🦫Canadian beaver
Der Kanadische Biber oder Amerikanische Biber (Castor canadensis) gehört zur Gattung Biber (Castor) aus der Ordnung der Nagetiere (Rodentia). Er ist nah mit dem Europäischen Biber (Castor fiber) verwandt und manche Zoologen betrachten beide als Unterarten nur einer Art. Allerdings ist er meist größer und er hat 40 Chromosomen, während der Europäische Biber 48 hat. Der kanadische Biber ist das Nationaltier Kanadas und auf der kanadischen Fünf-Cent-Münze abgebildet. Dennoch wird er in manchen Teilen Kanadas als Schädling betrachtet.
