The Eurasian Brown Bear is a large bear found in the forests and mountains of Europe and northern Asia. Recognized by its powerful build, thick brown fur, and impressive claws, it feeds on berries, roots, fish, insects, and mammals. As an omnivore, it plays an important role in maintaining healthy ecosystems by dispersing seeds and regulating prey populations. Many Eurasian Brown Bears hibernate during the winter, emerging in spring to forage for food.

The Reindeer, also known as the Caribou in North America, is a hardy deer found across the Arctic and subarctic regions of Europe, Asia, and North America. Recognized by its thick coat and broad hooves, it is the only deer species in which both males and females regularly grow antlers. Reindeer feed on lichens, grasses, mosses, and shrubs and are famous for their long seasonal migrations. They play an important role in Arctic ecosystems and have supported Indigenous cultures for thousands of years.

The Siberian Tiger, also known as the Amur Tiger, is the largest tiger subspecies, found in the temperate forests of the Russian Far East and northeastern China. Recognized by its thick orange coat with bold black stripes and pale underparts, it is well adapted to cold climates. A solitary apex predator, the Siberian Tiger hunts deer, wild boar, and other large mammals, playing a vital role in maintaining healthy forest ecosystems. Conservation efforts have helped stabilize its population, though habitat loss and poaching remain significant threats.

The Polar Bear is the world's largest land carnivore, found throughout the Arctic. Recognized by its thick white fur, black skin, and powerful body, it is superbly adapted to life on sea ice and depends primarily on seals for food. An excellent swimmer, the Polar Bear can travel long distances across icy waters in search of prey. Climate change and the loss of Arctic sea ice pose the greatest threats to its long-term survival.

The Baikal Seal is the world's only seal species found exclusively in freshwater, living only in Lake Baikal. Recognized by its sleek silver-gray coat and large dark eyes, it feeds mainly on fish and other aquatic animals. Baikal Seals are excellent divers, capable of reaching great depths while searching for food beneath the lake's ice-covered waters. As one of the few landlocked seal species, they are a unique symbol of Lake Baikal's remarkable biodiversity.

The Spoon-billed Sandpiper is a tiny migratory shorebird recognized by its unique spoon-shaped bill. It breeds in the Arctic regions of northeastern Russia and migrates to coastal wetlands across South and Southeast Asia for the winter. Feeding on small crustaceans, insects, and other invertebrates, it forages by sweeping its specialized bill through shallow mud and water. Habitat loss, coastal development, and climate change have made the Spoon-billed Sandpiper critically endangered.
