Humans and dolphins are the only animals that have sex for pleasure.  Oh, and monkeys too I guess.

There are many different types of "sex" practiced in the plant and animal kingdoms besides the type we humans are familiar with. There are species in which the fathers get pregnant (like seahorses). There are species where males will turn into females (or vice-versa) if it would help the species survive. There are lots of examples of parthenogensis (virgin birth). There are cases where a single individual (like a plant) will pollinate itself, but others where biology tries to prevent this, although the plant might be hermaphroditic. There are plants which have several different reproduction mechanisms; a piece of the root can produce a new individual, for example. Some organisms can engage in both sexual and asexual reproduction as well; earthworms, honeybees, and geckos can asexually reproduce. There are species with 3 or even more sexes (like the clam shrimp in the US, for example, which has 3 sexes, or possibly  the New Zealand lizard the tuatara, which appears to have 4 sexes. There are species where males just fertilize the eggs deposited by the female in some location (most fish). Bacteria and viruses reproduce in strange ways, by dividing, or by taking over the reproduction mechanism of some other organism. \n\nThe astounding variety of "sex" and/or reproduction just goes on and on and on. We are still learning about the amazing diversity of life on this planet. \n\nIf and when we ever discover life on other planets, you can be sure that they will have different ways to reproduce, that may or may not have anything to do with what we might recognize as sex, and probably using mechanisms we cannot even imagine.

Here's a few:\n\nMost roaches are female.\n\nThe females can clone themselves.\n\nFemales only need to have sex *once* - they store sperm for later use.  \n\nFemales can produce in excess of one million eggs over the course of their lifetime.\n\nRoaches are necrovores - they only eat things that are already dead.

Female anacondas do not devour the males!\n\n- Praying mantis\n- Many spiders\n- Ceratopogonid midges\n\nhttp://www.yesbutnobutyes.com/archives/ugly_animal_kingdom/index.html\n\n---------\nUpdate: An interesting article that discusses adaptive and nonadaptive hypotheses for sexual cannibalism in spiders.  The evidence suggests that, at least in spiders, there's a connection between foraging decisions and cannibalistic behaviour towards males. \nhttp://www.blackwell-synergy.com/links/doi/10.1046/j.1420-9101.2002.00363.x/full/\n(let me know if you cannot download the article)

You're wrong--There is homosexuality in the animal kingdom, and it's well documented.  The most famous same sex pair these days are the gay penguins in the Central Park Zoo.  Though they're just the most famous same-sex animal couple these days, it's not uncommon for most species.  Your assertion that there are "none" is simply without merit.

I think you mean hermaphrodite. That is an organism (even human, but rarely) that has both male and female sex organs.

Paella. No I think they eat sea anemones or other coelenterates and encorporate their nematocysts.

Of course all ‘higher’ animals enjoy having sex of course. Do you think they do it because they have rationalised that several months later the act will result in puppies?\n\n‘Lower’ animals like fish or invertebrates probably don’t enjoy it. It’s just a preprogrammed instinct and about as enjoyable as a washing machine going through a spin cycle.\n\n\nI have no idea where this myth that only dolphins and apes have sex for fun comes from. Quite clearly humans are the only species of mammal that has sex for any reason except for fun.\n\nWhile some humans will have sex for reproduction or out of obligation even if they don't or can't enjoy it no mammlas have that capability.

Sponges can multiply sexually or asexually.  Asexually a piece can bud off, float away, take root elsewhere, and begin to grow.  Sexually spermatozoa can swim through the water, find egg cells on another sponge, and fertilize the egg.  The result is a motile larva which can swim away and take root elsewhere, growing into a new sponge.

Courtship, mating and reproduction : Like all snakes and lizards, male sea snakes have two penises. They are called hemipenes, but each is an autonomous independently functioning penis and only one is used during mating. Mating takes place for long periods and sea snakes must surface for air during that time. The female controls breathing and as she swims to the surface the male is pulled along attached via the hemipenis. At the surface the male needs to gulp for air or he has to wait til the next time the female comes up the the surface to breathe. Males are unable to disengage until mating is finished. \n\nIn species where courtship has been studied, eg olive and turtlehead sea snakes, one or more males follow the female very closely and occasionally prod the head and neck of females. \n\nAll sea snakes except the latidcaudids give birth to live young after gestation periods that range from four to eleven months, depending on the species. Most species reproduce every year. The timing of the reproductive cycle varies enomously between species and also differs between geographical locations for the same species. \n\nYoung are born underwater and must be independent immediately to swim to the surface to breathe. There is no parental care. In some species look quite different to the adults eg juvenile olive sea snake are strongly banded while the adults are not.

Answer C; all the others have to do with sexual reproduction.

Nature tells us that homosexuality exists.  Are humans animals?  Are there homosexual humans?  Ergo...?\n\nThe fact that you have not quoted sources is of no consequence to me -- I am willing to take at face value that perhaps the cattle and lizards were setting domination patterns. I am curious as to how the motives of the lizards were determined to be "to humilate"?\n\nty kinney, of course, makes terrfic sense about the differences beetween humans and other animals and would worth be re-reading.  \n\nOf course, without any applicable citation, which would seem to be fairly easy to find, your insistence on the behavior of cattle weakens the argument, particularly when you assert such detail as "the male/male behavior documented never culminates it penetration! therefore it is not sexual in nature."  From your reaction to other posts, I assume you're after some sort of penetration?\n\nI must point out that an insistence on male/male penetration omits other non-dominance behaviors practiced by other animal species, such as courtship. \n\nTREE SWALLOWS:  Full cloacal contact has been observed by Wilson and Bull in  male Tree Swallows (Tachycineta bicolor), complete with  the “ticking” vocalizations which are apparently reserved for  heterosexual copulations in Tree Swallows.  They also note that dominance behaior among Tree Swallows is very different.\n\nLIZARD: A. carolinensis engage in both homosexual courtship and copulation -- with one male exhibiting the male behavior in courting being the mounter and the male exhibiting the female courtship behavior being mounted. Previous studies (Noble and Bradley in 1937) dismissed this as hierarchical behavior, but more recent observations (Cooper, 1977, and Sigmund, 1987) show a more thorough understanding of A. carolinensis society, including polygamy and consistent homosexual behavior in the absence of dominant males.\n\nBISON: Courtship, mounting, and full anal penetration between bulls is common among American bison. My Lakota brothers and sisters call them pte winkte —pte =bison and winkte is the word for two-spirit, their description of the transgendered  in their Nation.\n\nFEMALE CATTLE:  Mounting of female cattle in heat by other cows is common among domesticated cattle.  (Obviously, since no marital aids have been documented, no actual penetration occured.)  The same has not been observed among wild cattle in a study by Queensland College in Australia.  Although stress was cited by the observers, they also admitted the possibility of domestication as a factor -- so perhaps civilization figures into it.\n\nBONOBOS: Barbara Fruth and Gottfried Hohmann observed same-sex genital contacts in wild female bonobos.  They have already been mentioned here, I just thought I would give the citation, even though no penetration happened.\n\nZOO ANIMALS: The penguins, koalas, rabbits and others that have been documented as exhibiting homosexual behaviors have most often come from zoos or domesticated situations.  This does not necessarily indicate a corrupted or aberrant social system, but (Occam's Razor) they can be more easily observed.\n\nHYENAS: Actually, Ploss and Bartels have seen hyenas licking each other's genitals.  Hyenas are of particular interest in this discussion because, according the Bestiary of Barnabus, hyenas were believed to have predominantly homosexual sex, and were associated with homosexuals.  This view was strongly held in the time of Augustine, who was a zealot advocate of conversion.
