Abstract

Sexual behavior in animals fulfills reproductive and social functions, extending beyond the traditional focus on reproduction. Same-sex sexual behavior, defined as genital contact or manipulation between individuals of the same sex, occurs in various primate species. In spider monkeys, grappling, a behavior involving prolonged mutual embraces, face greeting, tail intertwining, and genital manipulation, occurs primarily between males. Here, we report a novel incidence of same-sex sexual behavior and grappling between two subadult male brown-headed spider monkeys (Ateles fusciceps fusciceps). Our observation contributes to the understanding of the social functions of sexual behavior and to the broader appreciation of primate sexuality.

棕头蛛猴（Ateles fusciceps fusciceps）在两只亚成年雄猴搏斗时的同性性行为。

动物的性行为具有繁殖和社会功能，超出了传统的繁殖范畴。同性性行为是指同性个体之间的生殖器接触或摆弄，发生在各种灵长类动物身上。在蜘蛛猴中，抓握行为主要发生在雄性之间，这种行为包括长时间的相互拥抱、脸部问候、尾巴交缠和生殖器操作。在这里，我们报告了两只亚成体雄性棕头蛛猴（Ateles fusciceps fusciceps）之间发生的同性性行为和抓握行为。我们的观察有助于理解性行为的社会功能，也有助于更广泛地了解灵长类动物的性行为。

期刊介绍： Primates is an international journal of primatology whose aim is to provide a forum for the elucidation of all aspects of primates. The oldest primatological journal, Primates publishes original papers that advance the scientific study of primates, and its scope embraces work in diverse fields covering biological bases of behavior, socio-ecology, learning and cognition, social processes, systematics, evolution, and medicine. Contributions relevant to conservation of natural populations and welfare of captive primates are welcome. Studies focusing on nonprimate species may be considered if their relevance to primatology is clear. Original Articles as well as Review Articles, News and Perspectives, and Book Reviews are included. All manuscripts received are initially screened for suitability by members of the Editorial Board, taking into account style and ethical issues, leading to a swift decision about whether to send the manuscript for external review.
