A dedication to the bored and jobless.

I'm so bored like hell. I'm currently cahtting with my baby. It goes a little something like this:


Ass. just sent you a nudge.

You have just sent a nudge.

Ass. says (6:07 PM):
behh
Ass. says (6:07 PM):
:)
Nani says (6:07 PM):
apakan nudge nudge ani?
Ass. says (6:07 PM):
i Love you man.
Ass. says (6:07 PM):
haha
Nani says (6:07 PM):
i love you too wah dude.



hahah. Well, that's my baby. I love my baby to teenyweeny bits.

Anyway, I had an all-boring day today. Been missing my baby. Ahh.. And I miss my baby girls. Nabilah Rosli, Piyawan Takamchai and Nabilah Hazirah Karim. I know I know. I've alredy met them last night. Piya, Zye and I watched The Coffin. It was awesome! It could've been better if nabs was with us as well. But oh well, at least we had fun. It's not Nabs's fault she had to go home early.

My mind is so messed up right now. For I don't know what reason. I mean, exam's over. What more should I be thinking about? Hmm.. Maybe it's because I miss my baby too much.

I did this little discovery. I'm really into all sorts of reptiles. It all started when I disected a lizard when I was 5 years old. I'm not a criminal or a weirdo, okay? I was just amazed when I saw its tail was still moving eventhough it was disconnected to the other remainings of its tail. So, it made me thought. Why not cut its body to half. And I did. I remembered I saw somethinhg white-ish looking in it. I think it was an egg. Oh well. Anyway, I have this huge interest in snakes, lizards, dinosaurs etc. My favourite reptile is the Komodo Dragon. So far, I can't get enough of that thing. I know its deadly and everything. But I'd like to have the opportunity to study that deadly creature someday. The Komodo dragon (Varanus komodoensis) is a species of lizard that inhabits the islands of Komodo, Rincaa, Floress, Gili Motang , and Gili Dasami, in central Indonesia. A member of the monitor lizard family (Varanidae), it is the largest living species of lizard, growing to an average length of 2 to 3 metres (6.6 to 9.8 ft) and weighing around 70 kilograms (150 lb). Their unusual size is attributed to island gigantism, since there are no other carnivorous animals to fill the niche on the islands where they live, and also to the Komodo dragon's low metabolic rate. As a result of their size, these lizards are apex predators, dominating the ecosystems in which they live. Although Komodo dragons eat mostly carrion, they will also hunt and ambush prey including invertebrates, birds, and mammals.

It's quite a rare species. You don't find it very often. The Komodo dragon started with the Varanus genus, which originated in Asia about 40 million years ago and migrated to Australia. Around 15 million years ago, a collision between Australia and Southeast Asia allowed the varanids to move into what is now the Indonesian archipelago. The Komodo dragon is believed to have differentiated from its Australian ancestors 4 million years ago, extending their range to as far east as the island of Timor. The ice age and its dramatic sea level changes brought the islands that the Komodo dragons inhabited into their present locations, isolating them in their present range.

The Komodo dragon does not have a particularly acute sense of hearing, despite its visible earholes, and is only able to hear sounds between 400 and 2000 hertz. It is able to see as far away as 300 metres which is about 980ft. , but because its retinas only contain cones, it is thought to have poor night vision. The Komodo dragon is able to see in color, but has poor visual discrimination of stationary objects. The Komodo dragon uses its tongue to detect taste and smell stimuli, as with many other reptiles, with the vomeronasal sense using a Jacobson's organ, a sense that aids navigation in the dark. With the help of a favorable wind and its habit of swinging its head from side to side as it walks, Komodo dragons may be able to detect carrion from 4–9.5 kilometres (2.5–6 mi) away. The dragon's nostrils are not of great use for smelling, as the animal does not have a diaphragm. It only has a few taste buds in the back of its throat. Its scales, some of which are reinforced with bone, have sensory plaques connected to nerves that facilitate its sense of touch. The scales around the ears, lips, chin, and soles of the feet may have three or more sensory plaques. The Komodo dragon was formerly thought to be deaf when a study reported no agitation in wild Komodo dragons in response to whispers, raised voices, or shouts.

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 largely solitary, coming together only to breed and eat. They are capable of running rapidly in brief sprints up to 20 kilometres per hour (12.4 mph), diving up to 4.5 metres (15 ft), and climbing trees proficiently when young through use of their strong claws. To catch prey that is out of reach, the Komodo dragon may stand on its hind legs and use its tail as a support. As the Komodo dragon matures, its claws are used primarily as weapons, as its great size makes climbing impractical.

For shelter, the Komodo dragon digs holes that can measure from 1–3 metres (3–10 ft) wide with its powerful forelimbs and claws. Because of its large size and habit of sleeping in these burrows, it is able to conserve body heat throughout the night and minimize its basking period the morning after. The Komodo dragon typically hunts in the afternoon, but stays in the shade during the hottest part of the day. These special resting places, usually located on ridges with a cool sea breeze, are marked with droppings and are cleared of vegetation. They also serve as a strategic location from which to ambush deer.

Komodo dragons are carnivores. Although they eat mostly carrion, they will also ambush live prey with a stealthy approach. When suitable prey arrives near a dragon's ambush site, it will suddenly charge at the animal and go for the underside or the throat. It is able to locate its prey using its keen sense of smell, which can locate a dead or dying animal from a range of up to 9.5 kilometers (6 miles). Komodo dragons have also been observed knocking down large pigs and deer with their strong tail.

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 skull, and expandable stomach allow it to swallow its prey whole. The vegetable contents of the stomach and intestines are typically avoided. Copious amounts of red saliva that the Komodo dragons produce helps to lubricate the food, but swallowing is still a long process (15–20 minutes to swallow a goat). Komodo dragons may attempt to speed up the process by ramming the carcass against a tree to force it down its throat, sometimes ramming so forcefully that the tree is knocked down. To prevent itself from suffocating while swallowing, it breathes using a small tube under the tongue that connects to the lungs. After eating up to 80 percent of its body weight in one meal, it drags itself to a sunny location to speed digestion, as the food could rot and poison the dragon if left undigested for too long. Because of their slow metabolism, large dragons can survive on as little as 12 meals a year. After digestion, the Komodo dragon regurgitates a mass of horns, hair, and teeth known as the gastric pellet, which is covered in malodorous mucus. After regurgitating the gastric pellet, it rubs its face in the dirt or on bushes to get rid of the mucus, suggesting that it, like humans, does not relish the scent of its own excretions.

The largest animals generally 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 have been known to be killed and eaten by victors.

Komodo dragons also possess virulent bacteria in their saliva, of which more than 28 Gram-negative and 29 Gram-positive strains have been isolated. These bacteria cause septicemia in their victim; if an initial bite does not kill the prey animal and it escapes, it will commonly succumb within a week to the resulting infection. The most harmful bacterium in Komodo dragon saliva appears to be a deadly strain of Pasteurella multocida, from studies performed with lab mice. There is no specific antidote to the bite of a Komodo dragon, but it can usually be treated by cleansing the wounded area and giving the patient large doses of antibiotics. If not treated promptly, gangrene can quickly develop around the bite, which may require amputation of the affected area. Because the Komodo dragon appears immune to its own microbes, much research has been done searching for the antibacterial molecule(s) in the hopes of human medicinal use.

Oh well, that's all the facts I can collect about this deadly species.
