 The phylogenetic relationships among the Strombidae have been mainly accessed in two different occasions, using two distinct methods.In a 2005 monograph, Simone proposed a cladogram (a tree of descent) based on an extensive morphoanatomical analysis of representatives of the Aporrhaidae, Strombidae, Xenophoridae, and Struthiolariidae.However, according to Simone, only "Strombus gracilior", "Strombus alatus", and "Strombus pugilis", the type species, remained within "Strombus".
