They might work on their own (they make up only two percent of the total venom, and this could explain why many venomous snakes inject far more venom than is needed to kill their normally small meals), or they might interact with other chemicals in the prey's body to create cues for the snakes to follow. Mackessy and his team are exploring these questions in new experiments now.
