Where is scallop found?

Could you please elaborate on the distribution of scallops? Are they found in specific regions of the world, or do they have a more widespread presence? Are there any particular habitats or ecosystems where scallops thrive? Additionally, are there any notable differences in the types of scallops found in different locations, such as variations in size, color, or taste? I'm curious to learn more about the natural environment and geography associated with these fascinating shellfish.
