Rub-urinate
Self-anointing in animals, sometimes called anointing or anting, is a behaviour whereby a non-human animal smears odoriferous substances over themselves. These substances are often the secretions, parts, or entire bodies of other animals or plants. The animal may chew these substances and then spread the resulting saliva mixture over their body, or they may apply the source of the odour directly with an appendage, tool or by rubbing their body on the source. The functions of self-anointing differ between species, but it may act as self-medication, repel parasites, provide camouflage, aid in communication, or make the animal poisonous. Primates Several primate species self-anoint with various items such as millipedes, leaves and fruit. They sometimes drool while doing this. Both capuchin monkeys and squirrel monkeys perform urine washing, when they deposit a small quantity of urine onto the palm of a hand and then rub it on the sole of the opposite foot. It is thought to have m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hedgehog Self-anointing
A hedgehog is a spiny mammal of the subfamily Erinaceinae, in the eulipotyphlan family Erinaceidae. There are seventeen species of hedgehog in five genera found throughout parts of Europe, Asia, and Africa, and in New Zealand by introduction. There are no hedgehogs native to Australia and no living species native to the Americas. However, the extinct genus ''Amphechinus'' was once present in North America. Hedgehogs share distant ancestry with shrews (family Soricidae), with gymnures possibly being the intermediate link, and they have changed little over the last fifteen million years. Like many of the first mammals, they have adapted to a nocturnal way of life. Their spiny protection resembles that of porcupines, which are rodents, and echidnas, a type of monotreme. Etymology The name ''hedgehog'' came into use around the year 1450, derived from the Middle English ''heyghoge'', from ''heyg'', ''hegge'' ("hedge"), because it frequents hedgerows, and ''hoge'', ''hogge'' ("hog ...

Deer Penis
In traditional Chinese medicine, a deer penis (; Vietnamese: ''Lộc pín'') is said to have important therapeutic properties. Purported properties In Angang, Taiwan, women are reported to consume deer penis during pregnancy as it is said to have a fattening effect and to make the mother and child stronger. The Mayans were also known to extract the penis of the deer and roast it. Hippocrates recommended consuming deer penis to resolve sexual difficulties. During the 2008 Summer Olympics in China, the country banned deer penis wine, turtle blood and angelica root supplements from athletes' diets. This is because according to traditional Chinese medicine, deer penis, especially if ingested while soaked in alcohol (deer penis wine), is an effective remedy for athletic injuries. Chinese Olympic officials advised national athletes not to take the traditional remedy because it may contain the banned herb Ephedra. It joined steroids and various stimulants on the list of banned substan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
External Urethral Orifice (male)
The urinary meatus, (, ) also known as the external urethral orifice, is the opening of the urethra. It is the point where urine exits the urethra in both sexes and where semen exits the urethra in males. The meatus has varying degrees of sensitivity to touch. The meatus is located on the glans of the penis or in the vulval vestibule. In human males The male external urethral orifice is the external opening or urinary meatus, normally located at the tip of the glans penis, at its junction with the frenular delta. It presents as a vertical slit, possibly bounded on either side by two small labia-like projections, and continues longitudinally along the front aspect of the glans, which facilitates the flow of urine micturition. In some cases, the opening may be more rounded. This can occur naturally or may also occur as a side effect of excessive skin removal during circumcision. The meatus is a sensitive part of the male reproductive system. In human females The female external ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deer Urine
Urination, also known as micturition, is the release of urine from the urinary bladder through the urethra to the outside of the body. It is the urinary system's form of excretion. It is also known medically as micturition, voiding, uresis, or, rarely, emiction, and known colloquially by various names including peeing, weeing, and pissing. In healthy humans (and many other animals), the process of urination is under voluntary control. In infants, some elderly individuals, and those with neurological injury, urination may occur as a reflex. It is normal for adult humans to urinate up to seven times during the day. In some animals, in addition to expelling waste material, urination can mark territory or express submissiveness. Physiologically, urination involves coordination between the central, autonomic, and somatic nervous systems. Brain centres that regulate urination include the pontine micturition center, periaqueductal gray, and the cerebral cortex. In placental mamm ...

Rut (mammalian Reproduction)
The rut (from the Latin ''rugire'', meaning "to roar") is the mating season of certain mammals, which includes ruminants such as deer, sheep, camels, goats, pronghorns, bison, giraffes and antelopes, and extends to others such as skunks and elephants. The rut is characterized in males by an increase in testosterone, exaggerated sexual dimorphisms, increased aggression, and increased interest in females. The males of the species may mark themselves with mud, undergo physiological changes or perform characteristic displays in order to make themselves more visually appealing to the females. Males also use olfaction to entice females to mate using secretions from glands and self-anointing in animals, soaking in their own urine. During the rut (known as the ''rutting period'' and in domestic sheep management as ''Glossary of sheep husbandry, tupping''), males often rub their antlers or horn (anatomy), horns on trees or shrubs, fight with each other, Wallowing in animals, wallow in mud o ...

