Abstract: The distribution of Cypraea in two habitat 'zones at Puako reef on
the island of Hawaii was examined. Three species, Cypraea gaskoini, C. cicercula,
and C. scurra, were found only in the reef face stud y site, and two species,
C. poraria and C. caputserpentis, were found only in the reef top study site. Active
individuals of all species were distributed nonrandomly with respect to substrate
type. For reef face species the distribution of individuals appeared to be related
to diet , with sponge the major dietary component of each of four reef face
species. One cowrie was found to be prey specific for one species of sponge , and
the distribution of C. gaskoini appeared to be dependent on the distribution of its
prey sponge.
