The Komodo dragon swallowed a deer in 29 seconds, the world's largest lizard, weighing 166 kilograms, eating 80% of the weight of food in one meal, eating 62 pounds of wild boar in 20 minutes, and their weapons are deadly bacteria and venom, because the metabolism is very slow, and they can survive by eating one meal a month.
Komodo dragons are mainly distributed on the Indonesian islands of Komodo, Rinca, Flores and Mordo, and also have a small presence in the Gambia, South Africa, this monitor lizard is already an endangered species, there are currently about 5700 in the world. When it was first discovered, it was thought to be some kind of small dinosaur, so there was another name called Komodo Dragon.
The Komodo monitor lizard is the largest lizard on Earth, with an average body length of 2-3 meters and an average weight of 68-91 kg. The world's largest one in the United States, in 1928 an American zoologist obtained a specimen of a Komodo dragon, 3.1 meters long and weighing 166 kilograms, which is also the largest one on Earth.
This amazing animal has lived on Earth for more than 40 million years, and although not dinosaurs, they are a large carnivorous reptile with a fierce temperament, love to fight, and even eat weaker counterparts when food is scarce. Their food is very mixed, as long as they can beat it, such as wild boar, deer, monkeys, and bushhoppers. Birds, goats and buffalo, etc.
They prefer hot and dry places and are active in the daytime, after all, there are no predators on the island and they are protected by people. Although these monitor lizards are usually lonely, they gather together when they eat and reproduce. They can hear sounds in the range of 400-2000 hertz and can also see prey 300 meters away. Their sense of smell is the most powerful, but the smell is not on the nose, but on the tongue.
Komodo dragons had forked tongues with the plow nose organs of Jacobson's organs, and with the help of the wind, they could smell carrion up to 9.5 kilometers away. You can run quickly in a short sprint of 20 km / h to catch prey, with more than 60 sharp teeth in the mouth, and the length of 2.5 cm is the shape of a curved hook, which is conducive to tearing the skin of the prey.
It was previously thought that Komodo dragons were often carrion, and their saliva contained more than 70 species of bacteria, and a bite of their prey would cause them to infect and die. In fact, the bacteria in the saliva of Komodo dragons are not the main source of toxicity. In their jaws there are 2 venom glands, which connect the teeth to inject venom. At the moment of biting the prey, it begins to inject venom through the tiny holes in the teeth, so it is a blood-type toxin.
Komodo dragons are not low in IQ at all, they can plan the route of attack, and can keep an eye on their prey for up to ten days. After all, there are many prey larger than them on the island, such as some bison that can trample to death and overturn monitor lizards when they go berserk. In order to be able to hunt bison, they will lurk and suddenly take a bite on the cow's leg, but this is only the beginning of the hunt.
Although this mouth injected some venom, but the bison is very large, the liver is also very capable of breaking down the poison, Komodo dragons can only slowly wait for the opportunity, once the bison runs away, it will catch the tracks of prey according to the smell. You must find your own food after the bison has been poisoned to death, before other opponents find the bison.
This is a long process, large bison generally take about 7-15 days to be attacked by toxicity, at this time the monitor lizard, although hungry, but turn a blind eye to other foods such as wild boar, monkeys, etc. After all, cattle are big, and they can eat a meal and not eat for a month. When the dual effects of venom and bacteria in the bison fall, the monitor lizard can eat.
It is precisely because of this tough personality that this large, not very fast prey survives. If it is a small prey such as an antelope, as long as it is bitten, the venom will make the antelope's blood unable to coagulate, resulting in excessive blood loss, muscle paralysis, loss of consciousness, shock and other symptoms, and soon be able to eat. The small ones swallow directly as in Figure 1, and the large ones will decompose first and then eat.
If a group of monitor lizards catch a prey, their feeding is regular, usually the largest and strongest eat first, and will use their strong tails to whip the same kind of food to grab the food, when it is full of other kinds can come to eat. Their stomachs are like an elastic rubber skin bag, which can swallow a whole small prey, such as a monitor lizard 100 kilograms, a meal can eat an 80 kilogram prey, and the powerful stomach acid will slowly break down the bones.
Komodo monitor lizards are oviparous animals, generally laying eggs in September, a litter can lay 20 eggs, female lizards will bury their eggs in the sand, relying on the temperature of the sun to incubate eggs, life expectancy can generally reach about 50 years. In 2006, a female Komodo dragon kept alone in the United Kingdom actually had the strange phenomenon of parthenogenesis, that is, a single female lizard can have many offspring. #Punch Card Challenge Bureau## Topic Big Inventor ##所见所得, very scientific #
