camel dulla anatomy

This camel has a quick rate of rehydration and can drink at 10–20 L (2.2–4.4 imp gal) per minute. [67], The hump stores up to 80 lb (36 kg) of fat, which the camel can break down into energy to meet its needs when resources are scarce; the hump also helps dissipate body heat. [54] In another study, dromedaries were found to have natural antibodies against the rinderpest and ovine rinderpest viruses. Why should there be an explanation? [50] Dromedaries under the age of two years have a fine undercoat that tends to fall off and should be cropped by hand. To attract females they extrude their soft palate – a trait unique to the dromedary. While a role in courtship looks likely, the precise role of the Mongolian gazelle's PPP remains undetermined. The chest should be deep and the hump should be well-developed with sufficient space behind it to accommodate the saddle. [17], Camels have a slow growth rate and reach sexual maturity slower than sheep or goat. Harry was ill-tempered but was included in an expedition the following year because he could carry heavy loads. A report on three Arabian Gulf Countries", https://en.wikipedia.org/w/index.php?title=Dromedary&oldid=996005073#Characteristics, Articles containing Ancient Greek (to 1453)-language text, Беларуская (тарашкевіца)‎, Srpskohrvatski / српскохрватски, Creative Commons Attribution-ShareAlike License. [60] The dromedary can conserve water by reducing perspiration by fluctuating the body temperature throughout the day from 31 to 41.7 Â°C (87.8 to 107.1 Â°F). [14] Riding camels of Arabia, Egypt and the Sahara are locally known as the Dilool, the Hageen, and the Mehara respectively; several local breeds are included within these groups. Surgical removal of the dhula is recommended in such cases, and the animals soon recover. At rest, the pouch hangs down from the soft palate, lying between the root of the tongue and the epiglottis, between the two halves of the hyoid apparatus (Frey & Gebler 2003). [125], The meat of a five-year-old dromedary has a typical composition of 76% water, 22% protein, 1% fat, and 1% ash. Some fish produce sounds that are amplified in their gas sac, but I don't think anyone has suggested that 'vocalization' is the primary function of the gas sac. [113] At first the camel's head is controlled, and it is later trained to respond to sitting and standing commands, and to allow mounting. I wonder if there is any indication of a dhula in the embryonic development in the Bactrian. And it also possesses enlarged, paired laryngeal ventricles (if you need a reminder on the terminology, do go check the first article in the pouches, pockets and sacs series). thus the name. The main symptoms are recurring fever, anaemia and weakness; the disease is typically fatal for the camel. The dromedary may also graze on tall, young, succulent grasses. Brown (Oxford), pp. 4. [103] India has a dromedary population of less than one million, with most (0.67 million) in the state of Rajasthan. Inside Nature's Giants: polar bear special, Guest Post: Shooting the Stars on a Budget. Phylogenetic relationships of the dromedary from combined analysis of all molecular data. Privacy statement. The male dromedary camel has an organ called a dulla in its throat, a large, inflatable sac he extrudes from his mouth when in rut to assert dominance and attract females. Veterinary World 3, 473-475. [123] A special factory has been set up in Nouakchott to pasteurise and make cheese from camel milk. Such a strange structure to develop. Looking forward to the tapir post! Well, time to look at it again. [56] A 2013–14 study of dromedaries in Saudi Arabia concluded the unusual genetic stability of MERS-CoV coupled with its high seroprevalence in the dromedary makes this camel a highly probable host for the virus. -Walt Whitman They use their lips to grasp the food and chew each bite 40 to 50 times. The major fatty acids in the meat were palmitic acid (26.0%), oleic acid (18.9%) and linoleic acid (12.1%). The terminology used in case of males is “Thoot”, “Rutt” or “Musth”. Pouches, pockets and sacs in the heads, necks and chests of mammals, part III: baleen whales, Pouches, pockets and sacs in the heads, necks and chests of mammals, part IV: reindeer and a whole slew of others, Dammit, and I sooo loved the 'necks for sex' hypothesis, Pronghorn, "designed by committee" (pronghorns part I), Release the fossil pronghorns!! The mating season lasts three to five months, but may last a year for older animals. Even without the possible presence of a dhula, Bactrian camels already do weird displays: the males soak their long tails with urine and perform a distinctive tail-flapping display; they also squat and make roaring noises. Hornbills, hoopoes and woodhoopoes