Komodo Dragons (3)

And bacteria can 

In late 2005, researchers from the University of Melbourne, Australia, concluded that Perentie lizard (Varanus giganteus) and other lizards, monitor lizards, and lizards from the tribe Agamidae, probably have some sort of can. As long as it is known that injuries from the bite of these animals are very prone to infection because of bacteria that live in the mouth of these lizards, but the researchers suggest that the direct effect that appears in the bite wounds were caused by the influx could force medium. These researchers have observed the wounds in the hands of humans from the bite lizard Varanus varius, V. scalaris and dragons, and all showed a similar reaction: rapid swelling within minutes, local disturbances in blood clotting, pain that gripped up to the elbow, with some symptoms that last up to several hours later. In addition to containing can, komodo dragons saliva also has a variety of deadly bacteria in it, for more than 28 Gram-negative and 29 Gram-positive have been isolated from this saliva. These bacteria cause septicemia in their victims, if not directly kill the dragons bite their prey and prey that can escape, usually the unlucky prey will die within one week due to infection. The most deadly bacteria in Komodo dragon saliva bacterium Pasteurella multocida presumably is highly lethal; known through experiments with laboratory mice. [28] Because the Komodo dragon appears immune to its own microbes, much research done to look for the antibacterial molecule in the hope that can be used for human treatment.
Reproduction
In this picture, claw dragons can be seen clearly. 

Note the large nails. His nails are used to fight and eat. The mating season occurs between May and August, and eggs laid in September. During this period, male dragons battle to defend the females and territory by wrestling with another male standing on his hind legs. Komodo the loser will fall to the ground and locked. Both male Komodo dragon that can vomit or defecate when preparing for battle. The winner will fight long tongue flicked on the female body to see the female acceptance.Antagonistic female dragons and fight with their teeth and claws in pairs during the initial phase. Furthermore, males have to fully control the female during intercourse so as not to hurt. Other behaviors that are shown during this process is the male rubbing their chins on the female, hard on the back scratching and licking. Copulation occurs when males enter one hemipenisnya to the female cloaca. Komodo can be monogamus and form pairs, a rare trait for a lizard.
Females will lay their eggs on the ground hole, scraping the cliff of the hill or mound of charred birds nest-orange legs that have been abandoned. Komodo would prefer to keep their eggs in nests that had been abandoned. An average dragons nest contained 20 eggs that will hatch after 7-8 months. Females lay on the eggs to incubate and protect them until they hatch around April, at the end of the rainy season when there are so many insects.
Business incubation process is exhausting for children dragons, which came out of the shell egg after egg tore with teeth that will be dated after the heavy work is completed. After successfully tore eggshells, the baby dragons to lay their eggs in the shell for a few hours before starting to dig out their nests. When hatched, the babies are not just how helpless and can be eaten by predators.
Young Komodo dragons spend their first years on the tree, where they are relatively safe from predators, including adult dragons are cannibals, which is about 10% of food is a young lizard-iguana successfully hunted. Komodo takes three to five years to mature, and can live more than 50 years.
In addition to the normal reproductive process, there are several examples of cases of female dragons to produce children without the presence of males (parthenogenesis), a phenomenon also known to appear in several other reptile species such as Cnemidophorus.

Parthenogenesis 
Sungai, a Komodo dragon at London Zoo, has been laying eggs in early 2006 after the split of males for more than two years. Scientists initially thought that these dragons can store sperm for some time the result of mating with a male Komodo dragon at the previous time, an adaptation known as superfekundasi.
On December 20, 2006, it was reported that Flora, the Komodo dragon living in Chester Zoo, UK is the second dragons are known to produce eggs without fertilization (conception of marriage): he took out 11 eggs, and 7 of them managed to hatch. Researchers from the University of Liverpool in northern England perform genetic tests on three eggs that failed to hatch after moved into the incubator, and proved that Flora did not have physical contact with male dragons. After this surprising finding, and testing conducted on the eggs of the River and found that the eggs and even then produced without fertilization from the outside. Komodo has a ZW chromosomal sex-determination system, rather than the XY sex determination system. Flora of androgynous male offspring, indicating the occurrence of several things. Flora is that the eggs are not fertilized are haploid at first and then doubling the chromosomes themselves become diploid, and that he did not produce diploid eggs, as can occur if one-reduction division process of meiosis in ovaries fail.When a female Komodo dragon (a ZW sex chromosomes) to produce the child in this way, he passed only one of the pairs of chromosomes that dipunyainya, including one of two sex chromosomes. A single set of chromosomes is then duplicated in the egg, which is growing at a partenogenetika. Eggs that received Z chromosome would be a ZZ (male), and who receive W chromosome will become WW and fail to develop. Suspected that this kind of reproductive adaptation allows an animal to enter a female an isolated ecological niche (such as islands) and then by parthenogenesis produce male offspring. Through marriage with his son on the next time these animals to form a population that reproduce sexually, being able to produce male and female offspring. Although these adaptations are beneficial, the zoo needs to be alert because parthenogenesis may be able to reduce genetic diversity.
On January 31, 2008, Sedgwick County Zoo in Wichita, Kansas became the zoo who first documented parthenogenesis in Komodo dragons in America. The zoo has two adult female Komodo dragon, which is one of them produced 17 eggs in 19 to 20 May 2007. Only two eggs are incubated and hatched because the issue of space availability; the first hatched on January 31, 2008, followed by the second on 1 February. Both children were androgynous male Komodo dragon.
