How do sharks predict storms

Sharks can feel small changes in air pressure and predict storms

Researchers found that sharks can feel small changes in air pressure when they are in storm warning, and swim deeper into the ocean in search of a safer place to live. Sharks' sensitivity to air pressure was first noticed in 200 1 year, when Hurricane Gabriel was approaching Florida, and many young blacktip sharks fled the shallow coastline.

Lauren smith, a marine biology major at the University of Aberdeen, is currently conducting further research on this feature of sharks in the Bahamas. She said: "The inner ear structure of sharks is very similar to that of humans. When we fly, with the increase of altitude, the air pressure will expand our eardrums, and the same thing will happen to sharks. " She also said: "There is a nerve in the shark's inner ear that is directly connected to the brain. This nerve can transmit information about changes in air pressure, so they can respond. "

Other animals that can predict the weather.

Frog: In spring and summer, frogs cry loudly and densely, which indicates that it will rain soon.

2. Swallow: The weather turns bad. When it rains, the air humidity increases, and the wings of insects become soft because of the humidity, so they can't fly high. Swallows fly low to catch insects.

3. Sparrows: In summer and autumn, the weather is sultry and the air is humid. When the sparrow feels itchy, it flies to the shallow water area to take a bath to dissipate heat, indicating that it will be rainy in a day or two; If a large group of sparrows take a bath, it indicates that there will be heavy rain in the future.
