Washington: Have you ever heard the hiss of a snake? The snake hisses. Now stop the video once and try to make a noise like a snake. You will notice that this sound comes from the air coming out between the front teeth. During this time, your tongue is also touching the teeth. If you try to whistle with your mouth open, only air will come out of your mouth. But do you know that snakes don’t have front teeth, but they can emit a dangerous hissing sound.
Let’s see how. Scientists have answered the question related to the snake’s hiss. He said the snake hisses from the glottis which is connected to its respiratory system. Humans also have a glottis, which is used for speaking. When snakes breathe, this glottis opens. The glottis is connected to the snake’s trachea which connects directly to the lungs. Snakes have two lungs like humans, but only one works. The second lung is vestigial. That is to say, it disappears over time.
