group. Bats Recent studies have determined that vampire bats engage in social grooming much more than other types of bats to promote the well-being of the group. Facing higher levels of parasitic infection, vampire bats engage in cleaning one another as well as sharing food via regurgitation. This activity prevents ongoing infection while also promoting group success. Primates Primates provide perhaps one of the best examples of mutual grooming due to the intensive research performed regarding their varying lifestyles, and the direct variation of means of social grooming across different species. Among primates, social grooming plays a significant role in animal consolation behavior whereby the primates engage in establishing and maintaining alliances through dominance hierarchies, pre-existing coalitions, and for reconciliation after conflicts. Primates groom socially in moments of boredom as well, and the act has been shown to reduce tension and stress. This reduction in stress is often associated with observed periods of relaxed behavior, and primates have been known to fall asleep while receiving grooming. Conflict among primates has been observed by researchers as increasing stress among the group, making mutual grooming very advantageous. There are benefits to initiating grooming. The one that starts the grooming will in return be groomed themselves, getting the benefit of being cleaned. Research has found that primates that are lower on the social ladder may initiate grooming with a higher ranked primate in order to increase their position. Under times of higher conflict and competition, it has been found that this is less likely to occur. Researchers have suggested that primates may see a need to balance the uses of grooming, swapping between its use as a means to increase social standing and the use of grooming to keep oneself clean. Grooming in primates is not only utilized for alliance formation and maintenance, but to exchange resources such as communal food, sex, and hygiene. Wild baboons have been found to utilize social grooming as an activity to remove ticks and other insects from others. In this grooming, the body areas receiving significant attention appear to be the regions where the baboons themselves cannot reach. Grooming activity in these regions is used to remove parasites, dirt, dead skin, as well as tangled fur to help keep the animal's health in good condition despite an individual inability to reach and clean certain areas. Time primates spend grooming increases with group size, but too large of
