See text The Ancillariidae is a taxonomic family of sea snails, marine gastropod molluscs in the superfamily Olivoidea.

They inhabit diverse marine environments, including coral reefs, sandy bottoms, and seagrass beds.

The shells exhibit a wide range of colors and patterns, from plain white or cream to vibrant and intricate designs.

[4][5] Ancillariidae snails are primarily nocturnal, being active at night to feed on algae, detritus, and small invertebrates.

The larvae develop into planktonic forms, drifting in ocean currents until they settle on the substrate and undergo metamorphosis into adults.
