The discovery has prompted a lot of marveling from the media. There are numerous documented instances of animal masturbation , a habit enjoyed by primates as well as creatures including dolphins, elephants, penguins, and bats. Although the role of the sika deer adds a layer of complexity: Can a deer consent to interspecies frottage? That matter aside, there are a lot of animals out there who are, if you will, spanking the monkey. So if macaques do it, dolphins do it, birds and probably even bees do it, why do humans still have so much difficulty talking about sexual pleasure? Sex education curricula rarely venture beyond discussions of condoms, birth control, and puberty if they even cover condoms and birth control ; for many of us, the idea of discussing masturbation seems particularly prurient and unseemly. Not that I necessarily want to hear a member of the Trump Administration talking about double-clicking the mouse.
By Michael Marshall. Supposedly, if women live together their hormonal cycles start to synchronise, thanks to a pheromone. If that were true it would mean that they all have their period simultaneously. Just think about it. But it may not really exist. Studies have had mixed results , often reporting no synchrony at all. Assamese macaques live in troupes of a few dozen, including about a dozen adults of each sex, plus offspring.

The wild monkeys were observed mounting the deer in Minoo, central Japan. Similar monkey-deer interactions on Yakushima Island were reported in January But while the previous research is based on anecdotal evidence, the current work focuses on the numbers. According to the team, which also consists of researchers Paul Vasey and Jean-Baptiste Leca , this paper is the first quantitative study of sexual interactions between a non-human primate and a non-primate species. Wild Japanese macaques have long been known to ride sika deer. The monkeys will sometimes groom their four-legged mounts, while the deer get to eat any fruits the macaques drop and occasionally make meals of the monkeys' feces.
