On the origin of the breed of black nutria aware that a nutria bred, we were in the territory of the Argentine possession. From standard representational forms, differences have almost no pets. Exterior characteristics and quality of reproductive almost identical. Black nutria have a beautiful, rich and smooth color of the whole body, and the undercoat is inherent dark gray background color. Near the area of the ear you can see the small tufts of wool, which have toning zone.

But even the standard nutria little different from the usual zonal toning inherent gray color schemes. With the maturation of the color coat woolen coats changed, and standard nutria color becomes much darker than the one who was born with the inherent right to nutria black color hairs.
