what is it?

The European water vole or northern water vole ( Arvicola amphibius , included in synonymy: A. terrestris ), is a semi-aquatic rodent. It is often informally called the water rat , though it only superficially resembles a true rat. Water voles have rounder noses than rats, deep brown fur, chubby faces and short fuzzy ears; unlike rats their tails, paws and ears are covered with hair.
