There are two reasons: first, after encountering salt, razor clams will think that when the tide is high, they will get out of their nests and go back to the water. This illusion makes it easy for people to capture them. They usually live on the coast and can only be found on the shore after the low tide every day. Second: The main reason why they come out after meeting salt is that they are afraid of salt. Some ingredients in salt will suddenly change their living environment. After they come into contact with salt, their previous environment will change. They can't accept the change of their living environment, and they will want to escape from the changed environment, so they will run out of their nests and be caught. Some experienced fishermen will use clever methods to force them out with salt. Although the razor clam lives in the sea, because it is a mollusk, it can't stand the stimulation of high-concentration salt, and wants to use its own body to stop the salt from continuing to capture their nests. However, because they will keep crawling when they stop, people will find that they are on the verge of struggle and are easily captured by fishermen's ingenious methods. Now we all know the skills of catching razor clam. We can go to the seaside in our spare time on weekends and try to see if we can catch razor clam by ourselves. If you catch it successfully, you will have a full sense of accomplishment in your heart. But please pay attention to one thing. When we catch razor clam with salt, please pay attention to protect our environment. Remember to take away the salt bag or the salt water bottle after use, and don't throw it away everywhere. Cause environmental pollution.
