Common name: Eulimid Snails

Scientific name: Eulimidae

Eulimid snails are a family of small, parasitic gastropods known for their symbiotic relationships with echinoderms, particularly sea stars and sea urchins. They are characterized by their elongated, often transparent or pale shells. In the aquarium, they are rarely noticed due to their size and lifestyle. Eulimids can be beneficial by controlling echinoderm populations, but their presence is often an indicator of a well-established system with a diverse invertebrate community.
