Adults can reach nearly 1.8 m in total length, and 30 kg in weight, with males slightly larger than females (DUPLAIX, 1980). They are a part of the animal family Mustelid. Since their diet is mainly piscivorous, giant river otters may change areas, following seasonal fish migrations (DUPLAIX, 1980). Endemic to South America, the giant river otter is restricted to aquatic ecosystems in tropical forests and wetlands up to 300 m a.s.l. They are often mistaken for beavers though. The highest incidence of negative interactions occurred near areas occupied by humans either close to community organizations, where there is higher human population density, or in the vicinity of isolated residences located in igarapés upstream of the Amanã Lake (Figures 2 and 3).
