Why do clams spray water?

Clams can spray water, especially clams. Clams don't spray water aimlessly, but spray water with a certain purpose. Clams spray water for many purposes. Clams generally live in water, while wild clams generally live in the ocean and are very common in shallow water.

When they need to move in the water, they will spray water and move forward with the help of water, which is more convenient. Sometimes, they spray water because they want to resist enemy attacks. When they feel threatened by other creatures, they may spray water to protect themselves.

In addition, clams sometimes feed and excrete by extending water pipes. Therefore, spraying water is more important, and it is an indispensable activity of clam.

Generally, the flower nail will spit sand after soaking in salt water for a period of time. It may not open its mouth for the following reasons:

1. First of all, it may be because the salt is not completely melted and the salt in the water is insufficient. You need to prepare a large basin of water, dissolve the salt in the water, and then immerse the flower nail in the water to let the flower nail spit sand. The amount of salt should be sufficient, not just a little. It is best to use the ratio of salt to water of 3: 1, so that the concentration of brine is enough.

2. Secondly, it may be that the soaking time is not enough. Generally speaking, it takes more than three hours to soak in flowers. It is possible that the flower nail does not spit sand because the soaking time is too short to make it spit sand.

3. Finally, it may be because this flower nail is tenacious and can't be soaked. This is also the case. Generally, this kind of flower nail has less sand and can be directly used for cooking or cooking.
