Cephalic arteries of 17 European beavers Castor fiber Linnaeus, 1758 were examined. After the common carotid arteries were injected with resin, the heads were biologically macerated. Differences between individual specimens as well as asymmetrical distribution of certain arteries were noted. It was found that in the European beaver the common carotid artery divided into external and internal carotid arteries. The internal carotid artery is well developed in C. fiber, whereas in some other rodents it may be obliterated. The examined beavers had no stapedial arteries.
