Herbivorous, the Siberian Ibex primarily feeds on alpine vegetation, grasses, and woody plants. It is particularly agile, capable of moving across rugged terrain and leaping between rocks with ease. While it was once heavily hunted for its valuable horns and meat, conservation efforts have helped stabilize its population, although the Siberian Ibex remains vulnerable due to habitat loss and poaching.

The Sperm Whale is the largest of the toothed cetaceans and the largest living marine predator today. It is easily recognizable by its massive head, which makes up about one-third of its total body length, and its streamlined body. This cetacean, which can reach up to 20 meters in length and weigh several dozen tons, is a deep-sea creature, primarily feeding on squid, including giant squids, which it hunts at extreme depths. The Sperm Whale is known for its long migrations, traveling thousands of kilometers between breeding grounds in the tropics and feeding areas in colder waters. Although it was intensively hunted for its oil and blubber in past centuries, it remains a protected species. The Sperm Whale also plays a crucial role in the marine ecosystem by regulating prey populations and maintaining the balance of food chains.

The Sika Deer is a medium-sized cervid, native to East Asia, that is distinguished by its spotted coat, especially visible in young individuals and females. Its coat ranges from light brown to reddish, often sprinkled with small white spots that help it blend into its forested environment.
