En zo erg zijn de meeste niet. Op school heb ik het nog nooit gehoord volgens mij. Wij gingen in de 4e met school naar Nijmegen en daar was ook een andere school uit het noorden ergens, en die vonden blijkbaar dat ik vreemd praat.

Ik praat natuurlijk ook wel anders dan zij, maar ik praat van mijn vriendinnen nog wel het meest ABN zeg maar, dus ik denk dat er gewoon altijd mensen zijn die gaan zeuren dat je 'anders' klinkt Ik ga waarschijnlijk na dit jaar in Nijmegen studeren, dus dan wordt het sowieso wel minder denk ik Maar sommige dingen blijf je waarschijnlijk altijd doen, en dat vind ik ook niet uitmaken.

They then lie on the nest while the eggs are incubating, but there is no evidence of any parental care once the eggs hatch. Although Varanus komodoensis can see meters away and can hear a restricted range of sound, its sense of smell is its primary method for detecting food and the tip of its tongue is its primary scent detector.

Males communicate dominance in mating and feeding order by wrestling in upright positions. Females give off a scent in their feces to communicate that they are ready to mate and the male replies by rubbing his chin on her and licking her body.

Komodo dragons are currently classified as endangered throughout their range. This status is the result of a combination of prey depletion, poaching, and habitat encroachment by humans.

Varanus komodoensis hatches from eggs. Young Komodo dragons live in trees to avoid falling prey to older members of the species.

They are also much smaller and more sinuous than the adults, allowing them to live in trees. At 8 months, they grow too large to be arboreal, alter their diet, and become terrestrial.

Varanus komodoensis individuals have been known to attack and kill humans in a few rare occurrences.

They also have attacked and harmed livestock in the area. Komodo dragons are an important ecotourism draw. Scientists are also conducting studies on how they are able have strains of lethal bacteria living in their saliva without being affected by them.

Varanus komodoensis is a top predator in its habitat and one of the largest animals present in the area.

It is also a scavenger that eats recently dead animals and removes them from the landscape. A normal adult Komodo dragon diet consists mainly of carrion, but it is not uncommon for them to attack and eat a variety of large prey, including goats, pigs, deer, wild boar, horses, water buffalo, and smaller Komodo dragons.

Komodo dragons hunt larger prey by ambushing them and delivering a bite. They then follow the injured animal until they succumb to either blood loss or infection.

The saliva of Komodo dragons is rich in bacteria that rapidly leads to infection in their prey. A recent discovery of venom in the bites of Varanus species implies that venoms may be used in subduing prey also, although specific research on Komodo dragon venom action has not been completed.

Juveniles feed on grasshoppers, beetles, small geckos, eggs, birds, and eventually small mammals. Varanus komodoensis is able to swallow large pieces of food by expanding its throat and its flexible skull.

They eat most of their prey, leaving very little to be wasted. Varanus komodoensis is found only in the lesser Sunda region of the Indonesian archipelago, including the islands of Komodo, Flores, Rinca, and Padar.

Adult Komodo dragons live mainly in tropical savannah forests. They prefer open lowland areas with tall grasses and bushes, but are also found in other habitats, such as beaches, ridge tops, and dry riverbeds.

Young Komodo dragons are arboreal and live in forested regions until they are eight months old. Although many Varanus komodoensis individuals fall prey to other animals as hatchlings, ones that live to adulthood usually have a lifespan of around 50 years.

Average lifespan Sex: female Status: captivity : 8. Komodo dragons are the largest lizards, reaching kg and greater than three meters in length.

Juveniles are green with yellow and black bands. Adults dull and uniform in color, from brown to grayish red.

Their robust bodies are uniformly covered in rough scales. They have strong limbs and a powerful, muscular tail. The heads of Komodo dragons have a rounded snout and ear openings.

Their skulls are flexible and have sharp, serrated teeth. Although males tend to grow larger, there are no obvious morphological differences between the sexes.

