Abstract
ABSTRACT In view of the scarcity of data about the topography and syntopy of abdominopelvic viscera of the giant anteater (Myrmecophage tridactyla - Linnaeus, 1758), the present study aimed to elucidate these characteristics and to compare them with the other animal species, especially the domestic ones. Three specimens, two males and one female, were donated by the Environmental Military Police of Franca to the Anatomy Veterinary Laboratory of the University of Franca, after death by road killings. The animals were fixed and maintained in aqueous 10% formaldehyde solution, followed by conventional dissection of the abdominopelvic cavities for subsequent direct inspection and topographic description of the viscera, aiming at comparative analyzes with other species, whose positioning and particularities are already established in the literature. It was observed that most of the viscera of these cavities have similar location and syntopy to domestic animals, except for the kidneys and testicles. In view of the established methodology and the results obtained, it is accepted that more specimens of anteater, both genera, should be evaluated and registered scientifically to confirm the data of the current research and anatomical preconization of the abdominopelvic cavity, inasmuch anatomical individual variation are possible between animals of the same species.
Highlights
The giant anteater (Myrmecophage tridactyla Linnaeus, 1758), representative of the suborder Xenarthra and the Pilosa order, it is the largest representative of the Myrmecophagidae Family (Miretzki and Braga, 2014), being found in Southeast Mexico, Central and South America (Ribeiro et al, 2013, Ribeiro et al, 2016), in some areas is in extinction (Braga, 2004; Miretzki and Braga, 2014) as a result of environmental destruction such as fires, predatory action by man, illegal traffic and automobile acidentes, besides reproductive and alimentary factors (Medri and Mourão, 2005; Giraldi et al, 2017)
Considering the importance of the organs that compose the abdominopelvic cavity and the constant interest in the creation and preservation of wild animals, the present research had the objective of describing the topography and syntopy of these, since in these giant anteaters, these data are spare in the scientific literature and notwithstanding, to compare them with animal species
Due to the constant interest in the creation and preservation of wild animals, the study of topographic anatomy becomes essential to clarify both the behavioral and evolutionary data of these species (Sesoko et al, 2015; Giraldi et al, 2017), the objective was to describe the comparative morphology and syntopy between the organs that compose the abdominopelvic cavity of the giant anteater, comparing them with the domestic animals
