Caducifer truncatus (Hinds, 1844)

Caducifer truncatus is rare in the Marshalls. We know of the two living specimens figured here, plus a couple of empty shells. Both live ones were were juveniles and were found under rocks, one on a lagoon reef and the other on the seaward reef. Mature shells have been found in reef quarries and in rubble on the seaward reef. As adults, the spire is always broken off, even more than the specimen in the third and fourth photos.

Below is the empty shell of a full adult showing typical spire breakage.
