There are a lot of animals that will seek revenge if wronged, these include great apes, rhesus macaques, elephants, orcas, bottlenose dolphins and magpies.
There are many of examples of animals retaliating for harm imposed on them by people, such as the infamous Siberian Tiger that apparently stalked and killed a hunter.
It's about revenge, a basic animal instinct shared by humans, chimpanzees and even blue-footed boobies.
Yet, Daniel MacNulty, a wildlife-ecology professor at Utah State University asserts in a National Geographic interview that Ottway's assertion that wolves will attack anything that comes near their den, and “are the only animal that will seek revenge.” is “nonsense.”
Dogs don't seek revenge.
Your dog didn't chew, urinate and poop on your favorite shoe because you yelled at her earlier. Dogs aren't spiteful.
Research clearly shows that dogs have the cognitive and emotional capacities to hold grudges. They remember events from the past and these memories can persist for a long while.
Many dogs misbehave in various ways such as being disobedient, damaging furniture, or howling and barking excessively. However, unlike humans, dogs do not understand the consequences of their actions, so regular punishment will be no good.
But simians are not alone; crows, elephants and many other creatures are also known to seek revenge.
Dogs avoid each other after aggressive encounters, whereas wolves rapidly reconcile. (Inside Science) -- Wolves aren't the type to hold a grudge.
Wolves in the wild usually do not pose a threat to humans. Wolves are very cautious animals that generally avoid contact with humans. To put it simply, they are just not interested in humans, as they neither categorise us as prey, nor as conspecifics.
Camels and elephants are also said to hold long-term grudges. One Indian man who left his camel tied up in the heat all day had his head severed from his neck by the animal. There's a lesson there, too: if you're going to mistreat a camel, wear your Cheney mask.
Researchers observed dogs and their owners under several sets of circumstances and discovered that dogs tended to display “guilty” body language more frequently when their owners scolded them than when the owners remained neutral – regardless of whether the dogs had actually done anything wrong.
Hauser, a psychologist and neuroscientist, has argued that non-human animals experience anger and fear, but that shame and guilt are impossible for them since these feelings “depend critically on a sense of self and others,” giving humans “a moral sense that no animal is likely to attain.” In other words, if Ajax wasn' ...
The Hyena – The backstabbing opportunist
They are almost always characterized as being backstabbing opportunists, strolling around to steal the prey of other predators. This impression must be corrected, however, since hyenas are very good hunters and 90% of their prey has been killed by themselves.
Cats never forgive.
Scientists have observed similar behaviors in non-primates like goats and hyenas; the only species that has so far failed to show outward signs of reconciliation are domestic cats.
We think of grief as a uniquely human emotion, but there are many examples of animals apparently experiencing suffering from the loss of a 'loved one'. Recently, off the coast of Vancouver, Canada, a Killer Whale kept her dead calf with her for more than two weeks before finally letting go of the baby's body.
Yelling, throwing sticks or stones, waving your arms, and generally making yourself look as big and scary as possible can deter predatory wolves, which tend to become submissive when other animals demonstrate dominance.
Like many large carnivores, wolves are generally afraid of humans and will avoid people, buildings, and roads if possible.
Wolves are also very aggressive toward domestic dogs. Although encounters between a single wolf and a domestic dog sometimes result in play behavior, encounters between several wolves and a dog usually result in the wolves aggressively attacking the dog.
Jellyfish, starfish, and even corals manage very well without hearts. Starfish do not even have blood, so this explains why no heart is required. Instead, they use small hair-like structures called cilia to push seawater through their bodies and they extract oxygen from the water.
Animals with no natural predators are called apex predators, because they sit at the top (or apex) of the food chain. The list is indefinite, but it includes lions, grizzly bears, crocodiles, giant constrictor snakes, wolves, sharks, electric eels, giant jellyfish, killer whales, polar bears, and arguably, humans.
However, experts have explained why you shouldn't shout at your dog, and that shouting can actually do more harm then good when trying to teach your pup to be well behaved. In fact, not only is it likely to make them naughtier, it can even lead to even stress and depression.
Your pooch needs to be trained with love and compassion. New research suggests that adversely training, e.g. yelling at, your dog could cause long-term psychological harm. Dogs that had undergone adverse training methods were found to have higher cortisol levels in their saliva and displayed more stress behaviors.
