How does one delimit individuals with a morphology that is intermediate between that of two species? Do these individuals belong to one or the other species or are they hybrids? In their paper, Unraveling Cryptic Morphological Diversity in a Marine Snail Species Complex Using Nuclear Genomic Data, Mollusk Division PhD student Peter Cerda and coauthors used analyses of patterns of genetic variation at nuclear gene regions to reveal that cone snails that appear to be morphological intermediates between Conus lividus and Conus sanguinolentus are in fact members of C. sanguinolentus. This result confirms that C. sanguinolentus has a wider range in the Indo-West Pacific than previously thought and prompts the question as to why individuals of C. sanguinolentus in the Hawaiian Archipelago only have the intermediate morphology.
