
A cast of the extinct hominid species Sahelanthropus tchadensis holotype cranium, dubbed "Toumaï", in facio-lateral view. The original cranial fragment is dated to about 7 million years ago and was discovered in Chad. Other than Toumaï, the only Sahelanthropus remains to be discovered are five pieces of jaw and some teeth.
Two olive baboons (Papio anubis) engaged in social grooming, an activity that social animals (including humans) engage in to clean or maintain one another's body or appearance. Grooming also reinforces social structures, family links, and builds relationships. It has been best studied among primates, but insects, birds, fish, and other mammals are known to engage in it as well.
The warthog (Phacochoerus africanus) is a wild member of the pig family that lives in grassland, savanna, and woodland in Sub-Saharan Africa. The common name comes from the four large wart-like protrusions found on the head of the warthog, which serve as a fat reserve and are used for defence when males fight.
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).

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.

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 kob (Kobus kob) is an antelope found across Central Africa and parts of West Africa and East Africa. It is closely related to the reedbucks and waterbucks and similar in appearance to the impala but more heavily built. Kob have few strong social bonds, but females can live in herds numbering in the thousands. Males are generally territorial, although on densely-populated floodplains some males live in clustered territories known as leks.

The polar bear (Ursus maritimus) is a hypercarnivorous bear whose native range lies largely within the Arctic Circle, encompassing the Arctic Ocean, its surrounding seas and surrounding land masses. A boar (adult male) weighs around 350–750 kilograms (770–1,650 lb), while a sow (adult female) is about half that size. Polar bears are the largest land carnivores currently in existence, rivalled only by the omnivorous Kodiak bear. Although it is the sister species of the brown bear, it has evolved to occupy a narrower ecological niche, with many body characteristics adapted for cold temperatures, for moving across snow, ice and open water, as well as for hunting seals, which make up most of its diet. Although most polar bears are born on land, they spend most of their time on sea ice. The species's scientific name, which is derived from this fact, means 'maritime bear'. Because of their dependence on sea ice, polar bears are categorized as marine mammals. Due to expected habitat loss caused by global warming, the polar bear is classified as a vulnerable species. For decades, large-scale hunting raised international concern for the future of the species, but populations have rebounded after controls and quotas began to take effect.

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".

The greater kudu (Tragelaphus strepsiceros) is a species of woodland antelope in the genus Tragelaphus found throughout eastern and southern Africa. Despite occupying widespread territory, they are sparsely populated in most areas due to declining habitat, deforestation and poaching. The greater kudu is one of two species commonly known as kudu, the other being the lesser kudu, T. imberbis. Greater kudus have a narrow body with long legs, and their coats can range from brown or bluish grey to reddish brown. They possess between four and twelve vertical white stripes along their torso. The head tends to be darker in colour than the rest of the body, and exhibits a small white chevron running between the eyes. The helical horns of adult males grow as the animal ages, reaching 2+1⁄2 rotations at about 6 years old.
This picture shows a greater kudu bull photographed near Groot Okevi in Etosha National Park, Namibia. Bulls weigh 190–270 kg (420–600 lb), up to a maximum of 315 kg (690 lb), and stand up to 160 cm (63 in) tall at the shoulder.

The Cape ground squirrel (Xerus inauris) is a medium-sized rodent native to South Africa, Namibia and Botswana. They live in social groups of up to three adult females and several sub-adults. The species mainly inhabits arid or semi-arid areas, preferring velds and grasslands with compact soil, and can also be found in scrub, on floodplains and in agricultural areas. Males live independently, only joining groups when there is a female in estrus. Ever alert to danger, they can drive off predators such as snakes by engaging in mobbing behavior.

The southern plains gray langur (Semnopithecus dussumieri) is a species of Old World monkey native to the Indian subcontinent. It is about 62 cm (24 in) tall and lives in groups in various forest habitats, feeding mainly on leaves, fruit and flowers in the canopy, supplementing these with insects, gum, grasses, herbs and roots. The monkeys are considered sacred in India, and some are used by Hindu priests for religious purposes. They have adapted to living in close proximity to humans in urban settings; they are often fed by humans and accept cakes, millet, and other foods. The species is protected by law in India, but some are still persecuted for damaging crops, hunted for food and captured for pets.
This photograph of a female southern plains gray langur was taken in Kanha Tiger Reserve, in the Indian state of Madhya Pradesh. The park was created on 1 June 1955 and was designated a tiger reserve in 1973.

The Tadoba Andhari Tiger Reserve is the largest national park in the state of Maharashtra in central India. Most of the reserve consists of natural dry deciduous forests, however parts have been cleared for firewood or grazing land. Besides tigers, there are Indian leopards, sloth bears, gaurs, nilgais, dholes, striped hyenas, small Indian civets, jungle cats, sambars, muntjacs, chitals, chousinghas and honey badgers. There are also villages in the reserve, and although cattle grazing is not allowed in the core zone, some livestock inevitably stray inside. In 2013, at least four people and thirty to fifty cattle were killed by leopards, tigers and sloth bears. This picture shows a Bengal tigress named Maya photographed in the reserve.
The llama (Lama glama) is a domesticated South American camelid, widely used as a meat and pack animal by Andean cultures since the pre-Columbian era. A full-grown llama can reach a height of 1.7 to 1.8 metres (5 ft 7 in to 5 ft 11 in) at the top of the head, and can weigh between 130 and 200 kilograms (290 and 440 lb). At birth, a baby llama (known as a cria) can weigh between 9 and 14 kilograms (20 and 31 lb). Llamas typically live for 15 to 25 years, with some individuals surviving 30 years or more. This photograph shows a dam (female llama) and her cria at Laguna Colorada in Eduardo Avaroa Andean Fauna National Reserve, Bolivia.

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.

The cheetah (Acinonyx jubatus) is a large cat native to Africa and central Iran. Cubs are highly vulnerable to predators during the first few weeks of life, and predation is the leading cause of mortality among cheetah cubs. A study showed that in areas with a low density of predators (such as Namibian farmlands) around 70 per cent of the cubs survived beyond the age of 14 months, whereas in areas like the Serengeti National Park, where several large carnivores exist, the survival rate was just 17 per cent. This cheetah cub was photographed in the Phinda Private Game Reserve in KwaZulu-Natal, South Africa, amid long grass.