are all similar in appearance and have been classified together in a group termed Bucerotes. The dromedary has been used in warfare since the 2nd century BC. Zoologischer Anzeiger - A Journal of Comparative Zoology 242, 33-62. Again, this was surgically removed and the camel rapidly returned to health. Absent some sort of ineluctable developmental constraint (of the type that gives male mammals vestigial nipples, e.g. [76], A single calf is born after a gestation period of 15 months. This work was aimed to study the camel particular diverticulum of the soft palate "Dulla" in order to understand the processus of its oral exteriorisation in the adult males. [116] The quantities of sodium, potassium, zinc, iron, copper, manganese, niacin and vitamin C were relatively higher than the amounts in cow milk. The uterus is bicornuate. [17] Though the preparation of butter from dromedary milk is difficult, it is produced in small amounts by nomads, optimized at 22.5% fat in the cream. [24], The modern dromedary probably evolved in the hotter, arid regions of western Asia from the Bactrian camel, which in turn was closely related to the earliest Old World camels. [126] A study of the meat of Iranian dromedaries showed its high glycogen content, which makes it taste sweet like horse meat. This period marked the successful radiation of the Camelus species, which migrated over the Bering Strait and dispersed widely into Asia, eastern Europe and Africa. These include Aristida pungens, Acacia tortilis, Panicum turgidum, Launaea arborescens and Balanites aegyptiaca. This links us nicely to the select group of mammals - perissodactyls, hyraxes, bats and…, I've mentioned laryngeal and tracheal anatomy a few times on Tet Zoo (see the links at the very bottom for more). Hybrids from other combinations tend to be bad-tempered or runts. [99][101], In Asia, nearly 70% of the population occurs in India and Pakistan. However, the levels of thiamin, riboflavin, folacin, vitamin B12, pantothenic acid, vitamin A, lysine, and tryptophan were lower than those in cow milk. An extinct species of camel [10] in the separate genus Camelops, known as C. hesternus, [11] lived in western North America until the end of the Pleistocene, roughly 11,000 years ago.. It's then cut away with surgical tools, and any large blood vessels (often present at the base of the dhula) are cauterised (Kuhad et al. As with the palatinal pharyngeal pouch, a precise role for the enlarged ventricles has yet to be demonstrated, but it has been inferred that - like the enlarged ventricles of some primates - they act as resonating chambers used during vocalisation [image below - from Frey & Gebler (2003) - shows internal cranial anatomy of a male Mongolian gazelle. Climatic factors would seem like an insufficient explanation, given that a 'dhula' is also present in the Mongolian gazelle (which has a natural distribution and habitat preferences roughly similar to those of the wild Bactrian camel). Etimologio. [2][4] The first recorded use in English of the name "dromedary" occurred in the 14th century. In a study to find whether young could exist on milk substitutes, two male, month-old camels were separated from their mothers and were fed on milk substitutes prepared commercially for lambs, and they grew to normal weights for male calves after 30 days. [28], The ideal riding camel is strong, slender and long-legged with thin, supple skin. This really is the end. [55], In 2013, a seroepidemiological study (a study investigating the patterns, causes and effects of a disease on a specific population on the basis of serologic tests) in Egypt was the first to show the dromedary might be a host for the Middle East respiratory syndrome coronavirus (MERS-CoV). He estimated a speed of 14–19 km/h (8.7–11.8 mph) during a fast run, by observing northern African and Arabian dromedaries. [17] Males become aggressive in the mating season, and sometimes wrestle. The protrusion of the dulla occurs at an interval of 5 to 30 min and is accompanied by a loud gurgling/roaring sound. A note on the sexual behavior of the male camel (Camelus dromedarius). Males try to defeat other males by biting the opponent's legs and taking the head between his jaws. Dromedary slaughter is more difficult than the slaughter of other domestic livestock such as cattle because of the size of the animal and the significant manual work involved. Prolapse of the soft palate in a male Arabian camel (Camelus dromidarius [sic]). Many thanks to Mark Evans of the New Walk Museum, Leicester, for this photograph of yet another camel skeleton, this one from the MNHN in Paris, France: This is especially interesting because it's our first Bactrian camel -- the Cambridge Camel and the Oxford camel are both