Eurasian beaver

The furry flat-tailed mammal that builds its own aquatic empire

Nasser Halaweh

Also known as the European beaver, it is the largest rodent in Europe. These semi-aquatic mammals can weigh up to 32 kg (70 pounds) and can grow to be over 36 in (3 ft) long, with a flat paddle-shaped tail that they use for swimming. They have a thick brown fur coat and webbed feet that enable them to move effortlessly in the water.

Eurasian beavers are herbivores and feed on a variety of plants, including tree bark, leaves, and roots. They are known for their impressive engineering skills, building complex dams and lodges with mud, sticks, and branches to create their ideal habitat. These lodges can have underwater entrances, protecting them from predators and providing warmth during winter months. Once on the brink of extinction, the Eurasian beaver has made a remarkable recovery, and their populations are thriving in many parts of Europe.
