The Rare Indonesian Animal History
|Komodo dragon |
Komodo dragon distribution
The Komodo dragon (Varanus komodoensis) is a species of lizard that lives in the Indonesian islands of Komodo, Rincah, Flores, Gili Motang, and Gili Dasami. It is the largest living kind of lizard. They grow to an average length of 2–3 meters (approximately 6.5–10 ft) and weigh around 70kg (154 pounds). Komodo dragon bites can be very dangerous, and they sometimes attack people.
Western scientists first saw Komodo dragons in 1910. They are very popular animals in zoos because they are very big and look scary. The lizards are in some danger. There are very few Komodo dragons still alive on their home islands. Indonesian law does not allow hunting these lizards. Komodo National Park was made to help protect Komodo dragons.
The Komodo dragon has other names. It can also be called the Komodo Monitor or the Komodo Island Monitor by some scientists, but this is not very common. The people who live in Komodo Island call them ora, buaja durat (land crocodile) or biawak raksasa (giant monitor).
The Komodo dragon is cold-blooded. It has a tail as long as its body. It has about 60 sharp teeth that can grow up to 2.5 centimeters (1 inch) long. It also has a long, yellow, forked tongue. Its saliva is red because its gums almost completely cover its teeth. When they eat, their teeth cut their gums and make them bleed. This creates a good environment for the dangerous bacteria that live in its mouth.
People used to think they were very big because there are no other large, meat-eating animals on the islands where they live. Therefore they did not have to compete with other similar animals for the same food and places to live. People also thought they were big because of their low metabolic rate.
However, recent researchers have suggested a new idea. They say the Komodo is the last one of a larger group of lizards called varanids. These different types of lizards once lived across Indonesia and Australia but most of them died out after contact with modern humans. These varanids were all the best hunters in their habitats. These lizards dominate the areas where they live because they are so big.
The Komodo dragon’s earholes are easy to see, but Komodo dragons are not very good at hearing. It is able to see as far away as 300 meters (985 feet), but it is thought to have poor night vision. The Komodo dragon is able to see in color, but has trouble seeing objects that do not move.
The Komodo dragon uses its tongue to taste and smell like many other reptiles. They have a special part of the body called the Jacobson’s organ for smelling. With the help of a good wind, they can smell dead animals from 4–9.5 kilometres (2.5–6 mi) away. The Komodo dragon’s nostrils are not very useful for smelling, because it does not have a diaphragm. It only has a few taste buds in the back of its throat. Its scales have special connections to nerves that give the lizard a sense of touch. The scales around its ears, lips, chin, and bottoms of the feet may have three or more of these connections.
Komodo dragons have dangerous bacteria in their saliva. Scientists have identified 57 of them. One of the most dangerous bacteria in Komodo dragon saliva appears to be a kind of Pasteurella multocida. These bacteria cause disease in the blood of their victim. If a bite does not kill an animal and it escapes, it will usually die within a week from infection. The Komodo dragon seems to never get sick from its own bacteria. So, researchers have been looking for the lizard’s antibacterial. This maybe used as medicine for humans.
Mating begins between May and August, and the eggs are laid in September. Dragons leave about twenty eggs in empty nests left by birds called megapodes. The eggs develop for seven to eight months. The eggs open and the baby lizards come out in April, when there are many insects to eat. Young Komodo dragons live in trees, where they are safe from adult Komodo dragons and other animals that might eat them. They take around three to five years to mature and may live as long as fifty years. Female Komodo dragons can have babies in a special way without a male lizard.
The Komodo dragon likes hot and dry places and lives in dry open grassland, savanna, and tropical forest on lower land. It is most active in the day because it is cold-blooded, although it is sometimes active at night. Komodo dragons live alone. They come together only to breed and eat. They can run up to 20 kilometers per hour (12.4 mph), dive up to 4.5 metres (15 ft) at top speed for short periods of time. When they are young, they climb trees with their strong claws. As the Komodo dragon grows bigger, its claws are used mostly as weapons, because it is too big to climb trees well.
The Komodo dragon digs holes for protection with its powerful legs and claws. These holes can be from 1–3 metres (3–10 ft) wide. Because it is very big and sleeps in holes, it is able to keep itself warm through the night. The Komodo dragon usually hunts in the afternoon, but stays in the shade during the hottest part of the day. Komodo dragons have special resting places on ridges that catch cool sea breezes.
Komodo dragons are carnivores, which means that they eat meat. Although they eat mostly dead animals they will also catch live animals as prey. When prey goes by a Komodo dragon, it will suddenly charge at the animal and bite or claw the belly or the throat. To catch animals that are up high and out of reach, the Komodo dragon may stand on its back legs and use its tail as a support.
