how long is a giraffes neck

These vertebrae are extremely long and are separated by very flexible joints. [63] When swimming, the thorax would be weighed down by the front legs, making it difficult for the animal to move its neck and legs in harmony[62][63] or keep its head above the surface. Comparisons between giraffes and their ancient relatives suggest that vertebrae close to the skull lengthened earlier, followed by lengthening of vertebrae further down. The giraffe has a special adaptation in its neck to regulate pressure, which prevents excessive blood flow to its brain when it lowers its head. The giraffe has a special adaptation in its neck to regulate pressure, which prevents excessive blood flow to its brain when it lowers its head. Mothers in such a group may sometimes leave their calves with one female while they forage and drink elsewhere. Although the neck of a giraffe is about five feet long in the case of female giraffes and seven feet in the case of males, giraffes also have towering legs, which can reach nine feet in length (for females) and 11 feet (in males). Thus, these nerve cells have a length of nearly 5 m (16 ft) in the largest giraffes. These nerves are longer in the giraffe than in any other living animal;[75] the left nerve is over 2 m (6 ft 7 in) long. 1988. The length of the Giraffe neck gives the illusion of a complex anatomical structure underneath. The name "giraffe" has its earliest known origins in the Arabic word zarāfah (زرافة),[2] perhaps borrowed from the animal's Somali name geri. Animation describing how and why giraffes have developed such long necks. [10] Each individual giraffe has a unique coat pattern. Giraffe Factoid of the Day: Though known for their long necks, giraffes actually have the same number of neck vertebrae as humans—which is seven total. [7] Males develop calcium deposits that form bumps on their skulls as they age. [136], Giraffes were probably common targets for hunters throughout Africa. This advantage is real, as giraffes can and do feed up to 4.5 m (15 ft) high, while even quite large competitors, such as kudu, can feed up to only about 2 m (6 ft 7 in) high. [70] As a ruminant, the giraffe first chews its food, then swallows it for processing and then visibly passes the half-digested cud up the neck and back into the mouth to chew again. camelopardalis", 10.2305/IUCN.UK.2018-2.RLTS.T88420707A88420710.en, "Evaluating conservation effectiveness in a Tanzanian community wildlife management area", "Quantifying the ecological success of a community-based wildlife conservation area in Tanzania", "Chimpanzees among 33 breeds selected for special protection", "Good News for Giraffes at CITES CoP18 > Newsroom", "Giraffe translocations: A review and discussion of considerations", "Giraffe translocation population viability analysis", "Surge in wildlife killings is wiping out giraffes", https://en.wikipedia.org/w/index.php?title=Giraffe&oldid=993522285, CS1 maint: DOI inactive as of October 2020, Wikipedia indefinitely semi-protected pages, Short description is different from Wikidata, Articles containing Middle English (1100-1500)-language text, Articles containing Italian-language text, Articles containing potentially dated statements from 2010, All articles containing potentially dated statements, Creative Commons Attribution-ShareAlike License, This page was last edited on 11 December 2020, at 01:47. Giraffes live in herds of related females and their offspring, or bachelor herds of unrelated adult males, but are gregarious and may gather in large aggregations. Spermatogenesis in male giraffes begins at three to four years of age. (680 kg), while males grow up to 18 feet (5.5 m) tall and weigh up to 3,000 lbs. In a study that shows just how cool giraffes can get, researchers have tested a hypothesis that the giraffe's long neck actually helps regulate their body temperature. [43] The giraffe is a protected species in most of its range. As such, the wall of the heart can be as thick as 7.5 cm (3.0 in). During courtship, males emit loud coughs. Help save giraffe. [134][135] Aerial survey is the most common method of monitoring giraffe population trends in the vast roadless tracts of African landscapes, but aerial methods are known to undercount giraffes. The neck has several important roles and specific functions: Feeding. Male giraffes can be 18 feet tall at the top of the horns; Giraffes have 2 to 5 horns called "occicones" The giraffes neck is 6 to 8 feet long and can weigh over 600 pounds; Giraffes "chew their cud" just like cows; Giraffes defend themselves by kicking; A giraffes kick can kill a lion! [86] Calves are at risk of predation, and a mother giraffe will stand over her calf and kick at an approaching predator. Males can be up to 18ft (5.5m tall), females a little less. [56] The "competing browsers hypothesis" was originally suggested by Charles Darwin and challenged only recently. [132] In 2019, giraffes were listed under Appendix 2 of the Conference of the Parties to the UN Convention on International Trade in Endangered Species (CITES), which will now document international trade in giraffe parts, such as hides, bones and meat. Tanzania. [4] The animal's faeces come in the form of small pellets. [56] Appearance is a reliable guide to the sex or age of a giraffe: the ossicones of females and young are thin and display tufts of hair on top, whereas those of adult males end