Creature:Ornithorynchus proneoanatinus

Almost exactly the same as the Anatinus except that it has darker fur and walks lower to the ground. In fact, it is arguable that this is just a subspecies of Anatinus. However that is unlikley. The Proanatinus tends to have a lifespan three or four years longer than the Anatinus. This may be because its darker skin allows it to blend into the mud better. This protects it from predators like the Crocozard and the Buzzbeek. It appears that the Proanatinus and the Anatinus have a common ancestor. Perhaps an interstellar scientist took some Platypuses from Earth and tampered with its genes then released them on a random planet (Terrafermis). Who knows, maybe there are more species that haven't been discovered.
