In eastern Australia there are seven to nine deeply indented ribs in each whorl with clefts of a similar width between them, sculptured with further fine riblets.

Specimens gathered from New South Wales with deep ridges were kept in a still water aquarium for three years during which time the new shell growth was at first shallowly indented and later was smooth.

[2] The colour of the shell is generally creamy white or grey, often with a thin yellowish line round the margin of the lip.

Prey species include the sea snails Lunella torquata,[2] Cronia avellana and Pyrene bidentata, and the mussel Septifer bilocularis.

This is in contrast to the mulberry whelk Morula marginalba which shares the same habitat but remains in an area where there are both crevices in which to hide and prey species on which to feed.
