同类相食是动物中相当常见的行为，在食物稀缺或人口过剩的情况下具有生存价值。相反，同类相食也会增加病原体传播并降低健康水平。在灵长类动物中，某些同类相食的情况与杀婴有关，或者是母亲在新生儿死亡后进行的（孝顺同类相食）。我们在此报告了在半自由放养的棕色卷尾猴（Sapajus apella）群体中首次观察到的同类相食现象，特别是婴儿同类相食现象。婴儿很可能是死产，因为部分颅骨缺失，并且没有可见的新伤。母亲在照顾死婴半天后，吃掉了尸体的部分皮肤和营养丰富的内脏，可能是为了补偿怀孕所付出的生理代价。死婴的哥哥在仔细观察母亲的行为后，也同样吃了尸体的一部分。尽管我们不能排除特质和垂直社会传播，但同类相食可能是卷尾猴行为的正常组成部分，尽管这种情况很少见。
Cannibalism is a quite common behaviour in animals that can have survival value when food is scarce or in the case of overpopulation. Conversely, cannibalism can also increase pathogen transmission and reduce fitness. In primates, some cases of cannibalism are associated with infanticide or are performed by mothers after their newborn has died (filial cannibalism). We report here the first observation of cannibalism, specifically infant cannibalism, in a semi-free-ranging group of brown capuchin monkeys (Sapajus apella). The baby was likely stillborn, as parts of the cranial bones were missing and no fresh injuries were visible. After half a day of taking care of the dead infant, the mother ate part of the corpse’s skin and the highly nutritional viscera, possibly thereby compensating for the physiological costs of pregnancy. After attentively watching his mother’s behaviour, the older brother of the dead newborn similarly ate parts of the corpse. Although we cannot rule out idiosyncrasy and vertical social transmission, it is possible that cannibalism is a normal—albeit rare—part of the behavioural repertoire of capuchin monkeys.
