According to legend, it is slow but ferocious and very dangerous due to its ability to move without noise in the thick vegetation, surprising the unsuspecting locals. Accounts state that it gave off a putrid stench and emitted a frightening shriek, and that weapons such as arrows and bullets could not penetrate the Mapinguari’s alligator-like hide. Its only known weakness is that it avoids bodies of water, which limits its movements in a region where so many rivers, brooklets and lagoons exist (especially during the rainy season). It was believed to be carnivorous, as a 1937 report from central Brazil claimed a mapinguari had gone on a three-week rampage, killing over 100 cows and ripping out the tongues from their carcasses. However, in all accounts it did not eat humans, although when it smells the presence of people it stands up on its back feet, becoming as tall as two metres, a movement similar to grizzly bears.
