Necklace shell

Necklace shells are predator snails which prey on other molluscs. It is easy to recognize their victims. They grate a hole in the shell of the prey with their tongue. The hole on the one side is wider than on the other side. You hardly ever find living necklace shells on the beaches or dikes. Empty shells are strewn along all the beaches in the flood mark.

  • Distribution and habitat

    Necklace shells live dug into the sea floor, in waters up to 125 meters deep. You usually only find empty shells on the beach. Living animals do not usually come close to the shore.
