Ecology
Clithon oualaniense is a eurybiotic species.[7] It inhabits soft bottoms of intertidal habitats.[7] It can occur in high density, for example 347 snails per m² was recorded, that correspond to the biomass of 30.6 g per m².[7] It also inhabits sea grass bed with Zostera japonica.[8] The activity of Clithon oualaniense is diurnal; snails are active during the daytime and inactive at night.[8] It bury itself into the mud, when the tide is high, probably to avoid water predators.[9] They are on the surface feeding and mating when the tide is low.[9]
Clithon oualaniense is herbivorous, feeding of microalgae and on detritus.[8]
