Fun Facts

  • Unlike other snails, slipper snails cannot move.  They attach to something (usually a rock or another slipper snail) and spend their entire life there.
  • Start out as plankton and are not boys or girls until they attach to something.
  • Once they attach to something they become a boy.
  • Once another slipper shell attaches to them, that slipper shell becomes a boy and they become a girl.  This continues so that in their colony there are always boys and girls so they can reproduce.
  • Slipper shells eat plankton, so may end up eating slipper shell babies (larvae).
