This website is dedicated to species within Triphoroidea. Triphoroidea is a groep of marine Molluscs, currently containing three families: Cerithiopsidae, Newtoniellidae and Triphoridae. The focus is especially upon Triphoridae, however in some cases information of species from the other two families is also available. It has often been the case that a species was described as a Triphoridae, but turning out to belong to one of the other families, or vice versa. The goal of this website is to represent all known extant and fossil species of Triphoridae, all relevant published and distributional information.
