Diverse colored proboscis extended to hunt fish. The panels show six species of cone snails that extended their proboscis in response to the presence of a fish. The species shown are: Top panel, left, Conus consors; right, Conus flavus. Middle panel, left, Conus circumcisus; right, Conus monachus. Bottom panel, left, Conus purpurascens; right, Conus tessulatus. Conus consors, Conus circumcisus and Conus monachus are species in the subgenus Pionoconus (see Figures 1 and 6, and Table I). Conus flavus is in the subgenus Phasmoconus, while Conus purpurascens is in the subgenus Chelyconus. Conus tessulatus is not in one of the specialized fish-hunting subgenera; it belongs to the subgenus Tessuliconus, which is primarily worm hunting, but will opportunistically attack fish, although it is often unable to pierce fish skin (see text).