Adult Komodo dragons are at the top of their food chain and do not have any predators. Juveniles often fall prey to adults, larger mammals, and birds.

They avoid predation by being arboreal until they become larger. Coming in a variety of colors, such as blue, orange, green, and gray, the Komodo dragon is the largest extant lizard species.

Male individuals can weigh up to kg, and can grow up to 3 m 10 feet in length. The largest individual ever recorded was 3.

Female individuals are smaller, usually only about 1. Aside from the obvious size difference, there are no major morphological differences between the sexes National Geographic.

Despite their impressive size, they are very small when born, about 0. The body of the lizard is long and flat, with short bowed legs. At the end of each leg are long sharp claws, which are used for both hunting and digging nests.

The tail of the Komodo dragon is long and powerful Smithsonian National Zoological Park. While being impressive in size, the most interesting aspect of the Komodo dragon is its mouth.

This dragon has a dorsoventrally flattened rostrum, which means it has a long, flat snout and its mouth is filled with long, curved and serrated teeth.

The jaw contains several movable joints, such as the intramandibular hinge, which allows the Komodo dragon to open its mouth very wide, and quickly swallow its food Smithsonian National Zoological Park.

Despite its intimidating mouth, the Komodo dragon has a relatively weak bite force compared to other large predators e. Located within the mandible are glands that secrete powerful venom.

This venom acts as both a neurotoxin and an anti-coagulant Fry et al, The neurotoxin causes the prey to go into shock, which allows the dragon to rest after hunting without fear of the prey escaping.

The anti-coagulant effect will cause the animal to bleed out very quickly, should it manage to escape. The effects of biting and pulling on the forces generated during feeding in the Komodo dragon Varanus komodoensis.

Proc Natl Acad Sci National Geographic. Komodo Dragon. Retrieved on 14 Apr. The sexual maturation of both male and female komodo dragons typically occurs between 5 and 7 years of age.

A typical komodo dragon mating season occurs between May and August. Dominant males often engage in wrestling matches in an upright position, balancing on their tails and hind legs in order to determine courtship over a female.

Stimulation is both palpable and chemical, through skin gland secretions. A typical Komodo dragon gestation period will last around 9 months. Subsequently, a komodo dragon will lay anywhere between eggs in September Ciofi, Females will lie on the nests to protect their potential offspring, but they do not care for them after they hatch.

In fact, as soon as they hatch, the young will scatter and climb up trees in order to avoid being cannibalized by the mother or other dragons.

The hatchlings will weigh less than 3. They will feed on a diverse diet of insects, small lizards, snakes, and birds.

If they make it to five years of age, their chance of survival increases dramatically. This has been observed both in the wild and in captivity. This means that Komodo dragons can reproduce asexually as well as sexually Yam, This trait has been observed in varying species of reptiles.

Parthenogenesis is extremely rare among vertebrates, occurring in a mere 0. Furthermore, Komodo dragons have a unique variation in their sex determination.

The presence of two identical sex chromosomes results in a male komodo dragon, while two different ones results in a female.

Komodo dragon gender is determined by incubation temperature. Researchers speculate that this ability enabled female Komodo dragons to establish new colonies when washed up alone on neighboring shores during storms Yam, References Ciofi, C.

The Komodo Dragon. Scientific American 3 Smithsonian National Zoological Park. Strange but true: Komodo dragons show that "virgin births" are possible.

Scientific American, 28 Dec. Komodo dragons are solitary animals that generally meet only to reproduce and eat. They are primarily diurnal, which means they are most active during the day.

They tend to be most active during the wet season. Komodo dragons prefer hot and dry places with open grassland, as well as tropical forests at low elevations.

In regards to territorial behavior, there is a dominance hierarchy determined by size and sex. The largest and strongest males get first priority when eating.

Males often wrestle in an upright position to determine mating and feeding orders. Hissing is a common vocalization that indicates defensive behavior and is often used during feeding, fighting, and repeatedly by females during mating season San Diego Zoo, Additionally, the feces of a female komodo dragon emits pheromones that alert the males that they are ready to mate.

