It is not for nothing that cheetahs have characteristics that make them completely different from other felines. The cheetah has a structure in which everything in its body invests everything in running fast, and boasts the highest speed in mammals, around 110 km per hour. This is a trait specialized for hunting fast hoofed mammals such as gazelles. The small, slender head reduces air ํผ์๊ฒ์2 1ํ 2ํ ๋ค์ ๋ณด๊ธฐ 230428โ
resistance, the chest is flat, and the heart and lungs are large. Its legs are long and its body length is long, so it has a wide stride and its flexible spine acts as a spring, allowing it to run at full speed while exploding the kinetic energy of the whole body. The cervical vertebrae are also very flexible, so despite the violent jumps, the head is fixed without moving up and down as if floating in the air, so it can aim precisely at the target.ํผ์๊ฒ์2 1ํ 2ํ ๋ค์ ๋ณด๊ธฐ 230428โ
Meanwhile, the cheetah's non-retractable claws act like sprinters' spikes when running. The claws spur the ground and help the cheetah's body move further forward. The cheetah leaps about 7m per step and can do this up to 4 times per second, which is equivalent to running 100m in 3 seconds. An 11-year-old female cheetah named 'Sera' from the Cincinnati Zoo in the United States ran the 100m in 6.13 seconds from a standstill in 2009 and 5.95 ํผ์๊ฒ์2 1ํ 2ํ ๋ค์ ๋ณด๊ธฐ 230428โ
seconds in 2012. At the time of the 2012 record measurement, the speed passing the 100m point was 61 mph.# Generally, it takes 3 seconds for a cheetah to reach 100 km/h or 62 mph, which is a similar unit from a standstill. The supercar Lamborghini Aventador is 2.9 seconds. Even motorcycles often go over 20 seconds for 125cc models, and at least 600cc go down to 2 seconds.[9]ํผ์๊ฒ์2 1ํ 2ํ ๋ค์ ๋ณด๊ธฐ 230428โ
However, it is not possible to maintain this speed for a long time, but after running 200 to 300 m, the speed drops significantly. Cats and wild beasts have very low sprinting endurance, but in the case of cheetahs, it peaks at 300 meters, running for about 10 seconds. Overheating because the heart beats so rapidly that it pumps blood. Beyond 500m, you are completely at your limit, and you must rest after sprinting. If it is out of limits, organs will be ํผ์๊ฒ์2 1ํ 2ํ ๋ค์ ๋ณด๊ธฐ 230428โ
damaged due to the state of blood flow or body heat.[10] It is said that if you continue to run in this state, you may die. Therefore, animals that frequently encounter cheetahs spend time in the open plains, detect cheetahs from a distance and run away early, even if cheetahs chase them, the cheetahs get tired first before the distance gap is narrowed. In the end, the cheetah's ability as a food stalker has become the best among beasts of prey, and it quietly approaches the prey until it is close to the distance, then suddenly runs out and snatches the neck. An ability that is more necessaryํผ์๊ฒ์2 1ํ 2ํ ๋ค์ ๋ณด๊ธฐ 230428โ
for females who must hunt alone than males who can hunt in groups. In fact, females are better stalkers than males. It feeds mainly on antelopes such as Grant's gazelle, Thomson's gazelle, springbok, impala, and richue, and also hunts other animals such as warthogs and rabbits. Females usually hunt alone, but males usually hunt in groups of brothers or in groups. Unlike other feline beasts of prey, cheetahs hunt mainly during the day, as they are often threatened by dangerous nocturnal competitors such as lions and leopards.ํผ์๊ฒ์2 1ํ 2ํ ๋ค์ ๋ณด๊ธฐ 230428โ
Because it has a powerful weapon that other predators do not have, such as tremendous speed, the hunting success rate is somewhat high. It is about 30-40% successful, which is higher than other felines, but it is not such an easy hunt. Small antelopes, such as Thomson's gazelles, which are the cheetah's prey, divert the cheetah's concentration because they have a defensive technique of running away in all directions, changing directions and changing ํผ์๊ฒ์2 1ํ 2ํ ๋ค์ ๋ณด๊ธฐ 230428โ
