The researchers found that nearly a third of potential interactions resolved when one group simply avoided the other entirely. But when things did escalated into a feud, the meerkats generally displayed some kind of chasing or dancing behavior as a prelude to the actual violence. The Jets and the Sharks could learn a thing or two: A meerkat war dance is quite effective at deterring a battle. Some 86 percent of all aggressive interactions ended before the fighting ever began. Meerkats didn’t kill one another most of the time, but at least one death occurred in 13 cases, adding up to 22 total fatalities. Most upsetting of all, 20 of those were pups.
