What behaviors of living things are related to the weather?

Fishermen along the coast know that fish and jellyfish living along the coast swim to the sea in batches, which indicates that a storm is coming. Jellyfish is an ancient coelenterate that floated in the ocean as early as 500 million years ago. This low-level animal has always had the instinct to predict storms. Whenever there is a storm warning, it will swim to the sea to take refuge. The reason is that infrasound generated by the friction between air and waves has always been a prelude to storm warning. This infrasound is inaudible to human ears, but jellyfish are very sensitive to it-bionic technology experts have found that there is a thin handle in the ear cavity of jellyfish, and there is a small ball on the handle with a small listening stone in it. When the infrasound before the storm hit the audiostone in the jellyfish's ear, the audiostone stimulated the nerve receptors on the ball wall, so the jellyfish heard the rumble of the coming storm. According to the structure and function of jellyfish ears, bionics experts designed a jellyfish ear storm predictor, which accurately simulated the organs of jellyfish that felt infrasound. This instrument is installed on the front deck of the ship. When it receives the infrasound wave of the storm, the horn that can rotate 360 will stop rotating by itself, and the direction it refers to is the direction of the storm. The reading on the indicator can show the intensity of the storm. This forecaster can forecast storms 15 hours in advance, which is of great significance to navigation and fishery safety.
