![]() In this report, we contribute a novel observation of same-sex fellatio occurring among two sanctuary-living adult male chimpanzees occurring during a period of social tension. Furthermore, two published reports in chimpanzees also documented oral-genital contact between juveniles in the context of play, however they do not specify whether fellatio was observed (Savage & Malick, 1977 Savage-Rumbaugh & Wilkerson, 1978). Thus far, it has been reported between male-male dyads of laboratory-housed stumptailed macaques ( Macaca arctoides Chevalier-Skolnikoff, 1974) and during periods of crowding among male Tibetan macaques ( Macaca thibetana), with the author suggesting it to play a role in greeting and tension reduction (Ogawa, 2006). Genital contacts also occur in chimpanzee conflict contexts although they are no more common than kissing, embracing, and submissive gestures (de Waal & van Roosmalen, 1979).ĭespite the prevalence of sexual behaviours in primates, fellatio - whereby a partner’s penis is taken into another’s mouth - appears to be rare. Compared to bonobos, same-sex sexual behaviour is rare in chimpanzees, although males in the wild regularly share body contacts, including genital touches and mounting, prior to events that benefit from cooperation and group cohesiveness, such as intergroup encounters (Wittig et al., 2016 Samuni et al., 2019). Although same-sex sexual behaviours can occur in a range of contexts in animal taxa, in both chimpanzees and bonobos, these behaviours are especially common during socially tense periods including pre-feeding, post-conflict periods, inter-group encounters, and, for chimpanzees, before boundary patrols (Paoli et al., 2007 Wilson et al., 2007 Herbinger et al., 2009 Clay & de Waal, 2015 Wittig et al., 2016 Samuni et al., 2019, see supplementary material). Pan same-sex sexual behaviours include mounting, genital touching, and rump-rump touching (de Waal, 1988 Goodall, 1989). Nevertheless, as has been suggested for same-sex mounting among female Japanese macaques (Vasey, 2006), same-sex sexual behaviours do not always appear to convey an adaptive benefit.Īlthough same-sex sexual behaviour is habitual and particularly pronounced among bonobos (de Waal, 1990), chimpanzees ( Pan troglodytes) are also know to engage in same-sex sexual behaviour across multiple contexts (Savage-Rumbaugh & Wilkerson, 1978). Among our close relatives, the nonhuman primates, proposed functions include promoting cooperation and coalitionary support as well as preventing and reducing social tension, such as through post-conflict reconciliation (Vasey, 1996 Paoli et al., 2007 Clay & de Waal, 2013 Moscovice et al., 2019). ![]() A varied and widespread behaviour in the natural world, homosexual or same-sex sexual behaviour may have diverse as well as species-specific functions (Hanby, 1976 Moscovice et al., 2019), and, in some cases, represent idiosyncratic innovations for behaviourally flexible animals. ![]() DIMENSIONS (single pot feet): H9 x W6.5 x D9.Same-sex sexual interactions, i.e., genital contacts, mounting or other sexual solicitations between same-sex partners have been documented in many animal taxa including mammals, birds, marine life, and insects (Sommer & Vasey, 2006 Bailey & Zuk, 2009).The packaging can be onward recycled once discarded. They are also safely encased within a foam protection layer (also 100% recycled), making breakages in transit highly unlikely. Please see photos of the type of pots we suggest work best with this design.Įach set of 3 Potty Feet come beautifully packaged using 100% recycled and certified materials in our own custom designed and branded gift boxes, making this an ideal and unique gift for loved ones and friends. The Chimpanzee can adjust to suit any width of pot, and our Potty Feet can take any weight of pot or planter!! Our Potty Feet are designed to fit most shapes of pot, although we cannot guarantee that they will fit every design. The Chimpanzee comes in a set of 3 so that your plant pot stands evenly balanced on any surface - whether in your home or outside, and displayed beautifully on your decking or patio. Our award-winning Chimpanzee Potty Feet have been custom designed and manufactured by Jardinopia Ltd, and are made from a unique formula of crushed stone and durable poly resin, making them frost proof and UVA resistant - so they can be safely used outside or indoors throughout the year!
