When Darwin traveled around the world on the "Begger" warship, it was incredible to see countless spiders falling from the sea on the deck of the ship. Since then, how spiders can move at sea has always been seen as a mystery to chemistry. Japan’s Miyagi University of Education recently issued a communique stating that an international team of researchers at the school found that when the spider was blown away by the wind and fell to the surface of the water, the feet and abdomen would be lifted up like a sail, thus The body uses the wind to sail on the surface of the water like a sailboat. This shows that it was wrong to think that spiders would drown in lakes or in the sea. The team, consisting of researchers from Japan, the United Kingdom, and Spain, experimented with 21 spiders floating in the lab's sink and then blowing them around, revealing that many species of spiders, such as the canopy spider, are widely distributed around the world. After the wind, the feet will be lifted or the abdomen will be lifted from the head down, and the wind will slide on the surface of the water. Sometimes, when the water slides, the spider silk is lowered like an anchor to reduce the speed. However, these spiders do not take this action when they are blown by the wind on the ground. The team pointed out that the spider's feet are waterproof and can walk on the surface of the water depending on the surface tension of the water, but there are ripples when walking, which is easy to be found by the fish. The spider "sail sailing" relies on wind power, which not only saves physical strength, but also is not easily found by natural enemies. It is a safe way to move.