dromedaries. [5] The dromedary possibly originated in Arabia or Somalia and is therefore sometimes referred to as the Arabian or East African camel. [14] According to Richard Bulliet, they can be used for a wide variety of purposes: riding, transport, ploughing, and trading and as a source of milk, meat, wool and leather. Goodbye Tet Zoo ver 2. [52][92] The popularity of dromedaries increased after the Islamic conquest of North Africa. What you may not have known is that Rich is not…, Pouches, pockets and sacs in the heads, necks and chests of mammals, part V: palatal (and other) pouches in camels and gazelles. Semieka, M. A. [112], The ideal age to start training dromedaries for riding is three years,[40] although they may be stubborn and unruly. [1]Camel is also used more broadly to describe any of the six camel-like creatures in the family camelidae: the two true camels, and the four South American camelids: the llama, alpaca, guanaco, and vicuña. [28] At this stage a camel will often try to escape when a trainer tries to mount it. The distinctive features are its long, curved neck, narrow chest and single hump (the Bactrian camel has two), thick, double-layered eyelashes and bushy eyebrows. [17], Special behavioral features of the dromedary include snapping at others without biting them and showing displeasure by stamping their feet. Cameron, John is being rude and employing phallus-based humour :). All teeth are in use by 8 years. [82] The carcass, weighing 141–310 kg (311–683 lb) for a five-year-old dromedary,[82] is composed of nearly 57% muscle, 26% bone and 17% fat. [121] In 2001, the ability of dromedary milk to form curd was studied; coagulation did not show curd formation, and had a pH of 4.4. Check out this video of a camel extending its dulla! Camelmen often aid the male insert his penis into the female's vulva. there's a large and very rich literature on [...] pathologies caused by camels. lately, we've recently been quite taken with their necks. Just such an image is included in Reese & Chawla (2001): I decided against using it here, but did plan to (email me if you want the pdf). [124] Mystical beliefs surround the use of camel milk in some places; for example, it may be used as an aphrodisiac in Ethiopia. Camel is a seasonal breeder and their reproduction is different as compared to other livestock as both male and female come into heat during the breeding season. [14] At the peak of lactation, a healthy female would typically provide 9 kg (20 lb) milk per day. Leg opening: Camel splays hind legs until they form an angle of at least 45 degrees. [19] For about a thousand years, Bactrian camels and dromedaries have been successfully bred in regions where they are sympatric to form hybrids with either a long, slightly lopsided hump or two humps – one small and one large. [113] The camel is not easily exhausted unless diseased or undernourished, and has remarkable endurance and hardiness. 2 vols. Anatomy and mechanism of distension of the dulaa of the one-humped camel. [107] It is particularly prized for its capability to outrun horses in the deserts. In order to improve the racing efficiency of male camels, their dhulas are sometimes surgically removed in an operation termed a soft palatectomy. & Knospe, C. 2010. I've been in Romania and Hungary where I had a great time - saw lots of neat animals (fossil and living) and hung out with some neat people. Kamal, A. M. 2008. Catastrophic prolapse of the dhula has sometimes been reported, and the result is totally grotesque: imagine a foot-long, mangled, dangling organ, dripping with snot, mucus and blood and hanging heavily down well below the head, with a lumpy, red and purple viscous surface. In Brown, K. (ed) Encyclopedia of Language and Linguistics. [109] An account by Aurelian also cited that, in her escape to Euphrates, Zenobia used a dromedary to outrun her pursuers after she was defeated at Palmyra. The last four articles that have appeared here were all scheduled to publish in my absence. Arising from the posterolateral side of the me­dulla behind the auditory nerve it runs anteromedially between the external and inter­nal carotid arteries. [97][98], In the early 21st century, the domesticated dromedary is found in the semi-arid to arid regions of the Old World. Given my palaeontological bent, one of the first things I thought about when considering the dhula is whether it might have been present in various fossil camelids - after all, the thought of a scene where a group of Gigantocamelus are displaying their dhulas and flopping frothy saliva all over the place is quite exciting :) However, it is specifically stated in the literature that the structure is unique to the Dromedary and that there is no indication of its presence in