Shells of ''Distorsio reticularis'' can reach a length of . These shells are fusiform, inflated and roughly sculptured with axial and spiral ribs and low axial varices. Spire whorls are irregular, with a wavering suture. The aperture is narrow and distorted (hence the genus name), with strong teeth on the lips and a moderately developed callus. Siphonal canal is rather long and dorsally recurved. Operculum is corneous, irregularly ovate. tp://ftp.fao.org/docrep/fao/009/w7191e/w7191e48.pdf Distorsios at FAO.org/ref>
