Non-reproductive Sexual Behaviour In Animals
Animal non-reproductive sexual behavior encompasses sexual activities that animals participate in which do not lead to the reproduction of the species. Although procreation continues to be the primary explanation for sexual behavior in animals, recent observations on animal behavior have given alternative reasons for the engagement in sexual activities by animals. Animals have been observed to engage in sex for social interaction, bonding, exchange for significant materials, affection, mentorship pairings, sexual enjoyment, or as demonstration of social rank. Observed non-procreative sexual activities include non- copulatory mounting (without insertion, or by a female, or by a younger male who does not yet produce semen), oral sex, genital stimulation, anal stimulation, interspecies mating, same-sex sexual interaction, and acts of affection, although it is doubted that they have done this since the beginning of their existence. There have also been observations of sex with cub p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Animal Sexual Behaviour
Animal sexual behaviour takes many different forms, including within the same species. Common mating or Reproduction, reproductively motivated systems include Monogamous pairing in animals, monogamy, Polygyny in animals, polygyny, Polyandry in nature, polyandry, Animal sexual behaviour#Polygamy, polygamy and Promiscuity#Other animals, promiscuity. Other sexual behaviour may be reproductively motivated (e.g. Sexual coercion among animals, sex apparently due to duress or coercion and situational sexual behaviour) or Non-reproductive sexual behavior in animals, non-reproductively motivated (e.g. Homosexual behavior in animals, homosexual sexual behaviour, bisexuality, bisexual sexual behaviour, cross-species sex, Paraphilia, sexual arousal from objects or places, Necrophilia in animals, sex with dead animals, etc.). When animal sexual behaviour is reproductively motivated, it is often termed ''mating'' or ''Copulation (zoology), copulation''; for most non-human mammals, mating and ...

Felidae
Felidae ( ) is the Family (biology), family of mammals in the Order (biology), order Carnivora colloquially referred to as cats. A member of this family is also called a felid ( ). The 41 extant taxon, extant Felidae species exhibit the greatest diversity in fur patterns of all terrestrial carnivores. Cats have retractile claws, slender muscular bodies and strong flexible forelimbs. Their teeth and facial muscles allow for a powerful bite. They are all obligate carnivores, and most are solitary predators ambushing or stalking their prey. Wild cats occur in Africa, Europe, Asia and the Americas. Some wild cat species are adapted to forest and savanna habitats, some to arid environments, and a few also to wetlands and mountainous terrain. Their activity patterns range from nocturnal and crepuscular to Diurnality, diurnal, depending on their preferred prey species. Reginald Innes Pocock divided the extant Felidae into three subfamilies: the Pantherinae, the Felinae and the Acin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Japanese Macaques
The Japanese macaque (''Macaca fuscata''), also known as the snow monkey, is a terrestrial Old World monkey species that is native to Japan. Colloquially, they are referred to as "snow monkeys" because some live in areas where snow covers the ground for months each year – no other non-human primate lives farther north, nor in a colder climate. Individuals have brownish grey fur, pinkish-red faces, and short tails. Two subspecies are known. In Japan, the species is known as ''Nihonzaru'' (ニホンザル, a combination of ''Nihon'' 日本 "Japan" + ''saru'' 猿 "monkey") to distinguish it from other primates, but the Japanese macaque is very familiar in Japan—as it is the only species of monkey in Japan—so when Japanese people simply say ''saru'', they usually have the Japanese macaque in mind. Physical characteristics The Japanese macaque is sexually dimorphic. Males weigh on average , while females average .Fooden J, Aimi M. (2005) "Systematic review of Japanese macaq ...

Rhesus Macaque
The rhesus macaque (''Macaca mulatta''), colloquially rhesus monkey, is a species of Old World monkey. There are between six and nine recognised subspecies split between two groups, the Chinese-derived and the Indian-derived. Generally brown or grey in colour, it is in length with a tail and weighs . It is native to South Asia, South, Central Asia, Central, and Southeast Asia and has the widest geographic range of all non-human primates, occupying a great diversity of altitudes and habitats. The rhesus macaque is diurnality, diurnal, arboreal, and terrestrial. It is mostly herbivorous, feeding mainly on fruit, but also eating seeds, roots, buds, Bark (botany), bark, and cereals. Rhesus macaques living in cities also eat human food and trash. They are gregarious, with troops comprising 20–200 individuals. The social groups are matrilineal. Individuals communicate with a variety of facial expressions, vocalisations, body postures, and gestures. As a result of the rhesus macaq ...

Stump-tailed Macaque
The stump-tailed macaque (''Macaca arctoides''), also called the bear macaque, is a species of macaque native to South Asia and Southeast Asia. In India, it occurs south of the Brahmaputra River, in the northeastern part of the country. Its range in India extends from Assam and Meghalaya to eastern Arunachal Pradesh, Nagaland, Manipur, Mizoram and Tripura. It is primarily frugivorous but eats many types of vegetation, such as seeds, leaves and roots. It also hunts freshwater crabs, frogs, bird eggs and insects. Characteristics The stump-tailed macaque has long, thick, dark brown fur covering its body, but its face and its short tail, which measures between , are hairless. Infants are born white and darken as they mature. As they age, their bright pink or red faces darken to brown or nearly black and lose most of their hair. Males are larger than females, measuring long and weighing , while females measure and weigh . Males' canine teeth, which are important for establishing dom ...

