Testudinidae Knowledge about turtles of the Brazilian Amazon has been accumulating, thanks to continued efforts of the research institutions and governmental organs engaged in environmental management and conservation of species, especially those of economic interest, practice fundamental to the maintenance of wild populations, as opposed to strong pressure from hunting and collecting eggs. Currently 16 turtles species are known for the Brazilian Amazon. Of these, eight are in the red list of endangered species in the IUCN categories vulnerable (5), low risk (2) and in danger (1). Here we present the characterization of turtle fauna of the Viruá National Park, located in the Municipality of Caracaraí, state of Roraima, Brazil. We carried out two expeditions, one during the rain season, and another during the dry season. The methods of capture were trammel nets, fike nets, Legler traps and visual enccounter. The study covered the wide variety of environmental physiognomies, and sampled areas of igapó, streams, rivers, semi permanent flooded land and dry land. Nine species have been recorded, belonging to five families. The species most frequently recorded was Podocnemis erythrocephala (n = 38), popularly known as irapuca, captured only in black-water river. The species Chelus fimbriatus (matamatá), generally considered rare or difficult to detect was caught with frequency (n = 22) in almost all the sampling points. Podocnemis expansa (n = 4) was probably under-sampled apparently because the methods used to catch are not efficient for that species. The other species recorded were Podocnemis sextuberculata (n = 33), Podocnemis unifilis (n = 25), Platemys platycephala (n = 1), Rhinoclemmys punctularia (n = 1), Geochelone carbonaria (n = 3) and Geochelone denticulata (n = 2). The results show the importance of the implementation of conservation units as a measure of protection to turtles of the Amazon, by alleviating the pressure of human hunting and predation of nests.
