🐭Nutria
Die (selten: das) Nutria (Myocastor coypus), auch Biberratte oder seltener Sumpfbiber, Schweifbiber, Schweifratte oder Coypu genannt, ist eine aus Südamerika stammende und in Mitteleuropa angesiedelte Nagetierart. Sie wird entweder in einer eigenen Familie, Myocastoridae, oder als Unterfamilie Myocastorinae innerhalb der Stachelratten (Echimyidae) eingeordnet. Nach neueren molekularen Analysen (aufgrund homologer DNA-Sequenzen, mitochondrialer und nuklearer Gene) gehört die Gattung unzweifelhaft zu den Echimyidae. Sie ist der einzige wasserlebende (semiaquatische) Vertreter in einer Gruppe sonst bodenlebender Gattungen. Die Nutria wird gelegentlich mit der aus Nordamerika stammenden Bisamratte verwechselt, die sich gleichfalls in Europa als Neozoon etabliert hat, allerdings kleiner ist und einen seitlich abgeplatteten Schwanz hat.
