The body whorl bear clusters of 2 or more hollow, finger-like spines at regular intervals. Base color ranges from cream to pinkish-brown. Round aperture and interiorly nacreous (pearly). Operculums are multispiral and corneous, often calcified. Key identifiers include the unique spine structure (hollow and clustered), the prominent, flat body whorl with spines, and the overall sculpture and coloration, which differentiate Angariidae from similar turbinids

Dwelling from low tide levels down to approximately 45 m, typically associated with rocky substrates in coastal and reef environments
