Mammal

The bush dog (or Speothos venaticus), also known as the vinegar dog, is a small species of canid found near the pools and rivers of forests, wetlands, savannahs, and pasture of South America. It has a squat, stocky build with short legs and tail, a rounded head and snout with small round ears. It has brown fur covering its body, with tan fur on its head and black fur on its legs and tail. The bush dog measures 57cm to 75cm in length, 20cm to 30cm in height and weighs 5kg to 8kg.

The bighorn sheep (or Ovis canadensis) is a species of wild sheep that lives in the mountains, grasslands and deserts of Canada, the USA, and Mexico. They are pale grey to dark brown in colour, with yellow-brown horns. There are several subspecies and populations of bighorn sheep, whose colour, build and size can change based on the environment in which they live. The bighorn sheep is sexually dimorphic, with the males being heavier than the females and having much thicker and curlier horns.

Native to Eastern and Southern Africa, Kirk's dik-dik (or Madoqua kirkii) is a small antelope adapted to live in open grasslands. Giving them a delicate appearance, the short body rests on thin legs, the hind legs being longer. The head is small, with a pointy snout and large, round eyes. Males have short horns which may be covered partially or wholly by the tuft of hair on the forehead. The short fur is brown, gradually greying towards the back and hindquarters and a lighter shade on the belly. Males and females look alike except for the male's horns.

The markhor (or Capra falconeri) is a large goat from Central Asia, which is also sometimes called the screw-horned goat. They are stocky creatures with sturdy, barrel-shaped bodies. Their cloven hooves allow them to climb steep mountains and cliffs. They are covered in thick fur, which is grey-brown for males and a lighter, richer brown in females. A primitive black stripe follows the spine, and legs and face have dark markings. Males have a long, shaggy beard along the entire length of the neck. Both sexes carry thick, curled horns, which are significantly longer in males.

The spectacled bear (or Tremarctos ornatus) is a medium-sized bear native to the Andes regions of South America. It has thick, black fur with white markings on face and chest. The face is relatively flat compared to other bears, showing its close relationship with the extinct short-faced bears. Like other bears, the spectacled bear is highly sexually dimorphic, with the female being much smaller than the male. Male spectacled bears stand 76cm to 91cm tall at the shoulder and weigh 100kg to 200kg, while females are 60cm to 73cm tall and weigh only 35kg to 82kg.

Pallas's cat (or Otocolobus manul), also known as the manul, is a small wild cat native to Central and East Asia, its range limited to the West by the Caucasus mountains and to the South by the Himalayas. Its most striking feature is the incredibly dense and long fur that give it a chubby, plush appearance. The coat is grey with beige to rusty red shades, with sparse black tabby markings. The head is small and round, with small triangular ears emerging from the thick ruff around it.

The hamadryas baboon (or Papio hamadryas) is a species of baboon, a large and mostly terrestrial primate, native to Ethiopa, Djibouti and Somalia in the Horn of Africa and Yemen on the Arabian Peninsula. Hamadryas baboons exhibit extreme sexual dimorphism not just in size, but also appearance. Both sexes are covered in shaggy fur, which is brown in females and silvery-white in males. Additionally, males have a thick mane, or cape, around the neck and a ruff of hair around the cheeks. With a dog-like snout, the face is hairless and red-brown in colour.

Found only in the Northwestern rainforests of Madagascar, Coquerel's sifaka (or Propithecus coquereli) is a Critically Endangered, medium-sized species of Lemur. Their body is covered in distinctly coloured fur that is white with dark red patches along the limbs, chest, and back, which may fade into grey fur along the tail. The face is black, with yellow eyes and a white stripe on the nose, and is framed by a short white ruff. No distinct sexual dimorphism occurs in this species, with both sexes looking alike, although females are sometimes reported to grow slightly larger than males.

The African leopard (or Panthera pardus pardus) is the nominate subspecies of the leopard, native to Central and Southern Africa. It has a slender build with an elegant head. The base coat colour ranges from yellow to dark golden and is covered in small, tightly spaced rosettes that turn into black spots towards the lower body, face, and tail tip. The underside and inside of the legs are white. The African leopard is sexually dimorphic, with males being larger and heavier than females.

The American standard donkey (or Equus africanus asinus) is a type of North American donkey that is domesticated. North American donkeys are classified by their size rather than their pedigree in order to determine their type (as opposed to a specific breed) due to the diverse genetic influences of their ancestors – donkeys that were imported to the Americas from all over the Old World from the fifteenth century onward. The American standard donkey is 1.2m to 1.4m tall at the withers and weighs between 180kg and 227kg.
