Myocaster coypus
The coypu or nutria (Myocastor coypus) is a large, crepuscular, semiaquatic rodent native to South America, but now also present in Europe, Asia, and North America. In most regions, the coypu is considered a pest. However in eastern Europe and Central Asia, it is still valued for its fur. It is the only species in the genus Myocastor and is sometimes given its own family: Myocastoridae. The coypu, an herbivore, has been introduced from South America to every continent except Australia and Antarctica. Africa is the only continent where the introduced coypu never became fully established. The animal is adapted to subtropical to mild temperate climates.
There are two common names used in the English language for Myocastor coypus. Coypus originated from the Amerindian Araucanian language word coypu or kóypu and was adopted by American Spanish as Coipo is generally used in Europe and Latin America. This avoids confusion with the term "nutria," which is Spanish for carnivores commonly called otters (Lutra sp.) in British and American English. In North America and Asia, the term nutria is the more commonly used one for Myocastor coypus.
The coypu somewhat resembles a very large rat in appearance. Adults are typically 5–9 kg (10-20 lbs) in weight, and 40–60 cm (15-24 in) in body length, with a 30–45 cm (12-18 in) tail. They can also be identified by their bright orange-yellow incisor teeth (unlike rats, which have brownish yellow incisors). The nipples of female coypu are on their back. This allows their young to feed while the female is in the water.
Coypu can also be mistaken for another widely dispersed semi-aquatic rodent that occupies the same wetland habitats, the muskrat. However, the muskrat is smaller, more tolerant of cold climates, and has a dorso/ventrally flattened tail that it uses to assist in swimming, whereas the tail of a coypu is round.
The distribution of coypu tends to expand and contract with successive cold or mild winters. During cold winters, coypu often suffer frostbite on their tails leading to infection or death. Populations of coypu under these circumstances often contract and even become locally or regionally extinct (as in the Scandinavian countries during the 1980s). During mild winters, their ranges tend to expand northward

I saw some of these swimming in a lake in Italy and have some video footage of them playing on the banks. I never saw one so close up. Wonderful details and a nice composition

Una retrato de gran belleza y calidad. Me gusta la pose de la nutria que parece estar atenta a sus cosas. Un saludo

Bonito primer plano Paula con gran agudeza, mostrando muy buenos detalles del mamífero.
Me gusta el punto de vista captado y el encuadre elegido, saliendo el animal desde un vértice de la imagen.
Excelente control de la iluminación y foco a pesar de la escasa velocidad de la captura.
Sólo criticaría un ligero ruido de fondo, seguramente como consecuencia del uso de ISO800.
Gran presentación... gracias por compartirla.
Un cordial saludo desde Buenos Aires... Ricardo

Beautiful close up Paula with great sharpness, showing very good details of the mammal.
I like the captured point of view and the elected framing, going out the animal from a vertex of the image.
Excellent control of the illumination and focus in spite of the low speed of the capture.
Only I would criticize a slight bottom noise, surely as consequence of the use of ISO800.
Great presentation... thank you for sharing.
A cordial greeting from Buenos Aires... Ricardo