the Bactrian camel: e.g., "It is not seen in any other mammal, even close relatives like the Bactrian camel or South American Llama" (Kuhad et al. [47] They are enclosed in a conical bursa and have the dimensions 4×2.5×0.5 cm (1.57×0.98×0.20 in) during anestrus. [14] The next stage involves training it to respond to reins. [62] Camels scratch parts of their bodies with their legs or with their lower incisors. The Sahel marks the southern extreme of its range, where the annual rainfall is around 550 mm (22 in). As the animal ages, the meat grows tougher and deteriorates in taste and quality. [27][41] Females have cone-shaped, four-chambered mammary glands that are 2.4 cm (0.94 in) long with a base diameter of 1.5 cm (0.59 in). The bits we're interested in are Burs pal. I dag i historien: 4. juni 1855 er kameler blevet brugt som byrder af byrder i årtusinder, og skabelsen er på mange måder langt mere velegnet til opgaven end endog den mest robuste af equids. It is the tallest of the three species of camel; adult males stand 1.8–2 m (5.9–6.6 ft) at the shoulder, while females are 1.7–1.9 m (5.6–6.2 ft) tall. Pouches, pockets and sacs in the heads, necks and chests of mammals, part II: elephants have a pouch in the throat... or do they? I'm sorry, but the picture of a dissected dhula makes my stomach churn :(. With a large palatinal pharyngeal pouch, paired tympanic pharyngeal pouches, paired, internally chambered, enlarged laryngeal ventricles, and a descended larynx, the Mongolian gazelle is - I think you'll agree - a pretty remarkable artiodactyl. [111] The camels of the Bejas of Sudan and the Hedareb, Bilen, and the Tigre people of Eritrea[92] and the Anafi camel bred in Sudan are common breeds used as riding camels. The hybrid camel, a hybrid between Bactrian and dromedary camels, has one hump, though it has an indentation 4–12 cm (1.6–4.7 in) deep that divides the front from the back.The hybrid is 2.15 m (7 ft 1 in) at the shoulder and 2.32 m (7 ft 7 in) tall at the hump. 1998) [the photo below, from Kuhad et al. ArnautoviÄ I, & Abdel Magid AM (1974). Studies Show Chewing Gum Can Help, Vitamin D Linked To Autism Spectrum Disorder, Evidence for a massive paleo-tsunami at ancient Tel Dor, Israel, Children's emotion inferences from masked faces during the COVID-19 pandemic, VR simulations shed potential light on goalkeepers' ability to stop free kicks, Capturing 40 years of climate change for an endangered Montana prairie, Remarkable new species of snake found hidden in a biodiversity collection. LOL. Because much of Zeren courtship and mating behaviour occurs at night, observations are few, and it remains uncertain whether these gazelles extend their PPPs from out of their mouths. The Horn of Africa has nearly 35% of the world's dromedaries;[88] most of the region's stock is in Somalia, followed by Sudan, Eritrea, and Ethiopia (as of the early 2000s). There was rapturous applause, swooning, the delight of millions. The hybrid camel, a hybrid between Bactrian and dromedary camels, has one hump, though it has an indentation 4–12 cm (1.6–4.7 in) deep that divides the front from the back.The hybrid is 2.15 m (7 ft 1 in) at the shoulder and 2.32 m (7 ft 7 in) tall at the hump. [71] In case of starvation, they can even eat fish and bones, and drink brackish and salty water. [81] Oestrus may be cued by the nutritional status of the camel and the length of day. [14], CS1 maint: multiple names: authors list (, Middle East respiratory syndrome coronavirus, Centers for Disease Control and Prevention, "A complete mitochondrial genome sequence of the wild two-humped camel (, International Livestock Centre for Africa, "A Frameshift Mutation in KIT is Associated with White Spotting in the Arabian Camel", "Cranial capacity of Indian camel. But then I read this: it specifically refers to the presence of a dhula in Bactrian camels! [14] Camel meat is often eaten by African camel herders, who use it only during severe food scarcity or for rituals. It is important for several Bedouin pastoralist tribes of northern Arabia, such as the Ruwallah, the Rashaida, the Bani Sakhr and the Mutayr. In the Persian Gulf region the dromedary is locally classified into breeds including Al-Majahem, Al-Hamrah, Al-Safrah, Al-Zarkah and Al-Shakha, based on coat colour. [14], The dromedary is prone to trypanosomiasis, a disease caused by a parasite transmitted by the tsetse fly. [129] Though less affected by mishandling than other livestock, the pre-slaughter handling of the dromedary plays a crucial role in determining the quality of meat obtained; mishandling can often disfigure the hump. [17] The dromedary has long, powerful legs with two toes on each foot. Nevertheless, it seems to me odd to start looking for an explanation in the