positions in groups to evade pursuit. In addition, since it gets tiring after running for only a few seconds, if you don't secure the distance before attacking, you may miss the food you caught because you almost caught up but your stamina reaches the limit.ํผ์๊ฒ์2 1ํ 2ํ ๋ค์ ๋ณด๊ธฐ 230428โ
Therefore, preparation for hunting is a typical feline mammalian method of basically covering up a lack of endurance by ambush and surprise. But attacks are different. The cheetah's body is optimized for speed, so hunting is all about speed. Unlike lions and leopards, they do not attack by jumping, but by their own speed. This power is so great that even a Grant's gazelle, twice as large as a cheetah, rolls to the ground in an instant. After that, the common end of cats and mammals that kill by biting the neck. Its head is small, but its canine teeth are long and sharp, like a feline, so it strikes precisely where the artery flows.ํผ์๊ฒ์2 1ํ 2ํ ๋ค์ ๋ณด๊ธฐ 230428โ
Males living in packs usually hunt small animals, but rarely hunt larger game such as wildebeest, ostrich, and zebra. In the case of silkworms, they usually attack the herd to hunt their young, and they do not target ostriches or zebras.ํผ์๊ฒ์2 1ํ 2ํ ๋ค์ ๋ณด๊ธฐ 230428โ
Occasionally, they aim for the prey hunted by their own people, and even if there are many thieves and are stronger, the individual who has already taken the prey is psychologically superior, so when the owner of the prey attacks, the thieves shrink and retreat.ํผ์๊ฒ์2 1ํ 2ํ ๋ค์ ๋ณด๊ธฐ 230428โ
Asian cheetahs mainly hunt antelope, rabbits, and Persian fallow deer. However, like male cheetahs in Africa, male cheetahs in this region occasionally hunt prey three to four times larger than themselves. Although rare, it preys on wild donkeys, wild horses, and occasionally wild boars [13].ํผ์๊ฒ์2 1ํ 2ํ ๋ค์ ๋ณด๊ธฐ 230428โ

The Morning After: Virgin Galactic goes to space
Hey, good morning! You look fabulous.
What'd you do this week? If it didn't involve a historic trip into space then Richard Branson and Virgin Galactic have you beat. Other out-of-reach experiences include hopping behind the wheel of McLaren's 720S and taking a selfie on Mars, but we can all share the season-two trailer of Star Trek Discovery.
First human spaceflight launched from the US since 2011.Virgin Galactic's SpaceShipTwo reaches space for the first time
SpaceShipTwo has reached space after months of testing, flying to an altitude of 271,268 feet before returning to Earth. The stay was brief (SST fired its rocket for all of a minute), but it was enough to both verify the spacecraft as well as conduct four NASA-backed scientific experiments that studied the effects of microgravity and devices that could handle life support and counteract vibration.
Beauty and brains.McLaren's 720S is a glorious nerd-built supercar
At $288,000, the McLaren 720S is out of the reach of pretty much everyone. For those lucky enough to have a chance to get behind the wheel, it's an absolute blast even when it's constrained by the realities of city driving. That's thanks to an active suspension system developed at Cambridge University -- and whatever those nerds were doing, worked.
A Valve-Epic rivalry isn't a matter of life or death for either company.The Epic Games Store is the best thing that could happen to Steam
Before it could properly innovate, Steam needed competition. And now, with the launch of the Epic Games Store, it has exactly that.
Someone show this to Stephen Curry.NASA's InSight lander proves it's on Mars with a selfie
Next time you can't find the perfect angle for your selfie, just thank the universe you're not NASA's InSight lander. The spacecraft had to take 11 images with a camera attached to its robotic arm and then stitch them together to create its first self portrait.
