<b>The Tiger's Secret Weapon: Its roar can paralyze an animal or a person. </b> Anyone who hears a loud tiger roar will break out in a cold sweat. But scientists say that the voice of a predator can not only frighten, but also paralyze. One moment, one sound, and you are a helpless victim, ready for consumption. However, all this smacks of mythology. Did the tiger always have a superpower that we didn't know about? First, let's look at how a tiger hunts. Here he, like a compressed spring, fell to the ground. Ahead, next to a watering hole, several wild boars roam. They are unaware of the predatory cat. Careful steps downwind bring the hunter closer and closer to the target. The moment of truth: right now the tiger must use his superweapon, here’s one more step and... The predator makes several powerful jerks towards the wild boars, jumps, flies several meters, a moment later only the frightened squeal of the caught victim is heard. But there was no trace of any roar... Why? The tiger is an ambush predator. Until the very last second, it is important for him to maintain incognito status: hide in the tall grass, mask his smell and not give himself away by any sound. He will not growl at his prey; after all, it will run into the thicket with its tail raised, losing some of its weight as it goes. Does this mean that paralysis caused by a roar is bullshit? Yes and no. Yes, because tigers are focused and keep their mouths shut when hunting. Otherwise they will be left without dinner. Hunting tactics simply do not tolerate loud statements, but... let's ask ourselves another question. Why do tigers even roar? Big cats are introverts to the core. The territory of one individual reaches from 10 to 100 km². The tabby has not yet invented the telephone, so the only way to communicate with each other is a loud roar that can be heard for several kilometers. And this is the secret. Biologists studying tiger communication have noticed that big cats communicate with each other at low frequencies - at the infrasound level. Such waves travel much further than usual, penetrating into buildings, through dense forests, mountains and... our body. The human ear cannot hear infrasound. Most mammals, including humans, recognize frequencies between 20 and 20,000 hertz. Tigers speak at a frequency of 18 hertz. However, low-frequency vibrations cause internal organs to resonate and vibrate. Our body literally trembles from the tiger's roar. Of course, the power of a big cat’s ligaments is not enough to break a heart. But low frequencies cause anxiety and fear on a physiological level. And then the classic scheme follows: fight or flight, or freeze. And if your response to intense fear is to imitate a deer frozen in headlights, then a tiger's roar can definitely be paralyzing. But no magic, mysticism or superpowers. Only the power of physics and biology! Author: Egor Churakov Editor: Elizaveta Isaeva <b>🏀 Hit the hoop and get an NFT gift — </b><b>https://t.