Macaca (genus)
The macaques () constitute a genus (''Macaca'') of gregarious Old World monkeys of the subfamily Cercopithecinae. The 23 species of macaques inhabit ranges throughout Asia, North Africa, and Europe (in Gibraltar). Macaques are principally frugivorous (preferring fruit), although their diet also includes seeds, leaves, flowers, and tree bark. Some species such as the long-tailed macaque (''M. fascicularis''; also called the crab-eating macaque) will supplement their diets with small amounts of meat from shellfish, insects, and small mammals. On average, a southern pig-tailed macaque (''M. nemestrina'') in Malaysia eats about 70 large rats each year. All macaque social groups are arranged around dominant matriarchs. Macaques are found in a variety of habitats throughout the Asian continent and are highly adaptable. Certain species are synanthropic, having learned to live alongside humans, but they have become problematic in urban areas in Southeast Asia and are not suitable to ...

Orangutan
Orangutans are great apes native to the rainforests of Indonesia and Malaysia. They are now found only in parts of Borneo and Sumatra, but during the Pleistocene they ranged throughout Southeast Asia and South China. Classified in the genus ''Pongo'', orangutans were originally considered to be one species. In 1996, they were divided into two species: the Bornean orangutan (''P. pygmaeus'', with three subspecies) and the Sumatran orangutan (''P. abelii''); a third species, the Tapanuli orangutan (''P. tapanuliensis''), was identified definitively in 2017. The orangutans are the only surviving members of the subfamily Ponginae, which diverged genetically from the other hominids (gorillas, chimpanzees, and humans) between 19.3 and 15.7 million years ago. The most arboreal of the great apes, orangutans spend most of their time in trees. They have proportionally long arms and short legs, and have reddish-brown hair covering their bodies. Adult males weigh about , while female ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gorilla
Gorillas are primarily herbivorous, terrestrial great apes that inhabit the tropical forests of equatorial Africa. The genus ''Gorilla'' is divided into two species: the eastern gorilla and the western gorilla, and either four or five subspecies. The DNA of gorillas is highly similar to that of humans, from 96 to 99% depending on what is included, and they are the next closest living relatives to humans after the chimpanzees. Gorillas are the largest living primates, reaching heights between , weights between , and arm spans up to , depending on species and sex. They tend to live in troops, with the leader being called a silverback. The eastern gorilla is distinguished from the western by darker fur colour and some other minor morphological differences. Gorillas tend to live 35–40 years in the wild. Gorillas' natural habitats cover tropical or subtropical forest in Sub-Saharan Africa. Although their range covers a small percentage of Sub-Saharan Africa, gorillas c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anal Sex
Anal sex or anal intercourse principally means the insertion and pelvic thrusting, thrusting of the Erection, erect human penis, penis into a person's Human anus, anus, or anus and rectum, for sexual pleasure.Sepages 270–271for anal sex information, anpage 118for information about the clitoris. Other forms of anal sex include Fingering (sexual act)#Anus, anal fingering, the use of sex toys, anilingus, and Pegging (sexual practice), pegging. Although ''anal sex'' most commonly means penileanal penetration, sources sometimes use ''anal intercourse'' to exclusively denote penileanal penetration, and ''anal sex'' to denote any form of anal Human sexual activity, sexual activity, especially between pairings as opposed to anal masturbation. While anal sex is commonly associated with Gay men, male homosexuality, research shows that not all homosexual men engage in anal sex and that it is not uncommon in Heterosexuality, heterosexual relationships.

Testes
A testicle or testis ( testes) is the gonad in all male bilaterians, including humans, and is homologous to the ovary in females. Its primary functions are the production of sperm and the secretion of androgens, primarily testosterone. The release of testosterone is regulated by luteinizing hormone (LH) from the anterior pituitary gland. Sperm production is controlled by follicle-stimulating hormone (FSH) from the anterior pituitary gland and by testosterone produced within the gonads. Structure Appearance Males have two testicles of similar size contained within the scrotum, which is an extension of the abdominal wall. Scrotal asymmetry, in which one testicle extends farther down into the scrotum than the other, is common. This is because of the differences in the vasculature's anatomy. For 85% of men, the right testis hangs lower than the left one. Measurement and volume The volume of the testicle can be estimated by palpating it and comparing it to ellipsoids (an ...

Autoeroticism Or Masturbation
Autoeroticism (also known as autoerotism or self-gratification) is sexual activity involving only one participant. It is the use of one's own body and mind to stimulate oneself sexually. As an extension of masturbation, it usually means one of several activities done by oneself to fulfill their own sexual desire. Masturbation has a similar meaning, but is not synonymous; masturbation is only ''physical'' stimulation of the genitals by oneself while autoeroticism encompasses all stimulation by oneself (masturbation or sexual thoughts), as well as involuntary experiences (wet dreams or spontaneous sexual arousal). The term was popularized toward the end of the 19th century by British sexologist Havelock Ellis, who defined autoeroticism as "the phenomenon of spontaneous sexual emotion generated in the absence of an external stimulus proceeding, directly or indirectly, from another person". Autosexuality is a similar term, which is a sexuality for oneself, and is usually accompa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
