Indeed, studies have shown that chimpanzees and macaques not only seek revenge, but often do so intelligently — for instance, if they see that their adversary is stronger than them, they attack a weaker relative instead.
First, they confirmed that monkeys that find themselves at the receiving end of aggression tend to turn around and take it out on a third party. And that retaliation is often directed at a relative of the original aggressor.
The studies presented here suggest that chimpanzees are vengeful but not spiteful. Chimpanzees are retaliatory, in that they are negatively reciprocal (34), at least on a very short time scale, consistent with retribution as a means of discipline in animal societies (2, 22–24).
Yes, animals do practice revenge. Chimps do it, for example. Macaques do it, too, although not directly: if they cannot attack the offender because he is much stronger, they would hurt someone weaker instead, sometimes the attacker's relative.
Monkeys, like humans, will take the time and effort to punish others who get more than their fair share, according to a study conducted at Yale. In fact, they can act downright spiteful.

Monkeys to feel regret and learn from their mistakes just like humans, according to a new study.
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.
According to another a study published in the journal Animal Behaviour, ravens which include crows, jays and magpies, have the ability to 'hold grudges' for up to two years.
No. They kill to survive. This is not something that can have guilt ascribed to it. It is a necessity.
These found chimpanzees show affection and compassion, grieve for dead babies, hold grudges, use and make tools, develop lifelong friendships and display “Machiavellian intelligence” (political and social skills like deception and creating alliances).
The researchers found that the chimpanzees were more likely to collapse the table when they were aroused than when they were calm. Moreover, they were most likely to get upset when they were the victims of theft by other chimpanzees. The authors suggest that the chimpanzees' punitive behavior was motivated by anger.
It's likely that primates are especially violent because we are both territorial and social—two factors that respectively provide motive and opportunity for murder.
Myth: Chimps can smile like humans do.
Chimps make this expression when they are afraid, unsure, stressed, or wanting to appear submissive to a more dominant troop member.
If a macaque makes a surprised-looking face with an open mouth, wide eyes, and raised eyebrows, it's angry at you and warning you to back off. If it leans forward toward you while doing this, it's an outright threat; the next step is to run toward you and try to chase you away.
Sadly, many tourists misread wild monkey facial expressions. A wild monkey which appears to be smiling, pouting its lips or baring its teeth is not friendly. Many tourists mistakenly think that the monkey is smiling or blowing a kiss. Nothing could be further from the truth as these are all signs of aggression.
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.
Whether or not it is possible to “die of a broken” heart, one thing is without question: “We humans don't own love or grief – these emotions are widespread in other animals,” says Dr Barbara J King, Emerita Professor of Anthropology at the College of William and Mary, and author of How Animals Grieve .
Why tardigrades are so damn tough. It's important to note: Tardigrades are basically indestructible only when they enter a special state called cryptobiosis. In harsh environments, the animals tuck in their legs and expel all moisture from their bodies. In this state, they're called tuns.
Camels are symbols meaning humility, willingness to serve and stubbornness. In medieval art and sculpture, the camel was used to represent humility and the willingness to bear another's burden; largely because camels are trained to kneel down to receive heavy loads.
Monkeys are scared of snakes. Keep real looking plastic snakes at roof tops or boundary wall of your house. Loud heavy noise, bursting of crackers or their sound track will force the monkeys to leave any premises. An injured monkey should be helped when monkey group is not close by.
Researchers investigated jealousy in male titi monkeys – a monogamous primate that shows jealousy much like humans. Jealousy leads to increased brain activity in areas associated with social pain and pair bonding in monogamous monkeys, finds a study in Frontiers in Ecology and Evolution.
Monkeys, apes and other simians have nothing quite like our tears. They have tear ducts to help keep their eyes lubricated and clean. But they don't drain when they're sad. Chimps will scrunch up their faces and make noise when they're in distress, but they don't connect the tears and the wailing.
