Canadian beaver

O maior roedor da América do Norte, o castor-canadense pode pesar até 32 kg e é um mestre engenheiro do ecossistema, habitando rios, lagos e áreas úmidas do Canadá e norte dos Estados Unidos. Ao derrubar árvores e construir barragens de até centenas de metros de comprimento, os castores criam lagoas que proporcionam habitat para centenas de espécies. Suas tocas e canais transformam bacias hidrográficas inteiras. Quase caçados até a extinção por sua pelagem, as populações de castor se recuperaram fortemente.
