The large housing snail eats filamentous algae, cyanobacteria turf, diatoms and plant detritus!
This species is found in the tidal zone and off the coast on coral reefs, especially on algae, coral sand and seaweed habitats
Adults prefer sandy algae areas; they can also be found on gravel, coral debris, smooth hard corals and beach rock bottoms. Rarely on soft bottoms of mud and/or silt.
Spawning occurs on a type of calcareous sand created by the fragmentation of coral reefs, including large quantities of calcareous skeletal remains of small molluscs and calcareous algae. Females deposit the egg mass on calcareous skeletal remains of small molluscs and calcareous algae
After 3-5 days, the eggs hatch into velils, which feed on phytoplankton; after 21 days they undergo a metamorphosis to the juvenile stage, where they remain buried in the sand and emerge in seagrass beds to feed; the adult animals return to the shallow coastal waters to spawn.
