Figure 2

Conus geographus foraging. In the top figure, the snail is moving towards fish that it has detected through its intake siphon. It has opened its rostrum, and is secreting a subset of venom components. Middle panel, The snail begins to engulf a fish; the fish has become quiescent and sufficiently disabled so that it is unable to swim away. Bottom panel, the snail has closed off its rostrum, fish are now trapped inside. The snail will then sting the fish and inject a small amount of venom that causes an irreversible block of neuromuscular transmission. The eye-stalk of the snail is visible on the middle and bottom panels; the snail can detect light, but the chemosensory system is primarily used to detect and locate fish prey.
