This marine species has a circumtropical distribution in the Atlantic, Indian, and Pacific Oceans.[1][2][3] The species is recorded recorded off South and East coast of South Africa at depths between 100 m and 500 m. [4]
Description
The maximum recorded shell length is 76 mm.[4]
The shell is thin and globose, with a prominent spire and rounded whorls, accompanied by a strongly indented suture. Its surface is adorned with well-defined, narrow spiral cords of alternating strength. In adult specimens, the outer lip is thickened and flares outward, with a finely toothed inner edge. The anterior end features a pronounced siphonal notch. [5]
The colour of the shell ranges from buff to pale brown, with the primary spiral cords being a darker brown. The spire may exhibit a subtle grey-blue tinge, while the tip of the spire (protoconch/apex), if present, is distinctly brown in color. [5]
