Calliostoma ticaonicum is known in the Marshalls from only a few specimens. Living specimens have been found on and apparently eating corals in the genera Stylaster and Distichopora, which are both hydrocorals like the Millepora eaten by Calliostoma fragum.
Below are some empty specimens. It is possible that we are lumping a couple of species under this name.
Below are the back sides of the two above, but it looks like I reversed the order of the specimens.
While similar, the morphology of those below seemed a bit different, but we have not found a better name yet. Probably it is just a variation.
