General Information

• a lamellibranch mollusk with a dark shell
• found in two completely different places: silt and gravel 
• In the former case, you have to fish for them in holes, that is by digging under the figure-8 shaped holes left by the clams in the silt. Otherwise, collect them near rocks, places that are both stony and sandy, and scrape the bottom with a claw at low tide.
