The
nutria (Myocastor coypus) belongs to the
class of Mammals, Rodents order, family Myocastoridae. It leads a semiaquatic lifestyle and can be seen around
rivers, lakes and marshes. Nutria is the biggest rodent in Bulgaria.
It
lives mainly along the rivers of southeastern Bulgaria. The animal’s body is
cylindrical in shape, with relatively large head and short ears. The peak of
the face is blunted with clearly visible teeth, colored in bright orange.
Nutrias are mostly herbivores. Their role is to spread diseases such as equine
encephalomyelitis, leptospirosis, hemorrhagic septicemia (Pasteurellosis), paratyphoid and salmonellosis. The aim of the
study is to examine the impact of nutria on the environment on the territory of
Stara Zagora region, and some of its biological and anatomical features. In
some territories of Stara Zagora were found traces of life activity of nutria,
as entrances of shelters, footprints of thoracic and pelvic limbs, and feces. Nutrias
have not permanent habitats. In the study we found no evidence of damage on the
environment. The study showed that the result of the vital activity of nutrias
is rather positive, concerning the cleaning of the water areas of vegetation. We
found that the thoracic and pelvic limbs have five fingers. The difference between the volume of the nutria brain
cavity and these of the jackal and fox is provoked by the differences in the
type of their food and lifestyle.
