Add to basketThe osphradium is larger and more complex in Conus, a large and taxonomically difficult genus, than in other prosobranch gastropods. We examined intra- and interspecific variation in external anatomical characters of this major chemoreceptor organ, how these relate to ecological characteristics, and the potential of the osphradi…um to aid taxonomic differentiation, among 22 species of Conus. Six quantitative characters convey the main features of the Conus osphradium: its area, width-length ratio, curvature, orientation relative to the animal's anterior-posterior axis, density of sensory leaflets, and number of digitiform ridges on sensory leaflets. Species in 85% of pairwise comparisons differed significantly with respect to at least one variable. Multivariate discriminant function analysis successfully differentiated other species. Osphradium size relative to body size varied significantly with habitat type, and number of digitiform ridges varied with food type, but other characters were independent of ecological attributes and may potentially be useful in phylogenetic reconstruction. 15 pp., 6 figs, 4 tabs, gr. 8.
