Well, I quickly learned how vicious a racoon can be when the dominant male got angry at one of the younger males. It was almost like he was a different animal.
Arella Mae, What you're describing is not at all viciousness. For animals in which there is an alpha (male and/or female), the alpha will always assert itself. It's the way the order of the group is maintained and the way the other animals can learn and be a part of the group.
In the case you're describing, the younger male overstepped his bounds. The alpha has dibs on all food and all food choices. Don't be pushy with the alpha. EVER!
This principle applies to lions, chimps, meerkats, wild canids, hippos, elephants, monkeys, gorillas, and on and on.
Have you ever seen wild chimps on a hunt? I've seen films of this. Our very closest relatives are very impressive, intelligent, and successful hunters. They hunt and eat monkeys. The alpha leads the charge and gets the goodies. Sometimes it will share with associates.
Chimps have also been known to be at war (territorial issues) with other troops. They will fight to the death. Vicious? Or instinctive?
I do not believe that there is anything "vicious" in the natural world. If a dog is "vicious," it's likely the result of human action.
At this point, I'm guessing that you know that I think there is only one truly vicious animal on the planet. Us.