Komodo dragons do not chew their food. They eat by biting and pulling off large chunks of flesh and swallowing them whole. They can swallow smaller prey, up to the size of a goat, whole. This is because they have flexible jaws and skulls, and their stomachs can expand. Komodo dragons make much saliva to help the food move easily, but swallowing still takes a long time (15–20 minutes to swallow a goat). Komodo dragons may try to swallow faster by running and pushing the dead animal in its mouth very hard against a tree. Sometimes a lizard hits the tree so hard that it gets knocked out. Dragons breath using a small tube under the tongue that connects to the lungs. This allows it to continue breathing even while swallowing large things. Komodo dragons can eat up to 80 percent of its body weight in one meal. After swallowing its food, it drags itself to a sunny place to speed up digestion so the food does not rot and poison the dragon. Large dragons can survive on as little as 12 meals a year. After digestion, the Komodo dragon vomits the horns, hair, and teeth of the animal it ate. This vomit is covered in a smelly mucus. After vomiting, it rubs its face in the dirt or on bushes to get rid of the mucus. This suggests that komodo dragons dislike the smell, just like humans do.
The largest animals usually eat first, while the smaller ones eat later. Dragons of equal size may wrestle each other. Losers usually run away, although sometimes they are chased and eaten by the winners.
The Komodo dragon’s diet includes invertebrates, other reptiles (including smaller Komodo dragons), birds, bird eggs, small mammals, monkeys, wild boars, goats, deer, horses, and water buffalo. Young Komodo dragons will eat insects, eggs, geckoes, and small mammals. Komodo dragons may eat people and, they can even dig up bodies from their graves to eat them. Therefore, people on Komodo Island moved their graves from sandy to clay ground and piled rocks on top to stop the lizards from digging up dead bodies.
Because the Komodo dragon does not have a diaphragm, it cannot suck water when drinking. It cannot lap water with its tongue either. Instead, it drinks by taking a mouthful of water, lifting its head, and letting the water run down its throat.
Recent fossils from Queensland suggests that the Komodo dragon evolved in Australia before spreading to Indonesia. Its body size remained stable on Flores, ever since the islands were isolated by rising sea levels, about 900,000 years ago. The sea level dropped very low during the last ice age and uncovered wide areas of continental shelf. The Komodo dragon spread into these areas. They became isolated on the islands where they live today when sea levels rose again. They moved into what is now the Indonesian island group. They spread as far east as the island of Timor.
Komodo dragons and people
Komodo dragons have been popular in zoos for a long time. However, there are few of them in zoos because they may become sick and do not have babies easily. As of May 2009, there are 13 European, 2 African, 35 North American, 1 Singaporean, and 2 Australian institutions that keep Komodo dragons.
A Komodo dragon was shown in a zoo for the first time in 1934 at the Smithsonian National Zoological Park. But, it lived for only two years. People continued to try to keep Komodo dragons in zoos, but the lives of these creatures was very short. The average life of a dragon in a zoo was five years in the National Zoological Park. Walter Auffenberg studied the dragons in zoos and eventually helped zoos to keep dragons more successfully
Many dragons in zoos may become tamer than wild lizards within a short period of time in a zoo. Many zoo keepers have brought the animals out of their cages to meet visitors without any problems. Dragons can also recognize individual humans. However, even dragons that seem tame may surprise people and become aggressive. This can often happen when a stranger enters the animal’s home.
Komodo dragons at Toronto Zoo. Komodo dragons in captivity often grow fat, especially in their tails, due to regular feeding.
Research with captive Komodo dragons has shown that they play. One dragon would push a shovel left and seemed attracted to the sound of it moving across rocks. A young female dragon at the National Zoo in Washington, D.C. would grab and shake things like statues, drink cans, plastic rings, and blankets. She would also put her head in boxes, shoes, and other objects. She did not make a mistake and think these objects were food; she would only swallow them if they were covered in rat blood.
Danger to humans
Komodo dragons do not attack human very often. However, they do sometimes hurt or kill people.
In June 2001, a Komodo dragon seriously hurt Phil Bronstein—executive editor of the San Francisco Chronicle. Bronstein had entered the dragon’s cage at the Los Angeles Zoo after being invited in by its keeper. The zoo keeper had told him to take off his white shoes, which could have excited the Komodo dragon. Bronstein was bitten on his bare foot. Although he escaped, he needed surgery to repair his foot.
On June 4, 2007, a Komodo dragon attacked an eight-year-old boy on Komodo Island. The boy later died because he lost too much blood. This was the first time that people know a dragon had killed a human in 33 years. Local people blamed the attack on environmentalists. People from outside the island had stopped local people from killing goats and leaving them for the dragons. The Komodo dragons no longer found the food they needed, so they came into places where humans lived in search of food. Many natives of Komodo Island believe that Komodo dragons are actually the reincarnation of relatives and should be treated with respect.
On March 24, 2009, two Komodo dragons attacked and killed fisherman Muhamad Anwar on Komodo Island. They attacked Anwar after he fell out of a sugar-apple tree. He was bleeding badly from bites on his hands, body, legs, and neck. He was taken to a clinic on the nearby island of Flores, but doctors said he was dead when he arrived.
