Polyandry also occurs in some primates such as marmosets, mammal groups, the marsupial genus' Antechinus and bandicoots, around 1% of all bird species, such as jacanas and dunnocks, insects such as honeybees, and fish such as pipefish.
Polyandry. The mating of one female with more than one male while each male mates with only one female is known as polyandry (literally, "many males"). It is a rare mating system, occurring in less than one percent of all bird species, and is found mostly in shorebirds.
In the animal kingdom, when it comes to mating, promiscuity is the rule rather than the exception. About 90 percent of mammals have multiple mates, and cheating on social mates is observed in almost all species. In fact, only 3 to 10 percent of mammals are even socially monogamous.

…a phenomenon referred to as polyandry, examples of which include spotted sandpipers (Actitis macularia), phalaropes (Phalaropus), jacanas (tropical species in the family Jacanidae), and a few human societies such as those once found in the Ladakh region of the Tibetan plateau.

Although polygamy also involves mating with multiple partners, it often refers to cases in which individuals form relatively stable associations with two or more mates. Most such species exhibit polygyny, in which males have multiple partners.
If a human were indeed inclined and able to impregnate a monkey, post-zygotic mechanisms might result in a miscarriage or sterile offspring. The further apart two animals are in genetic terms, the less likely they are to produce viable offspring.
1. Brown antechinus. For two weeks every mating season, a male will mate as much as physically possible, sometimes having sex for up to 14 hours at a time, flitting from one female to the next. And all that testosterone revs up his stress hormone production into overdrive, crashing his immune system.
Most of you already know that seahorses are unconventional in the sense that the male of the pair carries the babies to term. A fact that is so rare they may very well be the only animal species on earth to do so. But some species of seahorse are also monogamous and choose to stick with a single mate for life.
Polyandry very rare because it involves sex role reversal, where females invest less in offspring while males invest more. Pipefishes, a relative of seahorses, exhibit polyandry where females compete for access to males.
First, females compete for access to the highest quality males and once mated, those males are no longer available. In that case, females can breed with an available male and engage in extra-pair copulations with their preferred male (Møller, 1992).
Animals that have been claimed to be subject to superfetation include rodents (mice and rats), rabbits, horses, sheep, marsupials (kangaroos and sugar gliders), felines, and primates (humans).
Animals don't have beliefs or taboos that stop them from breeding with close relatives, and there are many examples of littermates or closely related dogs or cats who have bred together. Sometimes there's no obvious problems and other times there are serious genetic anomalies.
Gynandromorphs (“gyne” from Greek meaning female, “andro” for male, and “morph” meaning variety) are individual animals that have both genetically male and female tissues and often have observable male and female characteristics.
Many species of fish, like the kobudai, are known as “sequential hermaphrodites”: they can switch sex permanently at a specific point in their lives. The majority of “sequential hermaphrodites” are known as “protogynous” (Greek for “female first”): they switch from female to male.
A hermaphrodite is an organism that has both male and female reproductive organs and can perform both the male and female parts of reproduction. In some hermaphrodites, the animal starts out as one sex and switches to the other sex later in its life.
Bonobos are highly promiscuous, engaging in sexual interactions more frequently than any other primate, and in just about every combination from heterosexual to homosexual unions.
The female red-sided garter snake, a species native to Manitoba, Canada, has no shortage of potential lovers. According to Christopher Friesen at the University of Wollongong in Australia, anywhere from 10 to 30 attentive males may pursue her at once, literally enveloping her with their love.
A large-scale study found that human copulation lasts five minutes on average, although it may rarely last as long as 45 minutes.
The phenomenon of spawning without male contribution—known as parthenogenesis—is common in invertebrates, such as ants. Scientists have also observed it in vertebrates before, including fish, lizards, birds, and snakes, but it's rare and only seen when animals are captive or when no males are present.
While they don't derive pleasure from sexual activities, dogs are driven by their instincts to procreate. Ensuring your dog is comfortable during and after mating is critical, as the process can be physically stressful for her.
Whether or not dogs are more attracted to one gender can't be objectively answered because all dogs and people are different. But, dogs generally tend to be more attracted to a specific set of behaviors that are exhibited mostly by adult women. It's not that dogs are exclusively attracted to female adults.
In addition to standard penetrative encounters, they frequently engage in manual genital massage and oral sex. These positionally creative apes are also the only animal (other than us) to practice tongue-on-tongue kissing or face-to-face penetrative sex.
Unlike many other animals, dolphins do not mate purely for procreation. Rather, these highly social and intelligent animals have sex for pleasure as well. Further, this means they can have sex throughout the year, rather than being limited to a mating season.
