Viperwolf

The viperwolf (Na'vi name: nantang) is a small, hyena/wolf-like carnivore that has six legs, a lean, powerful torso and has evolved to travel swiftly over long distances in search of prey. Very few predators (the mountain banshee among them) will attempt an attack on a viperwolf. Viperwolves almost always move in packs that can mass together into a highly cooperative hunting party within seconds of finding prey. A pack of viperwolves attack Jake Sully when he becomes lost in the jungle during the night. He makes attempts to fend them off with a torch and manages to injure two viperwolves before a third leaps on him and pins him to the ground. Neytiri intervenes and saves his life by killing that viperwolf and two others, before driving the rest of them away. Viperwolves, called into battle by Eywa, attack SecOps mercenaries toward the end of the Assault on the Tree of Souls. They are also featured in the game, when a group of them attack the Landing Zone in the Blue Lagoon.
