The sea whelk, scientifically known as the cone snail, looks very similar to the freshwater whelk and can be easily misidentified. The main difference between them is that the cone snail lives in the ocean and is a normal edible seafood; the nail snail grows in freshwater lakes and is an intermediate host for bloodsucker larvae, and should not be eaten.
The snail in the sea water is actually a kind of marine organism called cone snail, belonging to the cone snail family. Because the appearance is very similar to the snail so it is easy to be mistaken, the cone snail is mostly found in Taiwan and Fujian coastal areas, is a common seafood.
The freshwater whelk is an amphibious mollusk, with female and male species, mostly found in lakes. The freshwater whelk is the main intermediate host of the Japanese bloodsucker, and is not suitable for consumption.
