Family Epitoniidae (the wentletraps)

Numerous species in the family Epitoniidae, commonly called wentletraps, are known from the Marshalls. Most or perhaps all known species are predators--probably more like parasites, since they appear to not kill their hosts--on various corals or anemones. Species are mostly small and white, and have a similar construction of fine axial ribs (costae) on a shiny white shell, making them somewhat difficult to identify. Several of our IDs are uncertain and many species remain unidentified. We welcome corrections at uwkwaj@yahoo.com. (Click on a thumbnail for pages with larger images.)
