Update 1: Not a good question, but your answer is really good!

1. Taiwan Province people call mussels the green mouths of China and Hongkong.

The scientific name is Qingkou. Qingkou has two shells.

There is a blue edge on the edge of the shell.

Hence the name Qingkou. 2. Qingkou lives in the sea.

There are two shells.

Can't float on the water.

Can only be based on plankton and aquatic plants on the seabed. When catching, there will be caught aquatic plants on the edge of mussels, which should be cleaned when cooking. These aquatic plants sometimes have roots. 3. When diving, you can see that the roots of stuttering aquatic plants grow in the sediment.

Qingkou is a mollusk, a multicellular animal, and each cell has a cell membrane. I hope I can help you! You don't have to choose me as the best, but please don't remove it for no reason. 2008-10-25 09:10: 36 Supplement: It suits your attitude of seeking knowledge. Did you see any aquatic plants beside Qingkou when diving? Or did you see it in a fishing net? Or listen to friends in Taiwan Province province call it mussel, which involves a wide range of knowledge. You can see the software of aquatic plants going deep into Qingkou. There are two ideas. One is green mouth eating. Second, aquatic plants and green mouths are born (this should be checked), corals will be born together with aquatic plants, aquatic plants will live in corals to carry out photosynthesis and supply coral with nutrients, and aquatic plants will starve to death if they cover the sun. Very interesting and realistic question. Good question.
