👉 Ophiucus, also known as the "oyster fish," is a type of freshwater fish native to China and Japan. They are known for their large size and distinctive shell patterns, which include a series of overlapping rings on the surface. These rings are thought to be used in communication by ophiucids to communicate with each other. Ophiucus are typically found in freshwater habitats such as streams, rivers, and lakes, and they can grow up to 15 feet long
