Description Of The Coypu (Myocastor Coypus) 1724 Words 7 Pages INTRODUCTION: The Coypu (Myocastor coypus) is a large, robust, semi-aquatic rat like rodent and a casual observer may misidentify a Coypu as a beaver or a muskrat, especially when it is swimming.

Myocastorini is a tribe of echimyid rodents, proposed in 2017, and containing the five extant genera Callistomys, Hoplomys, Myocastor, Proechimys, and Thrichomys.

Myocastor coypus (Molina, 1782) is a large, herbivorous, semiaquatic rodent. The coypu lives in burrows alongside stretches of water, and feeds on river plant stems. Originally native to subtropical and temperate South America, it has since been introduced to North America, Europe, Asia, and Africa, primarily by fur farmers (Wikipedia contributors 2019).

Measurements (mm) - Maximum Lenght: 114.4, Zygomatic Breadth: 67.0, Posterior Cranial Breadth: 52.5, Nasion-Basion: 67.4.

Nutria, (Myocastor coypus), a large amphibious South American rodent with webbed hind feet. The nutria has a robust body, short limbs, small eyes and ears, long whiskers, and a cylindrical, scaly tail. It can weigh up to 17 kg (37.5 pounds), although 5 to 10 kg is usual; the body measures up to 70.

We created a model to study the process in which nutria (Myocastor coypus) feeding activities lead to erosion and loss of marsh area. This model ties together data on nutria population dynamics and feeding behavior from the literature with data from field studies on the phenology of Scirpus americanus and Spartina patens conducted in the Barataria Basin, Louisiana, USA in 1992.

The coypu (or nutria, Myocastor coypus) is a large, plant-eating, rodent which lives in wetlands.The nutria first came from South America including Argentina, Bolivia, Brazil, Paraguay, Chile, and Uruguay.Animals were taken to Louisiana in the 1930s to be farmed for their fur. Some of these animals escaped and are now living in the Louisiana coastal wetlands.

The objective of this study focused on the comparative morphological and histochemical analysis of the duodenum of fetuses, juveniles and adult coypu (Myocastor coypus bonariensis), the major socioeconomic wildlife resource of Argentina. Histological and histochemical procedures for in situ characterization of glycoconjugates (GCs) were used.

Sixteen nutria (Myocastor coypus) from a protected area in Curitiba, Brazil, were sampled to determine the prevalence of Fasciola hepatica eggs and intestinal parasites and the presence of snails in the habitat used by nutria. The overall prevalence rates were 56.25% (9) for F. hepatica eggs, 87.50% (14) for cestode eggs, 56.25% (9) for ascarid eggs, 50% (8) for coccidian (Eimeriidae) oocysts.

The aim of the present study was to examine the histology of the cervix of coypu. Samples from mature sexually animals were used. Tissue was processed by routine histological techniques. The histological stains used were Mayer's hematoxylin and eosin, Masson's trichrome stain, PAS and picrosirius-red. The exocervical mucosa showed squamous stratified epithelium and the lamina propria consisted.