in knobs and tend to be bald on top. [96] Males must wait until they are at least seven years old to gain the opportunity to mate. They are the all-seeing mammal who pokes above the treetops. At up to 5.8 metres tall (19 feet), giraffes are the tallest animal on land, thanks to their unusually long necks. [53], The skin of a giraffe is mostly gray,[48] or tan. [109][110][111], Humans have interacted with giraffes for millennia. [50]:56 The Medici giraffe was a giraffe presented to Lorenzo de' Medici in 1486. It could now see and hear all but it could not speak as "silence is wisdom". [67] There is also research suggesting that browsing competition is intense at lower levels, and giraffes feed more efficiently (gaining more leaf biomass with each mouthful) high in the canopy. [76] Each nerve cell in this path begins in the brainstem and passes down the neck along the vagus nerve, then branches off into the recurrent laryngeal nerve which passes back up the neck to the larynx. [50]:26 The giraffe's molars have a rough surface. Each vertebra is rather large, measuring up to ten inches long. Although the neck of a giraffe is about five feet long in the case of female giraffes and seven feet in the case of males, giraffes also have towering legs, which can reach nine feet in length (for females) and 11 feet (in males). [49]:76 A gallbladder is generally present during fetal life, but it may disappear before birth. [21] Community-based conservation efforts outside national parks are also effective at protecting giraffes and their habitats. The giraffe is the tallest land mammal alive, its long legs and neck contributing to its impressive stature. He was right. [127][128] Private game reserves have contributed to the preservation of giraffe populations in southern Africa. [91] A courting male may lick a female's tail, rest his head and neck on her body or nudge her with his horns. Bohlinia closely resembled modern giraffes, having a long neck and legs and similar ossicones and dentition. [10] Some biologists suggest the modern giraffes descended from G. jumae;[14] others find G. gracilis a more likely candidate. Foster (1976/1982): The Giraffe. [49]:66 Located at both sides of the head, the giraffe's large, bulging eyes give it good all-round vision from its great height. With each step, the animal swings its head. Computer scientists have modeled the coat patterns of several subspecies using reaction–diffusion mechanisms. [42] Giraffes would probably not be competent swimmers as their long legs would be highly cumbersome in the water,[62] although they could possibly float. Calves will emit snorts, bleats, mooing and mewing sounds. [85] For research purposes, a "group" has been defined as "a collection of individuals that are less than a kilometre apart and moving in the same general direction. [50]:29 The point of articulation between the cervical and thoracic vertebrae of giraffes is shifted to lie between the first and second thoracic vertebrae (T1 and T2), unlike most other ruminants where the articulation is between the seventh cervical vertebra (C7) and T1. The giraffes tongue is about 18 inches long As the world’s tallest animal, giraffes can grow as high as 19 feet and weigh up to 2,800 lbs. The reason for the giraffe’s . [50]:36 The rear of each hoof is low and the fetlock is close to the ground, allowing the foot to provide additional support to the animal's weight. At up to 5.8 metres tall (19 feet), giraffes are the tallest animal on land, thanks to their unusually long necks. [7] Giraffes can also suffer from a skin disorder, which comes in the form of wrinkles, lesions or raw fissures. [50]:25 Giraffes see in colour[50]:26 and their senses of hearing and smell are also sharp. [42][50]:40, Male giraffes use their necks as weapons in combat, a behaviour known as "necking". [7] Their meat was used for food. The giraffe is the tallest living mammal on the planet and its famous long neck is not the only body part which accounts for this record. Asian giraffes are hypothesised to have had more okapi-like colourations. [7], A giraffe has only two gaits: walking and galloping. [49]:78 They have four chambered stomachs, as in all ruminants, and the first chamber has adapted to their specialized diet. [61] If the giraffe wants to bend down to drink, it either spreads its front legs or bends its knees. It caused a great stir on its arrival in Florence. This animal was medium-sized, slender and antelope-like. The long and powerful neck of giraffes is their most characteristic feature, measuring up to 6.5 feet in length and formed by seven cervical vertebrae as in other mammals, including the human being, but with the difference that each of vertebrae has a large size reaching up to 11 inches. [37]:327–29 The giraffe can reach a sprint speed of up to 60 km/h (37 mph),[59] and can sustain 50 km/h (31 mph) for several kilometres. [2] "Camelopard" is an archaic English name for the giraffe deriving from the Ancient Greek for camel and leopard, referring to its camel-like shape and its leopard-like colouring. [68][69] However, scientists disagree about just how much time giraffes spend feeding at levels beyond the reach of other browsers,[14][56][67][70] Its heart, which can weigh more than 11 kg (25 lb) and measures about 60 cm (2 ft) long, must generate approximately double the blood pressure required for a human to maintain blood flow to the brain.

