Lion
Panthera leo
The lion is a large cat of the genus Panthera, currently ranging only in Sub-Saharan Africa and India. It has a muscular, broad-chested body; a short, rounded head; round ears; and a dark, hairy tuft at the tip of its tail. It is sexually dimorphic; adult male lions are larger than females and have a prominent mane that extends from the head to the shoulders and chest.

Tiger
Panthera tigris
The tiger is a large cat and a member of the genus Panthera native to Asia. It has a powerful, muscular body with a large head and paws, a long tail and orange fur that fades to white in parts, with black, mostly vertical stripes. It is traditionally classified into nine subspecies, though some recognise only two subspecies, the mainland Asian tiger and the Sunda Islands tiger.

Leopard
Panthera pardus
The leopard is one of the five extant cat species in the genus Panthera. It has a pale yellowish to dark golden fur with dark spots grouped in rosettes. Its body is slender and muscular, reaching a length of 92–183 cm (36–72 in) with a 66–102 cm (26–40 in) long tail and a shoulder height of 60–70 cm (24–28 in). Males typically weigh 30.9–72 kg (68–159 lb), and females 20.5–43 kg (45–95 lb).

Jaguar
Panthera onca
The jaguar is a large cat species and the only living member of the genus Panthera that is native to the Americas. Its distinctively marked coat features pale yellow to tan colored fur covered by spots that transition to rosettes on the sides, although a melanistic black coat appears in some individuals. With a body length of up to 1.85 m and a weight of up to 158 kg (348 lb), it is the biggest cat species in the Americas and the third largest in the world. The jaguar's powerful bite allows it to pierce the carapaces of turtles and tortoises, and to employ an unusual killing method: it bites directly through the skull of mammalian prey between the ears to deliver a fatal blow to the brain.

Cheetah
Acinonyx jubatus
The cheetah is a species of large feline and the only living member of the genus Acinonyx. The cheetah is a pursuit predator and the fastest land animal, capable of running at 93–104 km/h (58–65 mph); it has evolved for speed, having powerful hindlimb muscles, long limbs and a flexible spine. The cheetah has a tawny to creamy white or pale buff fur that is marked with evenly spaced, solid black spots. The head is small and rounded, with a short snout and black tear-like facial streaks. It has a height of 67–94 cm (2.20–3.08 ft) at the shoulder, and the head-and-body length is between 1.1 and 1.5 m. Adults weigh between 21 and 65 kg.

Cougar
Puma concolor
The cougar, also called puma, mountain lion, catamount, and panther, is a large feline native to the Americas. It inhabits North, Central and South America, making it the most widely distributed wild, terrestrial mammal in the Western Hemisphere, and one of the most widespread in the world. Its range spans Yukon, British Columbia and Alberta in Canada, the Rocky Mountains and areas in the western United States. Further south, its range extends through Mexico to the Amazon rainforest and the southern Andes Mountains in Patagonia. It is an adaptable generalist species, occurring in most American habitat types. It prefers habitats with dense underbrush and rocky areas for stalking but also lives in open areas.

Lynx
Lynx lynx
The Eurasian lynx is one of the four extant species within the medium-sized wild cat genus Lynx. It is widely distributed from Northern, Central and Eastern Europe to Central Asia and Siberia, the Tibetan Plateau and the Himalayas. It inhabits temperate and boreal forests up to an elevation of 5,500 m (18,000 ft). Despite its wide distribution, it is threatened by habitat loss and fragmentation, poaching and depletion of prey.

Wolf
Canis lupus
The wolf, also known as the grey wolf or gray wolf, is a canine native to Eurasia and North America. More than thirty subspecies of Canis lupus have been recognized, including the dog and dingo, though grey wolves, as popularly understood, include only naturally occurring wild subspecies. The wolf is the largest wild extant member of the family Canidae, and is further distinguished from other Canis species by its less pointed ears and muzzle, as well as a shorter torso and a longer tail. The wolf is nonetheless related closely enough to smaller Canis species, such as the coyote and the golden jackal, to produce fertile hybrids with them. The wolf's fur is usually mottled white, brown, grey, and black, although subspecies in the arctic region may be nearly all white.

Coyote
Canis latrans
The coyote is a species of canine also known as the American jackal, prairie wolf, and brush wolf. It is native to North America, and it is smaller than its close relative, the gray wolf, and slightly smaller than the closely related eastern wolf and red wolf. It fills much of the same ecological niche as the golden jackal does in Eurasia but the coyote is generally larger.

Polar Bear
Ursus maritimus
The polar bear is a large bear native to the Arctic and nearby areas. It is closely related to the brown bear, and the two species can interbreed. The polar bear is the largest extant species of bear and land carnivore by body mass, with adult males weighing 300–800 kg (660–1,760 lb). The species is sexually dimorphic, as adult females are much smaller. The polar bear is white or yellowish-furred with black skin and a thick layer of fat. It is more slender than the brown bear, with a narrower skull, longer neck and lower shoulder hump. Its teeth are sharper and more adapted to cutting meat. The paws are large and allow the bear to walk on ice and paddle in the water.

Panda
Ailuropoda melanoleuca
The giant panda, also known as the panda bear or simply panda, is a bear species endemic to China. It is characterised by its white coat with black patches around the eyes, ears, legs and shoulders. Its body is rotund; adult individuals weigh 100 to 115 kg and are typically 1.2 to 1.9 m long. It is sexually dimorphic, with males being typically 10–20% larger than females. A thumb is visible on its forepaw, which helps in holding bamboo in place for feeding. It has large molar teeth and expanded temporal fossae to meet its dietary requirements. It can digest starch and is mostly herbivorous with a diet consisting almost entirely of bamboo and bamboo shoots.
