The rosy spindle cowry is an elongated species with an aperture along the entire length of the shell.

The shape is fusiform (cigar-shaped), with slender tapering ends and a slightly broader central section.

Its range extends from the east coast of Africa to Indonesia, southern Japan, New Caledonia and tropical Australia.

[2] The rosy spindle cowry is always associated with gorgonians; it utilises a range of species on which to live, including fan, whip and bush types.

The larvae are planktonic and need to settle on a suitable gorgonian host in order to continue their development.
