Eurasian wolves (Canis lupus lupus) represent a subspecies of the gray wolf, which is widely distributed across Eurasia, encompassing a vast range from Western Europe all the way to Eastern Russia. They are one of the largest wolf subspecies, with their size and weight varying significantly across their range due to differences in habitat, prey availability, and climate. Typically, these wolves have a body length ranging from 105 to 160 centimeters (41 to 63 inches), and an average weight for males between 40 to 50 kilograms (88 to 110 pounds), though individuals in some regions may be larger.

Eurasian wolves have adapted to a variety of habitats, including forests, mountains, tundras, and grasslands. Their fur color also varies considerably, from grey to brown, reflecting their adaptability to different environments. These wolves play a crucial role in their ecosystems as apex predators, regulating the populations of a wide range of prey animals, from ungulates like deer and elk to smaller mammals.

Social animals, Eurasian wolves live in packs typically comprising 5 to 12 members, although larger packs are known in areas with abundant prey. These packs are complex social units that hunt, raise pups, and defend territories together. Communication within and between packs is sophisticated, involving vocalizations such as howling, as well as body language and scent marking.

Eurasian wolves have a rich history in human culture, featuring prominently in folklore and mythology across their range. Despite their ecological importance, they have faced challenges due to habitat loss, human encroachment, and persecution. Efforts are being made in various countries to conserve their populations through legal protection, habitat restoration, and public education campaigns to mitigate humanwolf conflicts.

The conservation status of Eurasian wolves varies by region, with some populations stable or increasing thanks to these conservation efforts, while others remain threatened. Their adaptability has allowed them to survive in a wide range of conditions, but continued conservation efforts are essential to ensure the longterm viability of Eurasian wolf populations across their historic range.
