Sea mussels don't die. Mussels will die.

Sea mussels can survive after the pearls are taken out of their bodies, but river mussels have a hard time surviving after the pearls are taken out of their bodies because sea mussels produce only one pearl inside, and as long as the pearls are carefully dug up they won't hurt it, but river mussels produce more pearls, and in order to completely take these pearls out we have to open the mussel up completely, which makes it prone to a deadly situation.

Characteristics of pearls:

Pearls are an ancient organic gemstone, mainly produced in nacreous shellfish and mother-of-pearl mollusks. Pearls for shellfish endocrine action and generated by the mineral beads containing calcium carbonate, by a large number of tiny aragonite crystals assembled. Rich in variety, different shapes, colorful.

Mussels habits:

Mussels are aquatic benthic animals, perennial habitat in rivers, lakes, ponds and other bodies of water in the mud, camping buried life. In winter, the entire body of the mussel buried in the sediment, only the back end of the shell for breathing and feeding, in summer, most of the exposed outside the sediment. Depending on the axe foot movement, the range of activities is narrow.

Different species of mussels have different environmental requirements, pleated crown mussels and back angle toothless mussels like to inhabit in slow-moving or static waters; triangular sail mussels, Li mussels, pond butterfly mussels like to live in clear water, fast-moving, hard substrate in muddy bottom waters.
