The story of the heroic little jellyfish
The little jellyfish said anxiously, "I didn't lie." I have a knot on my tentacle. There is a listening stone in the knot, and you can hear this infrasound. Before the storm surge, the friction between air and sea water will produce a infrasound that humans and ordinary animals can't hear. Only I can feel it. Please believe me once. " The creatures in the sea heard the little jellyfish say this and hid in succession. After a while, the storm surge came and the sea was rough. After the sea calm returned to normal, everyone thanked the little jellyfish and called it a hero.
Comment on the story of hero jellyfish: jellyfish is a kind of marine life. They live in the ocean. Jellyfish are beautiful in shape, but they have another function, that is, they can predict storms at sea. The reason why the storm can be predicted is that there is a small listening stone in the ball near the "umbrella" of the jellyfish, which seems to be the "ear" of the jellyfish. Infrasound waves generated by the friction between waves and air will impact the auditory stone and the nerve receptors around * * *, allowing jellyfish to capture the sound of the storm more than ten hours ago. As a result, they seem to have received orders and suddenly sank into the depths of the ocean to avoid being smashed by the huge waves aroused by the storm.
