INTRODUCTION.Placentophagy is the consumption by peripartum females of all or some placental components soon after giving birth(Kristal 1980).It is a widespread behavior across eutherian mammals with the exception of cetaceans and domesticated camelids(Kristal 1980;Vaughan&Tibary 2006).Another notable exception is in humans but is a culturally determined practice due to health benefits(Farr et al.2018)and traditional medicine(Ober 1979).In nonhuman primates,placentophagy has been recorded across diverse taxa—from great apes(chimpanzee,e.g.Goodall&Athumani 1980;Fujisawa et al.2016,bonobo,Douglas 2014,gorilla,Stewart 1984,and orangutan,Galdikas 1982),gibbons(Hylobatidae)(Hayssen et al.2019),old world monkeys(Cercopithecidae)(Turner et al.2010;Yao et al.2012;Ding et al.2013)to new world monkeys(Callitrichidae,Hayssen et al.
