The blood clam is a kind of shellfish, and its habits and appearance will have some differences between winter and summer. In winter, blood arks usually enter a dormant state, slowing down their metabolism and activities. They will close their shells and fall into a deep sleep without actively foraging for food. This is because the water temperature in winter is low and food resources are relatively few, so blood pincers take this approach to conserve energy and protect themselves. In the summer, as the water temperature rises and food becomes more abundant, blood clam will resume their activities. They will open their shells and stretch out enough to forage for food. Summer is the breeding season for blood arks, and they will actively search for mates and reproduce. Blood arks are a type of shellfish, also known as blood clams and blood clams, which are mollusks in the ocean. They live on sandy beaches or mud flats and have red or dark red shells, hence the name blood clam. The meat of blood clams is delicious and is often used in cooking, especially in seafood cuisine, where it is widely used.
