These are all common to very common species. The Liguus is widely used in the shellcraft industry, where it is called "candy snail". The Achatina is originally from East Africa, but has now spread to tropical locations around the world as a stowaway in agricultural products. Conus leopardus, when full grown, is one of the largest Conus species, reaching over 9 inches (225 mm) in length, and a weight of more than 2 pounds (900 grams).
