Based on this information, this study was conducted to describe the collateral arteries of the aortic arch of Antillean manatee and define the standard model for the species. Three specimens, an adult male, adult female and a male neonate, all strandings on the coast of the state of Rio Grande do Norte, Brazil, were used. The study was performed in the Laboratory of Morphophysiology of Vertebrates of the Federal University of Rio Grande do Norte, where in situ photographs were taken to demonstrate their topography. Subsequently, their hearts were removed and fixed in 10% formaldehyde and after 72 hr were dissected and analysed, obtaining schematic drawings and photographs of the vascular arrangement. The aortic arch was represented by three collateral arteries identified as the brachiocephalic trunk, left common carotid artery and left subclavian artery. This arrangement was similar to that found for other sirenians, and yet, for other mammals like hooded seal, murine, margarita island capuchin, black-handed tamarin, Mongolian gerbil and human. The morphological similarity presented in this study with different species of mammals, including humans, may contribute valuable information from an evolutionary point of view.Item AMAZONIAN MANATEES (Trichechus inunguis) INHABITING AN EQUATORIAL METROPOLIS: HISTORICAL RECORDS AND MATING ACTIVITY NEAR BELÉM, NORTHERN BRAZIL(2021-12-22) Emin-Lima, Renata; Costa, Alexandra Fernandes; Attademo, Fernanda Löffler Niemeyer; Hauser-Davis, Rachel Ann; Luna, Fábia de Oliveira; Siciliano, SalvatoreThe West Indian manatee Trichechus manatus Linnaeus, 1758 and the Amazonian manatee T. inunguis (Natterer, 1883) occur in the Marajó Bay area and in the inlets and channels near Belém. The Amazon Aquatic Mammal Study Group (GEMAM) coordinates a collaborative network for trapped and rescued manatees along the coast of the state of Pará and in the interior of Belém. The presence of the Amazonian manatee is confirmed with the rescue and sightings in the great Belém area. The samples of these manatees are housed in collections of institutions such as MPEG and ICMBio, CMA. On October 31st 2021, Amazonian manatees were sighted swimming near a beach in the Mosqueiro district, in greater Belém. Residents and tourists took images that show a mating behavior reported in the literature for Trichechus spp. The waters in this area are turbid and these records are a significant opportunity to understand this behavior. The event may suggest that Amazonian manatees are returning to the Belém area and its surroundings, as well as to the east coast of the state of Pará, possibly due to the synergic effects of SARS-CoV-2, providing areas less disturbed by humans, pandemic and the current climate change scenario, which would be a hope for this endangered species.
