The Eurasian lynx is a medium-sized cat, ranging in length from 80 to 129 centimetres and weighing between 18 and 30 kilograms. It has powerful legs with large webbed and furred paws that act like snowshoes. It also has a short, bobbed tail with a black tip, black tufts of hair on its ears, and a long grey and white ruff. At birth, Eurasian lynx kittens weigh between 240 and 430 grams and are blind and helpless. The kittens begin to take solid food at six to seven weeks, when they start to leave the den. Kittens typically remain with their mothers until they are around 10 months old.
The Eurasian lynx is native to European and Siberian forests, where there are plenty of hideouts and opportunities for hunting and stalking. The hunting area of the lynx can be from 20 to 45 square kilometres, depending on the availability of prey. A lynx can cover up to 20 kilometres during one night's hunting. Those living in more mountainous areas may come down to the lowlands in winter to follow their prey, avoiding the deepest snows.
The Eurasian lynx is a solitary, secretive animal. It makes very quiet sounds and is hard to spot. It preys on hares, rabbits, rodents, grouse, wild boar, chamois, foxes and deer. Like other cats, it only takes on larger prey during winter, when there is less food available. Although it may hunt during the day when food is scarce, the Eurasian lynx is mainly nocturnal or crepuscular and usually spends the day sleeping in dense thickets or other hidden places.
