Abstract: Like other members of its genus, Conus californicus has a highly evolved venom apparatus with which it injects paralyzing venom into its prey through a modified radula tooth. Although much research is being conducted on the venom itself, relatively little is known about the biology behind the snail's ability to inject the venom. The venom duct, radula sac and teeth were characterized in terms of anatomy, physiology and chemistry. The passageway between the venom duct and proboscis is a complex branching structure lined by a unique secretory cell type. Evidence from a combination of all methods used suggests that there are similar active peptides in the teeth as in the duct, leading to the possibility that the teeth are pre-loaded with venom.
