The river is home to multiple endangered species, including the Iberian desman and the Cantabrian brown bear. Strabo made the first known historical reference to the river, calling it "Melsos." Ptolemy later referred to the river as the "Naelus" or "Nailos." This, in turn, would later morph into "Nilonis" and "Nalonis" in documents from the medieval Kingdom of Asturias, leading to its current denomination.[1]
