Alligator Gar (episode)[]
Jeremy Wade determined that this species was the perpetrator behind a grizzly attack on a little girl which was blamed on an Alligator Gar, a large predatory fish. While Alligator Gar are also large predators, their thin snouts are much better suited to attacking fish than large animals such as humans. Therefore, almost all attacks blamed on Gar are attributable to Alligators.
Description[]
American Alligators can grow up to 15 feet in length and 999 pounds in weight. They have thick, robust jaws, which make them excellent at dragging down large prey such as deer, although, they normally feed on smaller animals such as amphibians and small mammals and reptiles.
