", After studying bonobos for his book Bonobo: The Forgotten Ape, primatologist Frans de Waal, a professor of psychology at Emory University in Atlanta, says that such expressions of intimacy are consistent with the homosexual behaviour of what he terms "the erotic champions of the world". [37] Attempting to inhibit or punish masturbation, for example by tying a brush to the area of the flank underside where the penis rubs into contact with the underside, which is still a common practice of horse managers regionally around the world, often leads to increased masturbation and disturbances of normal breeding behaviour.[38]. [83], Necrophilia describes when an animal engages in a sexual act with a dead animal. The scientists say that the most likely explanation for the strange behaviour is “mate deprivation”, a theory that suggests that animals that don’t have access to females are more likely to show such behaviour. Researchers recently caught seals trying to get it on with penguins. Most of those examples also constitute a kind of sexual harassment. Because animals possess a brain reward system they are motivated to perform in different ways by desire and reinforced by pleasure. Marine mammal science 12.3 (1996): 468-476. [77] This is a natural part of their reproductive biology – they have a delayed gestation period, so these females give birth the following year when they are fully grown. This organ is present in the females of all mammalian species and several other animal groups. [16], Anal penetration with the penis (both in heterosexual and male homosexual dyads) has been observed among some primate species. [68] Nevertheless, animals in the wild have been observed to attempt sexual activity with other species. In it, a male fur seal forcibly humps a hapless king penguin, while other penguins cowardly stay at arm's length from the odd couple. The most insightful comments on all subjects will be published daily in dedicated articles. Are you sure you want to delete this comment? [71], A 2008 review of the literature found 44 species pairs that had been observed attempting interspecies mating, and 46 species pairs that had completed interspecies matings, not counting cases that had resulted in hybridization. Bonobos are one species notoriously known for using sexual behavior to relieve their aggression with each other. The success of reproduction for each individual lion is dependent on the number of male lions found in their social group. It’s also unlikely that they would have sex with them because they were short of a mate – since in that case they tend either to masturbate or show homosexual behaviour. Male homosexual anal penetration has been recorded in Old World primate species, including gorillas, orangutans, and some members of the Macaca genus (namely, stumptail, rhesus, and Japanese macaques). [11], In a case study, female Japanese macaques were studied to find evidence of possible female copulatory orgasms. Miller, Edward H., Alberto Ponce de León, and Robert L. Delong. Researchers observed that the longer and higher number of pelvic thrusts, the longer copulation lasted. The term GG rubbing is frequently used by primatologists to describe this type of sexual intimacy among female bonobos, and is stated to be the "bonobo's most typical sexual pattern, undocumented in any other primate". But the scientists hope that further study of it can show how mating happens between species, and could also shed light on why humans show a sexual interest in animals. [58][59], Male-male copulation has been observed in captive penguins[60] and homosexual behaviour has been observed among bats, in particular, the fruit bat. [10], Recent studies using positron emission tomography (PET) and magnetic resonance imaging (MRI) has provided evidence proving that chemical changes that occur with emotions are similar between humans and non-human animals. The male will not demonstrate any form of aggression towards the female.[3]. They have hands, after all. "Humans have created the myth that sexuality can be justified only by reproduction, which by definition limits it to hetero sex," says Michael Bronski, author of The Pleasure Principle: Culture, Backlash, and the Struggle for Gay Freedom. "A lion and a tiger breed only if you put them together in the same cage, and it usually happens because the male has no idea of how a female of his species should look like," Kuijper told me. The whole footage is disturbing and eerily surreal. There are several techniques, in which animals engage in masturbation from using paws, feet, flippers, tails, and sometimes using objects like sticks, pebbles, and leaves. The cub sometimes ignored this and sometimes struggled "slightly as if in play". When they engage in these actions with other species it's like if they're saying 'I'm in charge, I'm dominant over you,'" Staniland said. Usually, reproductive interference is thought to be the result of one animal not properly recognising what species another animal is. [74] Inter-species sexual behavior has also been observed in sea lions. As anglerfish live in the deep sea, they are very rarely seen in their natural habitat, and fewer than half a dozen have ever been captured on film or video in the wild, according to experts at the Monterrey Bay Acquarium Research Institute (MBARI), Dave Pearce’s photograph is the first confirmed sighting of a wild English pine marten in a century. Here, "misdirected mating" is typically the result of strong similarities between the species, which just end up mating and having children. Male bighorn sheep are divisible into two kinds: the typical males among whom homosexual behaviour, including intercourse, is common and "effeminate sheep", or "behavioural transvestites", which are not known to engage in homosexual behaviour. [9], Homosexual parenting (sometimes referred to as cooperative breeding) occurs in a wide variety of species in the animal kingdom. Sexual activity in bonobos is very high, yet the rate of reproduction is the same as a chimpanzee. [4] Primates also engage in kissing that is incredibly similar to human display of kissing. More about Deer [80], Among insects, there have been reports of immature females being forcibly copulated with. Want an ad-free experience?Subscribe to Independent Premium. Researchers stated that after primates participated in a heated, physical fight; both primates involved in the fight would hug and have a mouth-to-mouth kiss. [78][79], It appears to be common in the Adélie penguin. If a smooth pebble is introduced into the hutch, she will masturbate upon it, thus preserving her normal health for one season. [9][15] Another form of genital stimulation is masturbation. [22], A case of male homosexual anal penetration with the finger has also reported among orangutans,[23] and Bruce Bagemihl mentions it as one of the homosexual practices recorded at least once among male chimpanzees. [40], Apes and Monkeys use a variety of objects to masturbate with and even deliberately create implements for sexual stimulation ... often in highly creative ways.[40]. But as he clicked away, the meteor soared right into his  sights, A unique photograph has been taken of a bird with a visible egg showing after experts sent to study a critically endangered Mascarene Petrel on a remote Indian Ocean tropical island encountered an undeniably pregnant member of the species, Researchers in the US have released what they believe to be the first video footage showing a bizarre-looking Black Sea Devil anglerfish in the wild. Successful coalitions have usually created a strong bond with each other and will take over prides. [80] Homosexual necrophilia has been reported between two male mallard ducks. Most were known from laboratory experiments, but field observations had also been made. Just after I switched from my binoculars to my camera the bird flew across me and slightly in my direction; suddenly it was obvious it had a small mammal on its back and this was a struggle for life", "This bumblebee was impaled by this hummingbird. While in search for another pride these males will often engage in sexual behavior with each other; creating a strong bond in this new coalition created. The researchers wrote that one deer "seemed to accept to be ridden by the male macaque", and that it was apparently licking sperm that had been deposited on its back by the monkey. [2] There have also been observations of animals engaging in homosexual behaviors,[3][4] as well as sex with dead animals[5] and sex involving juveniles.
