Abstract
Beavers are known as biggest rodents leaving in Europe and North America. Two species are included in beaver family: eurpoean beaver (Castor fiber, L.1758) and candian beaver (Castor canadensis, Kuhl 1820). In ancient times beavers existed in whole Europe and in the part of Asia, while their population in Europe decreased systematically from IX century on due to extensive hunts. Consequently, in the end of XIX century only few beavers groups existed in Europe. Within after second world war Poland numerically 130 specimens of European beaver were present. Since then on active protection of this species has started including many environmental programs. It resulted in systematic increase of beaver specimens. Currently beavers came back to their previous regions and some new regions are occupied as well. Their amount reaches over 89000 specimens. This manuscript presents detailed structure of beavers body and their physiology allowing to leave In both water and on land. Beavers natural feed, digestive track, digestive process are described as well. Issues related to reproduction and bringing up are described too. Natural predators are presented. Inside and outside parasites with their action are presented.