absence of any good reason to assume there's anything to explain in the first place. [49], The dromedary generally suffers from fewer diseases than other domestic livestock such as goats and cattle. [118] Milk yield varies geographically and depends upon the animals' diet and living conditions. [23] Leese estimated a lactating female would yield 4 to 9 L (0.88 to 1.98 imp gal) besides the amount ingested by the calf. Looking back at it now, that very first ver 2 post is rather odd. [127] In a study of the fatty acid composition of raw meat taken from the hind legs of seven one-to-three years old males, 51.5% of the fatty acids were saturated, 29.9% mono-unsaturated, and 18.6% polyunsaturated. We are part of Science 2.0, a science education nonprofit operating under Section 501(c)(3) of the Internal Revenue Code. The scrotal skin tends to … These camels were well-suited to long desert journeys and could carry a great deal of cargo, allowing substantial trans-Saharan trade for the first time. The bushy eyebrows and the double row of eyelashes prevent sand and dust from entering the eyes during strong windstorms, and shield them from the sun's glare. [31], Compared with the Bactrian camel, the dromedary has a lighter build, longer limbs, shorter hairs, a harder palate and an insignificant or absent ethmoidal fissure. The Veterinary Record 149, 656-657. It's on the blood-feeding behaviour of…, So sorry for the very short notice. A superficially similar structure to the dhula - the palatinal pharyngeal pouch (PPP) - is present in the Mongolian gazelle or Zeren Procapra gutturosa [shown below, from here... though that lump in the throat is not the PPP: read on]. [108] Record of its use during the time of Alexander the Great indicate that the animal could cover up to 50 miles per day for a week and they could go for up to a month without water. The Veterinary Record 149, 656-657. might the dhula be an odd example of the Handicap principle? Prior to semen collection, male camels were exposed to a sexually receptive female for a period of 10 min, after which the camel was allowed to approach and mount a female camel restrained in sternal recumbency. [102] According to the FAO, the dromedary population in six countries of the Persian Gulf was nearly 0.67 million in 2003. [23] This hypothesis is supported by the fact that the dromedary foetus has two humps, while in the adult male an anterior vestigial hump is present. The next major group of camels were imported into Australia in 1860, and between 1860 and 1907 10 to 12 thousand were imported. The dhula is present in females, but is apparently never used. And might the dhula be an odd example of the Handicap principle? [27], The coat is generally brown but can range from black to nearly white. Biology. 3. Rutting males may develop nausea. [65] Dromedaries keep their mouths open while chewing thorny food. [35] The front feet are 19 cm (7.5 in) wide and 18 cm (7.1 in) long; they are larger than the hind feet, which measure 17 cm (6.7 in) wide and 16 cm (6.3 in) long. Clarendon press, Oxford, 1987:113-114. [93][94] In Libya, dromedaries were used for transport and their milk and meat constituted the local diet. [51] Nervous camels may vomit if they are carelessly handled; this does not always indicate a disorder. phar. Production of vocalizations in mammals. [129] The dressing percentage – the percentage of the mass of the animal that forms the carcass – is 55–70%,[82] more than the 45–50% of cattle. The combined population of the dromedary and the Bactrian camel decreased by around 21% between 1994 and 2004. [14] However, a 1994 analysis of the mitochondrial cytochrome b gene showed the species display 10.3% divergence in their sequences. [29] The hair is long and concentrated on the throat, shoulders and the hump. [12] A full-grown adult camel stands 1.85 m (6 ft 1 in) at the shoulder and 2.15 m (7 ft 1 in) at the hump. In Australia, short-term home ranges of feral dromedaries cover 50 to 150 km2 (19 to 58 sq mi); annual home ranges can spread over several thousand square kilometres. In order to improve the racing efficiency of male camels, their dhulas are sometimes surgically removed in an operation termed a soft palatectomy. Some fish produce sounds that are amplified in their gas sac, but I don't think anyone has suggested that 'vocalization' is the primary function of the gas sac. The night is mainly spent resting. The hybrid camel, a hybrid between Bactrian and dromedary camels, has one hump, though it has an indentation 4–12 cm (1.6–4.7 in) deep that divides the front from the back.The hybrid is 2.15 m (7 ft 1 in) at the shoulder and 2.32 m (7 ft 7 in) tall at the hump. tymp. An ineluctable developmental constraint, then? Inside Nature's Giants: a major