Throwing a right hook as he launches onto his opponent with his gnarling teeth at the ready, this is the OTTER-LY ruthless showdown between two otters. The otter takes no prisoners and packs a mean punch as he battles it out with a rival in a war over food and terrority. The clash is captured in great detail and shows the feisty otter raising his arm and swinging for his opponent, who falls back into the water from the force of the knockout Haymaker-style jab to the face. In one picture, you can see his piercing teeth as he prepares to take a razor sharp chunk out of his helpless competitor.
