Coluzea radialis, common name the Benguela pagoda shell, is a species of large sea snail, marine gastropod mollusk in the family Columbariidae.

[2] The white shell is relatively thin, with a long, slender, and straight siphonal canal.

The periphery features a spiral row of bluntly triangular spines, ranging from 15 to 50 on the body whorl.

The rest of the shell is sculpted with spiral cords, which are most prominent below the periphery and along the base of the siphonal canal.

[2] This marine species is endemic to South Africa and occurs off the West coast, off Atlantic Cape region (Alexander Bay to Cape Point), at depths between 160 m and 420 m. [2]