Erection
An erection (clinically: penile erection or penile tumescence) is a physiological phenomenon in which the penis becomes firm, engorged, and enlarged. Penile erection is the result of a complex interaction of psychological, neural, vascular, and endocrine factors, and is often associated with sexual arousal or sexual attraction, although erections can also be spontaneous. The shape, angle, and direction of an erection varies considerably between humans. Physiologically, an erection is required for a male to effect vaginal penetration or sexual intercourse and is triggered by the parasympathetic division of the autonomic nervous system, causing the levels of nitric oxide (a vasodilator) to rise in the trabecular arteries and smooth muscle of the penis. The arteries dilate causing the corpora cavernosa of the penis (and to a lesser extent the corpus spongiosum) to fill with blood; simultaneously the ischiocavernosus and bulbospongiosus muscles compress the veins of the ...

Sambar Deer
The sambar (''Rusa unicolor'') is a large deer native to the Indian subcontinent and Southeast Asia that is listed as a vulnerable species on the IUCN Red List since 2008. Populations have declined substantially due to severe hunting, local insurgency, and industrial exploitation of habitat. The name "sambar" is also sometimes used to refer to the Philippine deer called the "Philippine sambar", and the Javan rusa called the "Sunda sambar". Description The appearance and the size of the sambar vary widely across its range, which has led to considerable taxonomic confusion in the past; over 40 different scientific synonyms have been used for the species. In general, they attain a height of at the shoulder and may weigh as much as , though more typically .Burnie D and Wilson DE (Eds.), ''Animal: The Definitive Visual Guide to the World's Wildlife''.

Chital
The chital or cheetal (''Axis axis''; ), also known as the spotted deer, chital deer, and axis deer, is a deer species native to the Indian subcontinent. It was first described and given a binomial name by German naturalist Johann Christian Polycarp Erxleben in 1777. A moderate-sized deer, male chital reach and females at the shoulder. While males weigh , females weigh around . It is sexually dimorphic; males are larger than females, and antlers are present only on males. The upper parts are golden to rufous, completely covered in white spots. The abdomen, rump, throat, insides of legs, ears, and tail are all white. The antlers, three-pronged, are nearly long. Etymology The vernacular name "chital" (pronounced ) comes from ''cītal'' ( hi, चीतल), derived from the Sanskrit word ' (चित्रल), meaning "variegated" or "spotted". The name of the cheetah has a similar origin. Variations of "chital" include "cheetal" and "cheetul". Other common names for the chita ...

Rump (animal)
The rump or croup, in the external morphology of an animal, is the portion of the posterior dorsum – that is, posterior to the loins and anterior to the tail. Anatomically, the rump corresponds to the sacrum. The tailhead or dock is the beginning of the tail, where the tail joins the rump. It is known also as the base or root of the tail, and corresponds to the human sacrococcygeal symphysis. In some mammals the tail may be said to consist of the tailbone (meaning the bony column, muscles, and skin) and the skirt (meaning the long hairs growing from the tailbone). In birds, similarly, the tail consists of tailbone and tailfan (tail fan). Some animals are subjected to docking, the amputation of the tailbone at or near the dock. These include dogs, cats, sheep, pigs, and horses. Humans have a remnant tail, the coccyx, and the human equivalent of docking is coccygectomy. Usage Usage varies from animal to animal. Birds and cattle are said to have a rump and tailhead ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mating
In biology, mating is the pairing of either opposite-sex or hermaphroditic organisms for the purposes of sexual reproduction. ''Fertilization'' is the fusion of two gametes. ''Copulation'' is the union of the sex organs of two sexually reproducing animals for insemination and subsequent internal fertilization. Mating may also lead to external fertilization, as seen in amphibians, fishes and plants. For most species, mating is between two individuals of opposite sexes. However, for some hermaphroditic species, copulation is not required because the parent organism is capable of self-fertilization (autogamy); for example, banana slugs. The term ''mating'' is also applied to related processes in bacteria, archaea and viruses. Mating in these cases involves the pairing of individuals, accompanied by the pairing of their homologous chromosomes and then exchange of genomic information leading to formation of recombinant progeny (see mating systems).

Nile Lechwe
The Nile lechwe or Mrs Gray's lechwe (''Kobus megaceros'') is an endangered species of antelope found in swamps and grasslands in Sudan and Ethiopia. Description Males are an average of long and tall at the shoulders, and weigh between , while females are an average of long, tall at the shoulders, and weigh . Nile lechwes live an average of 10 to 11.5 years, and most uncommonly 19 years. Their coats are shaggy with the hair on the cheeks particularly long in both sexes, and males may have even longer hair on their necks. Nile lechwe exhibit extreme sexual dimorphism. Females are golden-brown with white underbellies and no horns. Juveniles also have a golden-brown coat, but the color changes to dark brown in young males when they reach two to three years of age. Adult males are blackish-brown to russet with white 'hoods' over their shoulders and small white patches over their eyes. The horns of the adult males are long, strongly ridged at their bases and are curved at the t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
