After crawling on the sand, the jade snail often leaves a clear trail due to the role of the forefeet hoeing the sand, and collectors can follow this line of footprints to find it after low tide. The shell of the jade snail is spherical or gyroscopic, the spiral part is short, the body of the conch layer is expanded, the shell surface is smooth or has a slender spiral engraving. Spotted jade snail's shell surface is covered with purple-brown or yellow-brown spots, and most of its meat is edible, but because of its own carnivorous animal, one of the enemies of the sea-coast culture shellfish, it is in the prey of bivalve shellfish or small fish, they first drilled holes in these prey, and then inserted their muzzles into the holes and ate the prey.
