nmtumu
Oysters are soft-bodied mollusks with rough, oval-shaped shells in shades of gray or brownish white. They range from 5 to 30 centimeters in length and can live up to 100 years. Oysters breathe and feed by filtering water through their gills. As a defense mechanism, they sometimes produce pearls inside their shells.
