Resumo
Background: : : : Nutria (Myocastor coypus), also known as Swamp Beaver, is a medium-sized semiaquatic rodent that belongs to the Capromyidae family. Originally from the southernmost part of South America, the species is distributed in several parts worldwide such as Europe and United States, where it has been used for commercial purposes due to the excellent quality of its fur and meat. Information about the nutria morphology is rare. Only a few articles about its abdominal aorta branches can be found, but nothing exists regarding its aortic arch. Consequently, other rodents such as chinchillas, agoutis, guinea pigs capybaras, pacas and rats will be used in the discussion. Therefore, this study aims to obtain morphological information that could justify such discussions in a functional point of view, and that could result in support for a better understanding of the physiology of this animal. Materials, Methods & Results: Thirty-two Myocastor coypus were used in the study, originated from a breeding facility in the town of Caxias do Sul, RS and authorized by IBAMA. The animals were put to sleep by means of an anesthetic overdose administrated intraperitoneally, and kept in formaldehyde for seven days to be subsequently dissected. After having their arterial system flushed with saline solution, the aorta of thirty specimens received an injection containing latex 603 thro