Komodo dragons are quadrupeds and possess the ability to sprint briefly at speeds of up to 20 kph. As a result, its hunting strategy relies primarily on strength and stealth.

It is common for them to spend hours in a single spot, waiting for a deer, boar, goat, or other potential prey Smithsonian National Zoological Park.

Komodo dragons act as both predators and scavengers. They have venomous glands packed with toxins that lower blood pressure, cause massive bleeding, prevent clotting and induce shock in prey National Geographic.

Young komodo dragons are exceptional tree climbers, but they tend to lose this ability after a year. It is primarily a defense mechanism to avoid being cannibalized by their mother.

As Komodo dragons mature, they begin to transition into a semi-aquatic lifestyle. When hunting, komodo dragons rely heavily on their sense of smell for finding food.

This is utilized through scent-detecting glands at the tips of their tongues Smithsonian National Zoological Park.

Reference San Diego Zoo Global. The Komodo dragon is found only on 5 islands in the lesser Sundas region of southeastern Indonesia, including Komodo, Rinca, Gili Motang, Gili Dasami, and Flores Jessop et al, ; San Diego Zoo, These islands are volcanic in origin, and covered in many habitat types, but mainly forest and savannah.

Most of the Komodo dragons live on Komodo Island, from which their name is derived Jessop et al, The temperatures during the daytime in the dry season can reach up to 35 degrees Celsius.

In addition to these high temperatures, the islands can reach up to 70 percent humidity San Diego Zoo, Komodo dragons live in three main habitat types: coastal mangroves, open savannahs, and fragmented shade forests.

Juveniles are typically arboreal, while adult dragons typically are terrestrial Harlow et al, Most komodo dragons prefer to live in savannahs with tall grasses and bushes, where they wait to ambush prey, but they are found all across the islands.

Other types of habitats they can be found in are beaches and mountaintops. Within their habitats, Komodo dragons build themselves one of three types of nests for living and egg-laying: ground nests, hill nests, or mound nests.

Ground nests are deep burrows that are horizontal to the ground. Hill nests are large burrows built into the face of a hill, in one or more tiers.

Mound nests are nests that were previously used by other animals such as orange-footed scrub fowl or other dragons that have been repurposed by Komodo dragons.

These nests tend to be constructed more often within a fragmented deciduous forest than any other type of habitat Jessop et al, Upon hatching, komodo dragons are arboreal until about 8 months of age.

After 8 months of age, they leave the trees for the ground where they spend most of their time, although they are also excellent swimmers National Geographic.

References Harlow, H. Body temperature and thermoregulation of Komodo dragons in the field. Journal of Thermal Biology, 35 7 , — Jessop, T. Distribution, use and selection of nest type by Komodo dragons.

Biological Conservation, 5 , — Retrieved 14 Apr. The Komodo dragon [4] Varanus komodoensis , also known as the Komodo monitor , is a species of lizard found in the Indonesian islands of Komodo , Rinca , Flores , and Gili Motang.

Its unusually large size has been attributed to island gigantism , since no other carnivorous animals fill the niche on the islands where it lives.

As a result of their size, these lizards dominate the ecosystems in which they live. It has been claimed that they have a venomous bite; there are two glands in the lower jaw which secrete several toxic proteins.

The biological significance of these proteins is disputed, but the glands have been shown to secrete an anticoagulant. Komodo dragons' group behaviour in hunting is exceptional in the reptile world.

The diet of big Komodo dragons mainly consists of Timor deer , though they also eat considerable amounts of carrion.

Mating begins between May and August, and the eggs are laid in September; as many as 20 eggs are deposited at a time in an abandoned megapode nest or in a self-dug nesting hole.

Young Komodo dragons are vulnerable and therefore dwell in trees, safe from predators and cannibalistic adults. They take 8 to 9 years to mature, and are estimated to live up to 30 years.