Their food source is leaves, fruits and flowers of woody plants, primarily acacia species, which they browse at heights most other herbivores cannot reach. Lake Eyasi, NW [14] However, one objection is that it fails to explain why female giraffes also have long necks. [37]:324 A giraffe eats around 34 kg (75 lb) of foliage daily. [42] Females watching calving pools will only alert their own young if they detect a disturbance, although the others will take notice and follow. : 66 Located at both … More Giraffe Facts. The proportion of same-sex activities varied from 30 to 75 percent. [42] Also, a median lump, which is more prominent in males, emerges at the front of the skull. In low intensity necking, the combatants rub and lean against each other. Then the factor of natural selection came into light. [50] Habitat destruction has hurt the giraffe. Surprisingly, even with its long neck, the giraffe has the same number of vertebrae in its neck as humans do. In 1414, a giraffe was shipped from Malindi to Bengal. [113] How the giraffe got its height has been the subject of various African folktales,[14] including one from eastern Africa which explains that the giraffe grew tall from eating too many magic herbs. [50]:48–49 The giraffe was also known to the Greeks and Romans, who believed that it was an unnatural hybrid of a camel and a leopard or a panther and called it camelopardalis. The giraffe's chief distinguishing characteristics are its extremely long neck and legs, its horn-like ossicones, and its distinctive coat patterns. [106], The local, seasonal presence of large herds of migratory wildebeests and zebras reduces predation pressure on giraffe calves and increases their survival probability. It’s like a majestic long-necked horse that just wants to munch on some leaves in the canopies of trees. The giraffe is the tallest living mammal on the planet and its famous long neck is not the only body part which accounts for this record. [8], The giraffe is one of only two living genera of the family Giraffidae in the order Artiodactyla, the other being the okapi. Necking is used to establish dominance and males that win necking bouts have greater reproductive success. Surprisingly, even with its long neck, the giraffe has the same number of vertebrae in its neck as humans do. [102] Giraffes are the most common food source for the big cats in Kruger National Park, comprising nearly a third of the meat consumed, although only a small portion of the giraffes were probably killed by predators, as a majority of the consumed giraffes appeared to be scavenged. Giraffes live in grasslands and open woodlands in small herds. To get back up, it first gets on its knees and spreads its hind legs to raise its hindquarters. As much as 79% of giraffes show signs of the disease in Ruaha National Park, but it did not cause mortality in Tarangire and is less prevalent in areas with fertile soils. When courting, dominant males will keep subordinate ones at bay. [15][16] Some researchers have hypothesised that this new habitat coupled with a different diet, including acacia species, may have exposed giraffe ancestors to toxins that caused higher mutation rates and a higher rate of evolution. [66] However, this proposition is not generally accepted, as T1 has other morphological features, such as an articulating rib, deemed diagnostic of thoracic vertebrae, and because exceptions to the mammalian limit of seven cervical vertebrae are generally characterised by increased neurological anomalies and maladies. [13] Further climate changes caused the extinction of the Asian giraffes, while the African giraffes survived and radiated into several new species. Males can be up to 18ft (5.5m tall), females a little less. Intermittent short "deep sleep" phases while lying are characterised by the giraffe bending its neck backwards and resting its head on the hip or thigh, a position believed to indicate paradoxical sleep. Its Biology, Behavior, and Ecology. [50]:81, Giraffes continue to have a presence in modern culture. Giraffes have seven neck bones, the same number as other mammals, and the length of the neck is the result of a disproportionate lengthening of the cervical vertebrae, not from the addition of more vertebrae. "[86] More recent studies have found that giraffes have long-term social associations and may form groups or pairs based on kinship, sex or other factors, and these groups regularly associate with one another in larger communities or sub-communities within a fission–fusion society. The tail hairs served as flyswatters, bracelets, necklaces, and thread. In Tanzania, it appears to be caused by a nematode, and may be further affected by secondary infections. [49]:71 They comprise 52–54 per cent of the length of the giraffe's vertebral column, compared with the 27–33 percent typical of similar large ungulates, including the giraffe's closest living relative, the okapi. [117], The Egyptians gave the giraffe its own hieroglyph, named 'sr' in Old Egyptian and 'mmy' in later periods. [37] Different parts of their bodies were used for different purposes. [52] The skin underneath the blotches may serve as windows for thermoregulation, being sites for complex blood vessel systems and large sweat glands. [50]:49 They also kept giraffes as pets and shipped them around the Mediterranean. As you can guess, that doesn't exactly make for a light load to tote. [4] Mothers tend to feed in open areas, presumably to make it easier to detect predators, although this may reduce their feeding efficiency. Spotting does not often reach below