, Homosexual parenting is especially present among certain species of birds, one of the most famous examples being Laysan albatross. An example of this is in meadow vole populations. Engagements of sexual activities during non-breeding seasons have been observed in the animal kingdom. They have hands, after all. , Juvenile male chimpanzees have been recorded mounting and copulating with immature chimps. But the researchers say that the monkey in the new study “showed clear sexual behaviour towards several female deer”. , Genital rubbing has been observed once among male orangutans and several times in a small group of lar gibbons, where two males thrust their genitals together, sometimes resulting in ejaculation in one of the partners. Awareness in species is difficult to determine. Our journalists will try to respond by joining the threads when they can to create a true meeting of independent Premium.  Male lions are known for head rubbing, bats engage in licking, and mountain sheep rub horns and faces with each other. , Many birds masturbate by mounting and copulating with tufts of grass, leaves or mounds of earth, and some mammals such as primates and dolphins also rub their genitals against the ground or other surfaces to stimulate themselves.  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. 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.  For example, the lab rat will push the lever because it knows food will fall out of the hole in the wall. Some of those deer tried to escape – but others apparently consented to the behaviour and “accepted the mount”, the researchers write in the journal Primates. ", Homosexual behaviour is found in 6–10% of rams (sheep) and associated with variations in cerebral mass distribution and chemical activity.. But those tend to be seen only between animals that are closely related and look similar, and are understood in the context of their relationship to how they allow the animals’ species to survive. ", 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". The poor victim attempts at some point to peck at its towering assaulter, but with no result. In his 1999 book, Biological exuberance, Bruce Bagemihl documents that: Autoeroticism also occurs widely among animals, both male and female.  Masturbation is common in both mares and stallions, before and after puberty. Through extensive research, scientists have been able to conclude that the brain reward system in animals is extremely similar to that of humans. The existing Open Comments threads will continue to exist for those who do not subscribe to Independent Premium. Insects, spiders, worms, frogs, birds and fish do it, too, Hochkirch said. David Linden, professor of neuroscience at Johns Hopkins University, remarks that: ... perhaps the most creative form of animal masturbation is that of the male bottlenose dolphin, which has been observed to wrap a live, wriggling eel around its penis. Sexual activity in bonobos is very high, yet the rate of reproduction is the same as a chimpanzee. This action was considered as a demonstration of affection and reconciliation.  It sometimes occurs in the Adélie penguin. By signing up to the VICE newsletter you agree to receive electronic communications from VICE that may sometimes include advertisements or sponsored content. , Apes and Monkeys use a variety of objects to masturbate with and even deliberately create implements for sexual stimulation ... often in highly creative ways.. But the ice-clad continent recently revealed a wicked side, when biologists reported that on sub-Antarctic Marion Island, doe-eyed seals are recklessly coercing cute penguins into sex.  All members of the group are potential sex partners, males participate in sexual activity with other males, as do females with other females.  Masturbation occurs more often in primate species with large testes relative to their body size. Besides seals, types of dolphin, bird and big cat have been known to engage in various types of sexual activity with other species. , Among insects, there have been reports of immature females being forcibly copulated with. " The case study earned Moeliker an Ig Nobel Prize in biology, awarded for research that cannot or should not be reproduced. As of 1999, the scientific literature contained reports of homosexual behavior in at least 471 wild species. It does not need awareness, but it does seem to work on a reward system. But even when that happens between similar species, and there is offspring, it usually doesn't perform very well. Compared to the grotesque seal-on-penguin violence that we have been witnessing on Marion Island, that looks like a minor oversight. Females of many species mate with males when they are non-fertile (marmosets for example). The new case is the only the second report of such a case, and apparently the first of this kind. It should be no surprise to anyone that our primate cousins are champion masturbators. Miller, Edward H., Alberto Ponce de León, and Robert L. Delong. , It appears to be common in the Adélie penguin. 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.  It has also been recorded in at least two New World primate species, the squirrel monkey and the spider monkey. More than 70 species of birds engage in one of these two bonding. John Alasdair Macdonald, a tour guide in the Scottish Highlands, caught the meteor on film, on the west shore of Loch Ness. Many studies have concentrated on the brain reward system and how similar it is across mammals. Are you sure you want to mark this comment as inappropriate? They were both killed instantly," Andy Katz, who spotted the clash, wrote, failing to mention that the two had previously been embroiled in a chase through the streets that saw 15 cars and two trucks wrecked and a shoot-out in a nearby park, This stunning image of a shooting star is what award-winning photographs are made of – but the man behind the lens said capturing the sight was an "absolute fluke". It is fairly uncommon among different species for unrelated individuals of the same sex to raise offspring together, but female-female pairings in Laysan albatross populations are one of the exceptions. 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.  There are a variety of acts to show affection such as African elephants intertwining their trunks, giraffes engaging in “necking”, and Hanuman langurs cuddling with each other in a front to back sitting position. He eventually turned to her ten-month-old cub, repeatedly mounting and ejaculating on it. 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. "But here is an animal society that uses homosexuality to improve its social life. 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". The silent, frosty, lonely Antarctic is not a place that usually conjures sex-related thoughts. , Homosexual parenting (sometimes referred to as cooperative breeding) occurs in a wide variety of species in the animal kingdom. exhibit stated that "homosexuality has been observed among 1,500 species, and that in 500 of those it is well documented. 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.