Komodo dragons were first recorded by Western scientists in In the wild, their range has contracted due to human activities, and they are listed as vulnerable by the IUCN.

Komodo dragons were first documented by Europeans in , when rumors of a "land crocodile" reached Lieutenant van Steyn van Hensbroek of the Dutch colonial administration.

Douglas Burden in After returning with 12 preserved specimens and two live ones, this expedition provided the inspiration for the movie King Kong.

The Dutch, realizing the limited number of individuals in the wild, soon outlawed sport hunting and heavily limited the number of individuals taken for scientific study.

Collecting expeditions ground to a halt with the occurrence of World War II, not resuming until the s and s, when studies examined the Komodo dragon's feeding behavior, reproduction, and body temperature.

At around this time, an expedition was planned in which a long-term study of the Komodo dragon would be undertaken. This task was given to the Auffenberg family, who stayed on Komodo Island for 11 months in During their stay, Walter Auffenberg and his assistant Putra Sastrawan captured and tagged more than 50 Komodo dragons.

The Komodo dragon is also sometimes known as the Komodo monitor or the Komodo Island monitor in scientific literature, [4] although this name is uncommon.

The evolutionary development of the Komodo dragon started with the genus Varanus , which originated in Asia about 40 million years ago and migrated to Australia , where it evolved into giant forms the largest of all being the recently extinct Megalania , helped by the absence of competing placental carnivorans.

Around 15 million years ago, a collision between the continental landmasses of Australia and Southeast Asia allowed these larger varanids to move back into what is now the Indonesian archipelago, extending their range as far east as the island of Timor.

The Komodo dragon is believed to have differentiated from its Australian ancestors about 4 million years ago. However, recent fossil evidence from Queensland suggests the Komodo dragon actually evolved in Australia before spreading to Indonesia.

Genetic analysis of mitochondrial DNA shows the Komodo dragon to be the closest relative sister taxon of the lace monitor V. In the wild, adult Komodo dragons usually weigh around 70 kg lb , although captive specimens often weigh more.

The Komodo dragon has a tail as long as its body, as well as about 60 frequently replaced, serrated teeth that can measure up to 2.

Its saliva is frequently blood-tinged because its teeth are almost completely covered by gingival tissue that is naturally lacerated during feeding.

Additionally, these osteoderms become more extensive and variable in shape as the Komodo dragon ages, ossifying more extensively as the lizard grows.

These osteoderms are absent in hatchlings and juveniles, indicating that the natural armor develops as a product of age and competition between adults for protection in intraspecific combat over food and mates.

As with other varanids, Komodo dragons have only a single ear bone, the stapes , for transferring vibrations from the tympanic membrane to the cochlea.

This arrangement means they are likely restricted to sounds in the to 2, hertz range, compared to humans who hear between 20 and 20, hertz.

This was disputed when London Zoological Garden employee Joan Procter trained a captive specimen to come out to feed at the sound of her voice, even when she could not be seen.

The Komodo dragon can see objects as far away as m ft , but because its retinas only contain cones , it is thought to have poor night vision.

It can distinguish colours, but has poor visual discrimination of stationary objects. As with many other reptiles, the Komodo dragon primarily relies on its tongue to detect, taste , and smell stimuli , with the vomeronasal sense using the Jacobson's organ , rather than using the nostrils.

The scales around the ears, lips, chin, and soles of the feet may have three or more sensory plaques. The Komodo dragon prefers hot and dry places, and typically lives in dry, open grassland, savanna, and tropical forest at low elevations.

As an ectotherm , it is most active in the day, although it exhibits some nocturnal activity. Komodo dragons are solitary, coming together only to breed and eat.

For shelter, the Komodo dragon digs holes that can measure from 1 to 3 m 3. They serve as strategic locations from which to ambush deer.

Komodo dragons are carnivores. Although they have been considered as eating mostly carrion, [6] they will frequently ambush live prey with a stealthy approach.