the hocks and almost never to the hooves. [22] A 2007 study on the genetics of giraffes, suggested six species. The back legs look shorter than the front legs, but they are about the same length. [11] Samotherium was a particularly important transitional fossil in the giraffe lineage as its cervical vertebrae was intermediate in length and structure between a modern giraffe and an okapi, and was more vertical than the okapi's. Surprisingly, even with its long neck, the giraffe has the same number of vertebrae in its neck as humans and other mammals. These animals may have evolved from the extinct family Palaeomerycidae which might also have been the ancestor of deer. The contestants will try to dodge each other's blows and then get ready to counter. [43] In 2017, severe droughts in northern Kenya have led to increased tensions over land and the killing of wildlife by herders, with giraffe populations being particularly hit. It has been hypothesized that giraffes with longer necks were selected for over time because they could reach food higher up in the trees, so didn’t have to compete with other browsers … [50]:54 During the Middle Ages, giraffes were known to Europeans through contact with the Arabs, who revered the giraffe for its peculiar appearance. [17] The coat patterns of modern giraffes may also have coincided with these habitat changes. [49]:78–79 It is common for a giraffe to salivate while feeding. [37] The Humr people of Kordofan consume the drink Umm Nyolokh, which is prepared from the liver and bone marrow of giraffes. The calf is about 6 feet tall at birth. Dominant males gain mating access to females, which bear the sole responsibility for raising the young. [83] Giraffes browse on the twigs of trees, preferring trees of the subfamily Acacieae and the genera Commiphora and Terminalia,[4] which are important sources of calcium and protein to sustain the giraffe's growth rate. Make a donation to support our work in Africa. Normally, giraffes can coexist with livestock, since they do not directly compete with them. [57] It appears that a suspensory ligament allows the lanky legs to support the animal's great weight. [86] Once an oestrous female is detected, the male will attempt to court her. At least 11 main aromatic chemicals are in the fur, although indole and 3-methylindole are responsible for most of the smell. But for most mammals, it’s 7. Kordofan, about 10° N, 28° E (as fixed by Harper, 1940). and J. This is known as a "calving pool". [89] Particularly stable giraffe groups are those made of mothers and their young,[86] which can last weeks or months. [19] A 2011 study using detailed analyses of the morphology of giraffes, and application of the phylogenetic species concept, described eight species of living giraffes. They may also have disappeared from Angola, Mali, and Nigeria, but have been introduced to Rwanda and Swaziland. [20][21] In 2001, a two-species taxonomy was proposed. Male giraffes can be 18 feet tall at the top of the horns; Giraffes have 2 to 5 horns called "occicones" The giraffes neck is 6 to 8 feet long and can weigh over 600 pounds; Giraffes "chew their cud" just like cows; Giraffes defend themselves by kicking; A giraffes kick can kill a lion! He gave it the binomial name Cervus camelopardalis. They prefer Acacieae, Commiphora, Combretum and open Terminalia woodlands over denser environments like Brachystegia woodlands. Despite its long neck and legs, the giraffe's body is relatively short. The divergence of giraffe and okapi lineages dates to around 11.5 mya. One, proposed by Darwin and called the competing browser hypothesis, posits that giraffes evolved long necks to reach food inaccessible to other animals. [138] In the 19th century, European explorers began to hunt them for sport. [126] The primary causes for giraffe population declines are habitat loss and direct killing for bushmeat markets. It may have evolved to . There are only seven vertebrae in mammal necks, meaning that the giraffe has vertebrae that are nearly a foot long each! [10] They also feed on shrubs, grass and fruit. In the Sahel, the need for firewood and grazing room for livestock has led to deforestation. [42] The upper jaw has a grooved palate and lacks front teeth. Such interactions between males have been found to be more frequent than heterosexual coupling. A giraffe's neck alone is 6 feet (1.8 meters) long and weighs about 600 lbs. [34] This giraffe has large dark patches that usually have complete margins, but may also have sharp edges. [50]:27, The front and back legs of a giraffe are about the same length. [72] It has also been proposed that the neck serves to give the animal greater vigilance. A giraffe's neck alone is 6 feet (1.8 meters) long and weighs about 600 lbs. [87] In general, females are more selective than males in who they associate with in regards to individuals of the same sex. [42], Giraffes are usually found in groups that vary in size and composition according to ecological, anthropogenic, temporal, and social factors. Giraffes have seven cervical vertebrae, but each one can be about 10 inches long. The giraffe's chief distinguishing characteristics are its extremely long neck and legs, its horn-like ossicones, and its distinctive coat patterns.It is classified under the family Giraffidae, along with its closest extant relative, the okapi.Its scattered range extends from Chad in the north to South Africa in the south, and from Niger in the west to Somalia in the east. It is traditionally considered to be one species, Giraffa camelopardalis, with nine subspecies.
