Onchidiidae are a family of small, air-breathing sea slugs. They are shell-less marine pulmonate gastropod molluscs.
These animals are quite unusual in that they are emphatically not opisthobranchs with gills, as are almost all of the sea slugs. Instead these creatures are pulmonates. They are more closely related to air-breathing land and freshwater snails and slugs than they are to most other sea snails and sea slugs.
Slugs in this family make and use love darts made of chitin.
Habitat
They are found in the intertidal zone on rocky coasts.
Life habits
They breathe air and feed during low tide, when the water recedes.
