Lepus timidus
- Arctic hare young are born covered in thick fur and immediately sighted, and on the very first day of life they are already able to move around independently.
- The load per 1 cm² of the arctic hare's footpad is 8.5–12 g, allowing it to move across loose snow. The load is significantly higher in the fox, wolf, and greyhound.
- During breeding, female arctic hares emit a special cry — a cooing sound — to attract males. This occurs twice a year: in February–March and in May–June.
- The arctic hare in the tundra of Western Siberia reaches a weight of up to 5.5 kg, which is greater than that of arctic hares in Yakutia and the Far East, where their weight does not exceed 3 kg.
- Arctic hare young reach sexual maturity at 10 months and can reproduce.
- The arctic hare (Lepus timidus) has been acclimatized in South America, including Chile and Argentina.
- The mountain hare turns completely white in winter except for the black tips of its ears.
- It can run at up to 60 km/h and make sharp turns.
- The hare is nocturnal and feeds on bark and shoots in winter.
- In captivity it has lived about 5–7 years.
Yaş
The Alpine hare typically lives from 3 to 8 years, although the maximum lifespan can reach 18 years, and the theoretical lifespan ranges from 9 to 18 years; the species reaches sexual maturity between 9 months and 1 year. The young are born with their eyes open and begin walking immediately. During the embryonic stage, the fetus develops inside the mother for approximately 50 days and does not feed independently. The newborn, a young hare, is covered in fur, has its eyes open, and begins to eat grass within a few weeks; this stage lasts from 1 day to 1 year. Following this, the species enters the adult stage, which lasts from 1 to 11 years, during which time it can reproduce and lives independently.
Fenotip
The young mountain hare has grey-brown fur for camouflage among grass and bushes; adult individuals' fur changes color seasonally, being white in winter for camouflage on snow and grey-brown in summer, with a change occurring during molting. The species’ ears are long, enabling them to detect sounds of predators from a great distance. Strong hind legs allow the animals to make long jumps and escape quickly.

The Dalmatian pelican is a bird species with a body height ranging from 68 to 75 cm and a body length ranging from 45 to 65 cm; the mass of an adult Dalmatian pelican varies from 3.97 to 4.23 kg. At the "Embryo" stage, body mass ranges from 0 to 40 g, and body length ranges from 0 mm to 5 cm, while at the "Chick" stage, body mass reaches from 80 g to 1.8 kg, and body length ranges from 15 to 45 cm. An adult Dalmatian pelican has a body mass ranging from 2 to 5 kg and a body length ranging from 45 to 65 cm.
Yaşayış mühiti
The mountain hare inhabits elevations up to 3 kilometers and is found in flooded meadows where water frequently covers the land and there is abundant grass, taiga with cold winters and many coniferous trees such as spruce and pine, and tundra characterized by very cold temperatures, short summers, few trees, and plentiful moss. The species occupies terrestrial landscapes including highlands and tundra, ground forests, and alpine tundra, experiencing a cool summer with temperatures of 15 to 20 degrees Celsius, consistently high humidity with frequent rainfall, snowy winters, and tundra conditions with very cold temperatures and short summers.
Sığınacaq
The mountain hare lives on the ground among grass, bushes, or snow; the species does not have a permanent or long-term shelter. It lacks a fixed refuge and uses grass for protection from predators and for resting.
Coğrafiya
The mountain hare is found within the Palearctic biogeographical region, inhabiting several distinct ecosystems including Celtic broadleaf forests, Sarmatian mixed forests, Scandinavian mountain birch forests and meadows, Ural mountain forests and taiga, the Scandinavian-Russian taiga, and West Siberian taiga.
Qida
The mountain hare is an herbivore, consuming only plants; during summer, it eats grass and leaves, while in winter, it feeds on branches, bark, and shoots of bushes. The species obtains food by gnawing on plants and employs foraging and grazing strategies to find sustenance. Its diet includes grass, leaves, young shoots, tree bark, bush branches, young shoots and sprouts, wood, and bark. A young hare is fed milk. The daily food requirement ranges from 300 grams to 0.6 kilograms. Predators of the species include wolverines, eagles, golden eagles, and wolves. In some cultures, the animal is consumed, but it is not considered kosher.
Çoxalma
The Caucasian snow vole is a terrestrial species, developing outside of water bodies, reproducing through conventional sexual means with fertilization and without alternating generations. Embryonic development lasts 1 month 3 weeks; females give birth to from 2 to 5 offspring, with an interbirth interval of from 1 month 1 week to 1 month 3 weeks. Live young are born on land, sighted, and covered in fur, and the mother feeds them milk for several weeks. Eggs, larvae, or young can develop in a terrestrial nest located on or near the ground, lying directly on the soil surface without shelter. The nest is situated directly on the ground surface, and only the mother exhibits parental care. Females give birth multiple times during the warm season, and sexual maturity occurs from 8 months to 1 year.
