The Vermetidae, the worm snails or worm shells, are a taxonomic family of small to medium-sized sea snails, marine gastropod molluscs in the clade Littorinimorpha. [1] The shells of species in the family Vermetidae are extremely irregular, and do not resemble the average snail shell, hence the common name "worm shells" or "worm snails".
These sessile snails extrude a mucous net for feeding, which negatively affects both the coral growth and morphology, reducing their rate of survival. Trapezia rufopunctata have been observed cleaning the corals of vermetid mucus while feeding on the coral itself. They feed by first massaging the coral tissue with their legs, which produces a ...

Nearly all of these are genera of shelled forms, since it is relatively rare for gastropods without a shell ( sea slugs ) to leave any recognizable traces.
However, they are also known to eat algae, seagrass, and other small creatures, such as sea slugs or sea snails. The sponges that make up a large percentage of their diet are actually subject to scientific study. As the sea bunny feeds on highly toxic sea sponges, they steal these toxins and utilize them as a defense mechanism.