When suitable prey arrives near a dragon's ambush site, it will suddenly charge at the animal at high speeds and go for the underside or the throat.

They have been recorded as killing wild pigs within seconds, [39] and observations of Komodo dragons tracking prey for long distances are likely misinterpreted cases of prey escaping an attack before succumbing to infection.

Komodo dragons eat by tearing large chunks of flesh and swallowing them whole while holding the carcass down with their forelegs. For smaller prey up to the size of a goat, their loosely articulated jaws, flexible skulls, and expandable stomachs allow them to swallow prey whole.

The undigested vegetable contents of a prey animal's stomach and intestines are typically avoided. A Komodo dragon may attempt to speed up the process by ramming the carcass against a tree to force it down its throat, sometimes ramming so forcefully, the tree is knocked down.

Because of their slow metabolism, large dragons can survive on as few as 12 meals a year. After regurgitating the gastric pellet, it rubs its face in the dirt or on bushes to get rid of the mucus, suggesting it does not relish the scent of its own excretions.

The largest animals eat first, while the smaller ones follow a hierarchy. The largest male asserts his dominance and the smaller males show their submission by use of body language and rumbling hisses.

Dragons of equal size may resort to "wrestling". Losers usually retreat, though they have been known to be killed and eaten by victors.

Sometimes they consume human corpses, digging up bodies from shallow graves. The Komodo dragon drinks by sucking water into its mouth via buccal pumping a process also used for respiration , lifting its head, and letting the water run down its throat.

Although previous studies proposed that Komodo dragon saliva contains a variety of highly septic bacteria that would help to bring down prey, [42] [46] research in suggested that the bacteria in the mouths of Komodo dragons are ordinary and similar to those found in other carnivores.

They actually have surprisingly good mouth hygiene. As Bryan Fry put it: "After they are done feeding, they will spend 10 to 15 minutes lip-licking and rubbing their head in the leaves to clean their mouth Unlike people have been led to believe, they do not have chunks of rotting flesh from their meals on their teeth, cultivating bacteria.

The observation of prey dying of sepsis would then be explained by the natural instinct of water buffalos , who are not native to the islands where the Komodo dragon lives, to run into water after escaping an attack.

The warm, faeces-filled water would then cause the infections. Researchers have isolated a powerful antibacterial peptide from the blood plasma of Komodo dragons, VK Based on their analysis of this peptide, they have synthesized a short peptide dubbed DRGN-1 and tested it against multidrug-resistant MDR pathogens.

Preliminary results of these tests show that DRGN-1 is effective in killing drug-resistant bacterial strains and even some fungi.

It has the added observed benefit of significantly promoting wound healing in both uninfected and mixed biofilm infected wounds. In late , researchers at the University of Melbourne speculated the perentie Varanus giganteus , other species of monitors, and agamids may be somewhat venomous.

The team believes the immediate effects of bites from these lizards were caused by mild envenomation. Bites on human digits by a lace monitor V.

In , the same researchers published further evidence demonstrating Komodo dragons possess a venomous bite. MRI scans of a preserved skull showed the presence of two glands in the lower jaw.

The researchers extracted one of these glands from the head of a terminally ill dragon in the Singapore Zoological Gardens , and found it secreted several different toxic proteins.

The known functions of these proteins include inhibition of blood clotting, lowering of blood pressure, muscle paralysis, and the induction of hypothermia, leading to shock and loss of consciousness in envenomated prey.

Other scientists have stated that this allegation of venom glands "has had the effect of underestimating the variety of complex roles played by oral secretions in the biology of reptiles, produced a very narrow view of oral secretions and resulted in misinterpretation of reptilian evolution".

According to these scientists "reptilian oral secretions contribute to many biological roles other than to quickly dispatch prey".

These researchers concluded that, "Calling all in this clade venomous implies an overall potential danger that does not exist, misleads in the assessment of medical risks, and confuses the biological assessment of squamate biochemical systems".

Mating occurs between May and August, with the eggs laid in September. These males may vomit or defecate when preparing for the fight.

