The living habits of crabs can be divided into "burrowing" and "seclusion". Cave dwelling refers to crabs that like to dig holes, while seclusion refers to crabs that live only in water grass depressions without digging holes. Why do crabs have such different living habits? It turns out that this has a lot to do with the living environment of crabs. In rivers and lakes where the water level fluctuates greatly, crabs usually choose to find a place to "stay" in order not to be washed away by the turbulent current. Crabs are very particular about finding caves, but after selection, they will complete the construction of caves in the shortest time. Crab caves are generally located between high and low water levels, and the steep bank with hard soil is selected (the hard soil makes the cave firm, and the steep bank is convenient for entering and leaving the cave and not easy to block the hole). Crabs generally twist their bodies first, push mud with their heads, dig with their claws, and scrape mud out of their holes with their feet. This cave is not very deep, just a shelter, and it will give up in case of danger or migration. In places with abundant aquatic plants and stable water level, crabs usually swim among them. Yangcheng Lake is a shallow grass lake, which is rich in aquatic plants and a large number of tributary waterways leading to the Yangtze River. It maintains a water level of about 2 meters all the year round, so Yangcheng Lake is very suitable for hairy crabs to live in seclusion. Hermit crabs have stronger metabolism, easier molting, faster growth and lighter body color than cave crabs, and are known as "clear water crabs". Cave crabs turn black, so they are called "black crabs". Push a wave of delicious hairy crabs: Yangcheng Lake hairy crabs of farmers in Jiangtan are delicious.
