The American pika is a small lagomorph mammal, 15–23 cm in length, with a stocky body, short limbs, and small rounded ears, covered in brownish-gray fur. It inhabits alpine rocky slopes and talus fields of North America, from British Columbia to New Mexico, at elevations of 1400–3800 m, feeding on mosses, grasses, and leaves.

The Arctic Fox is a small carnivore found in the Arctic regions, primarily in Alaska, Canada, Scandinavia, and Russia. It measures about 45 to 50 cm in length, with a tail of 30 to 35 cm, and weighs between 3 and 9 kg, depending on the seasons. Its fur is typically white in winter, allowing it to camouflage in the snow, while it takes on a more brown or grayish hue in summer to blend in with the rocky and grassy landscapes. The Arctic Fox is an opportunistic omnivore, feeding on small mammals, birds, eggs, fruits, and berries. Although well adapted to the extreme living conditions of the Arctic, it is threatened by climate change, which is altering its natural habitat and the availability of its prey.

The Vulpes vulpes alascensis, or Alaskan Red Fox, is a subspecies of the red fox found primarily in coastal and interior regions of Alaska. This fox is well adapted to cold climates, with a dense and thick coat that protects it from extreme temperatures. Its fur ranges from bright red to dark brown, with a characteristic bushy tail. An opportunistic feeder, it preys on small mammals, birds, insects, and occasionally fruits. Although primarily nocturnal, it can be seen at dawn and dusk. The Alaskan Red Fox is a solitary animal, except during the breeding season. It is known for its intelligence and ability to adapt to various environments, allowing it to survive in harsh conditions.

The African straw-coloured fruit bat is a fruit-eating bat species native to sub-Saharan Africa. This bat is easily recognizable by its golden or straw-colored fur, which helps it blend into the foliage during the day. The African straw-coloured fruit bats primarily feed on fruits, nectar, and pollen, playing a crucial role in pollinating plants. They form large colonies and are often seen in flight at dusk as they head out to search for food. These bats can also travel long distances, making them adaptable to a wide range of habitats.

The Arabian tahr, Hemitragus jayakari, is a species of wild goat native to the arid mountains of Oman and the United Arab Emirates. This robust mammal is well adapted to rugged, rocky terrains, where it primarily feeds on grasses, leaves, and fruits. Males are distinguished by their thick, curved horns, while females have smaller horns. Its dense, brownish coat allows it to blend into its rocky environment. The Arabian tahr is a gregarious animal, living in small groups, although adult males are often solitary. This species is threatened by habitat loss and hunting, leading to its classification as vulnerable by the IUCN.

The American mink, Neovison vison, is a small carnivorous mammal belonging to the Mustelidae family. Native to North America, it has been introduced to various parts of the world for the fur industry. This mustelid is recognizable by its dense, glossy fur, typically dark brown, and its slender silhouette. It measures between 30 and 45 cm, excluding its tail, which can reach 25 cm. The mink is an excellent swimmer and is often found near water bodies like rivers, lakes, and marshes. It primarily feeds on fish, small mammals, birds, and amphibians. Although solitary and territorial, it may occasionally share its territory with other minks.