Therefore, the male must fully restrain the female during coitus to avoid being hurt. Other courtship displays include males rubbing their chins on the female, hard scratches to the back, and licking.

After cutting themselves out, the hatchlings may lie in their eggshells for hours before starting to dig out of the nest. They are born quite defenseless and are vulnerable to predation.

A Komodo dragon at London Zoo named Sungai laid a clutch of eggs in late after being separated from male company for more than two years.

Scientists initially assumed she had been able to store sperm from her earlier encounter with a male, an adaptation known as superfecundation.

After Flora's eggs' condition had been discovered, testing showed Sungai's eggs were also produced without outside fertilization. The zoo has two adult female Komodo dragons, one of which laid about 17 eggs on 19—20 May Only two eggs were incubated and hatched due to space issues; the first hatched on 31 January , while the second hatched on 1 February.

Both hatchlings were males. Komodo dragons have the ZW chromosomal sex-determination system , as opposed to the mammalian XY system.

Male progeny prove Flora's unfertilised eggs were haploid n and doubled their chromosomes later to become diploid 2n by being fertilised by a polar body , or by chromosome duplication without cell division , rather than by her laying diploid eggs by one of the meiosis reduction-divisions in her ovaries failing.

When a female Komodo dragon with ZW sex chromosomes reproduces in this manner, she provides her progeny with only one chromosome from each of her pairs of chromosomes, including only one of her two sex chromosomes.

This single set of chromosomes is duplicated in the egg, which develops parthenogenetically. Eggs receiving a Z chromosome become ZZ male ; those receiving a W chromosome become WW and fail to develop, [64] [65] meaning that only males are produced by parthenogenesis in this species.

It has been hypothesised that this reproductive adaptation allows a single female to enter an isolated ecological niche such as an island and by parthenogenesis produce male offspring, thereby establishing a sexually reproducing population via reproduction with her offspring that can result in both male and female young.

Attacks on humans are rare, but Komodo dragons have been responsible for several human fatalities, in both the wild and in captivity.

According to data from Komodo National Park spanning a year period between and , there were 24 reported attacks on humans, five of them fatal.

Most of the victims were local villagers living around the national park. The Komodo dragon is classified by the IUCN as a vulnerable species and is listed on the IUCN Red List.

Komodo National Park was founded in to protect Komodo dragon populations on islands including Komodo, Rinca, and Padar.

Komodo dragons generally avoid encounters with humans. Juveniles are very shy and will flee quickly into a hideout if a human comes closer than about metres ft.

Older animals will also retreat from humans from a shorter distance away. If cornered, they may react aggressively by gaping their mouth, hissing, and swinging their tail.

If they are disturbed further, they may attack and bite. Although there are anecdotes of unprovoked Komodo dragons attacking or preying on humans, most of these reports are either not reputable or have subsequently been interpreted as defensive bites.

Only a very few cases are truly the result of unprovoked attacks by abnormal individuals which lost their fear of humans.

Volcanic activity, earthquakes, loss of habitat, fire, [28] [19] tourism, loss of prey due to poaching , and illegal poaching of the dragons themselves have all contributed to the vulnerable status of the Komodo dragon.

Under Appendix I of CITES the Convention on International Trade in Endangered Species , commercial trade of Komodo dragon skins or specimens is illegal.

In , the total population of Komodo dragons in the wild was assessed as 3, individuals, declining to 3, in and 3, in Populations remained relatively stable on the bigger islands Komodo and Rinca , but decreased on smaller islands such as Nusa Kode and Gili Motang, likely due to diminishing prey availability.

Komodo dragons have long been sought-after zoo attractions, where their size and reputation make them popular exhibits.

They are, however, rare in zoos because they are susceptible to infection and parasitic disease if captured from the wild, and do not readily reproduce in captivity. Young Komodo dragons are arboreal and live in forested regions until they are eight months old. Ik ga in september verhuizen naar Nederland, in Roosendaal.
