Common name : bubble snails

Aspect : robust, ovate shells that are inflated and globular, resembling bubbles; surface is smooth or finely sculptured, with a low spire and a large body whorl that dominates the overall shape; aperture is wide and oval, often nearly as broad as the shell's height, and the outer lip is simple and thin; colors vary from white or cream to brown, pink, or reddish-brown; size range from 20–60 mm

Feeding : herbivorous (microscopic algae, detritus, and fine organic particles)

Environment : shallow marine waters worldwide, predominantly in tropical and subtropical regions, but with representatives extending into temperate zones (e.g., the Mediterranean and California coasts); prefer soft substrates such as sand, mud, or fine gravel in intertidal zones, seagrass beds, mangroves, and shallow subtidal areas up to 20–30 m depth
