At times nature can be cruel, but there is also a raw beauty, and even a certain justice manifested within that cruelty. The alligator, one of the oldest and ultimate predators, normally considered the "apex predator" in it's natural eco-system, can still fall victim to implemented 'team work' strategy, made possible due to the tight knit social structure and "survival of the fittest pack mentality", bred into the canines over the last several hundreds of years by natural selection.

Note that the Alpha dog has a muzzle hold on the gator preventing it from breathing, while the remainder of the pack prevents the beast from rolling.
