The eastern one is called Platonas while flowing in the plain, Nerotrouvies in the gorge of the same name and Kanalaki in the area of ​​the waterfalls. The western branch is called Poros and is the one fed by the springs of the Nimfes. Some emblematic species of the river are the Eurasian Otter, the Epiros Riffle Daces and the fresh water crab.
