| Calliostoma tigris (Gmelin, 1791) |
Calliostoma tigris is a gastropod mollusc of the Family Calliostomatidae, endemic to New Zealand. It is found all around New Zealand, from low tide to 130 m under rock ledges in clear water.
The shell is large but rather thin, with concave early whorls, later becoming strongly convex. Sculpture of numerous fine granular spirals. The colour of the rather closely spaced dark narrow axial stripes is reddish-chestnut, on a creamy-white ground. The aperture is pale iridescent, and the operculum is horny and circular, multispiral, with a central nucleus.
Shell height is up to 77 mm, and width up to 76 mm.
