In the photo on the right, he uses his right hand to hold the monkey down, and consumes muscle from the inner thigh of the right hind leg. In the photo on the left, he holds the carcass in his left hand, and sucks the brain from the skull. Screen captures show videotaped meat-eating by an adult male chimpanzee in the Kasakela community at Gombe National Park, Tanzania. "Twice, we observed the possessor sucking on the head, presumably extracting the brain," the scientists wrote. Whenever a chimp caught a young monkey, they all typically used a similar method to kill and eat them, biting down on the head and pulling hard, "apparently trying to remove the body from the skull," according to the study. For adult monkeys, the chimps also were interested in the brains, but they cracked the skulls first only 44 percent of the time. Prior research suggested that chimps found monkey brains to be especially desirable the scientists cited a chimpanzee study from 1973 that noted, "The brain is the only organ for which marked preference is regularly shown, and the eating of brain tissue is always a slow, meticulous procedure with a definite undertone of enjoyment."įor the new study, the team recorded 29 incidents of monkey-eating by eight chimpanzees, and found that if the monkey was a juvenile, the chimps first went for the head 91 percent of the time. They also contain certain fatty acids that are absent from plants and are known, at least in humans, to be important for brain function and for lessening the damage from some diseases, the study authors reported. Brains, especially mammal brains, are especially high in fat.
