Pacific oysters are a species of oyster native to the western coast of North America and parts of Asia. They are known for their distinctive, irregularly shaped shells, which can vary in color from gray to greenish-brown. These oysters thrive in intertidal zones and estuaries, where they attach themselves to rocks or other surfaces. Pacific oysters are popular in seafood cuisine and are often enjoyed raw, grilled, or baked. They are also farmed extensively due to their fast growth rate and ability to adapt to various environments. Their cultivation supports local economies and contributes to marine ecosystem health.
