The sequence of a 16S rDNA gene segment in mitochondrial DNA from seven Conus species were determined. The resulting phylogenetic tree indicates that Conus californicus, a non-selective predator is most unrelated to the other Conus species. Three putative fish-hunting species were found to be more closely related to each other, despite different shell morphology and geographical distribution. The results are consistent with several lineages of vermivorous Conus: the two worm-hunting species, C. distans and C. rattus do not appear more closely related to each other than to other Conus analyzed. The data provide preliminary evidence consistent with the fish-hunting species being more closely related to the snail-hunting Conus bandanus than to any of the worm-hunting species