television event worthy of praise and accolade. Essentially we'd be locking at two "evolutionary events" rather than one. Camel is a seasonal breeder and their reproduction is different as compared to other livestock as both male and female come into heat during the breeding season. A 1980 study showed androgen levels in males influences their behavior. [61] Herds may congregate to form associations of hundreds of camels during migrations at the time of natural disasters. But, as some commenters have said above, the presence of a weird sexually-selected display structure is consistent with its uniqueness to one species and absence in a sister-species. bladder: a membranous sac or organ serving as a receptacle for a fluid or air. Journal of Anatomy 203, 451-471. Has any hypothesis been offered for the (apparent) absence of this structure in the Bactrian camel? This isn't a difficult operation: the camel is restrained and tranquilised, the dhula is grasped with forceps and spread out to maximum extent. [50] Temperature fluctuations occur throughout the day in a healthy dromedary – the temperature falls to its minimum at dawn, rises until sunset and falls during the night. [126] A seven-to-eight-year-old camel can produce a carcass of 125–400 kg (276–882 lb). To see new stuff (from July 2011 to present), click here. [63] A study said the typical diet of the dromedary is dwarf shrubs (47.5%), trees (29.9%), grasses (11.2%), other herbs (0.2%) and vines (11%). It and the external nasal air sac of some seals seem unrelated to a buoyancy function more common in animals with internal air sacs. [75] As the male gurgles, copious quantities of saliva turns to foam and covers the mouth. Last week, we kicked off our very first Messier Monday by spotlighting M1: the Crab Nebula. The males of the herd prevent female members from interacting with bachelor males by standing or walking between them and sometimes driving the bachelor males away. [42] These glands can produce milk with up to 90% water content even if the mother is at risk of dehydration. [40] Copulation begins with foreplay; the male smells the female's genitalia and often bites her there or around her hump. [99] Most of the Australian feral camels are dromedaries, with only a few Bactrian camels. [20], The extinct Protylopus, which occurred in North America during the upper Eocene, is the oldest and the smallest-known camel. The word camel comes from the Arabic word , gml , which has the literal meaning, beauty . It consists of 11.7% solids, 3% protein, 3.6% fat, 0.8% ash, 4.4% lactose and 0.13% acidity (pH 6.5). Mina, Abu Dhabi, 1997. [17], The dromedary is specially adapted to its desert habitat; these adaptations are aimed at conserving water and regulating body temperature. Khan AA, Kohli IS. [14] It may be used for ploughing in pairs or in groups with buffaloes or bullocks. -Ptolemy and During rutting the Dulla enlarges on filling with air from the trachea until it hangs out of the mouth of the camel and comes to resemble a pink ball. If the thing's unique to the dromedary, it's likely an innovation in than particular lineage. Contributions are fully tax-deductible. [52] Brucellosis is another prominent malady. The oviducts are 25–28 cm (9.8–11.0 in) long. [23], Camel milk is a staple food of nomadic tribes living in deserts. You can also shop using Amazon Smile and though you pay nothing more we get a tiny something. The dhula as a vestige of a split upper lip, involved in salivation, and secondarily as a male display device (advertizing ability to salivate thus eat very dry herbage) sounds correct. Males typically weigh between 400 and 600 kg (880 and 1,320 lb), and females … [40] Leese described two types of saddles generally used in camel riding: the Arabian markloofa used by single riders and the Indian pakra used when two riders mount the same camel. Relatively little known is that (some) camels possess an inflatable diverticulum on the palate, termed the dhula, dulaa, gulah, goola, qulla or pálu, and known technically as the vesica palatina or palatine diverticulum. The dromedary (Camelus dromedarius) (/ ˈ d r ɒ m ə d ɛ r i / or /-ə d r i /), also called the Arabian camel, is a large even-toed ungulate, of the genus camelus, with one hump on its back. The male dromedary camel has in its throat an organ called a dulla and it resembles a long, swollen, pink tongue hanging out of the side of its mouth. (palatinal pharyngeal pouch) and Burs. Last time we looked at the laryngeal sacs of primates (and, should you encounter unfamiliar anatomical terms in the following text, be sure to check out that first…, Back to the series on pouches, pockets and sacs (for previous articles see links below). Research Journal of Veterinary Sciences 1, 16-27.
