The cone snails are predators of the sea. They capture fish by injecting a venom into the prey that consists of a cocktail of different substances. The single components of the snails’ venom, so-called conopeptides, are known for their extraordinary pharmacological properties and potential. One example is Ziconotid (Prialt), a conopeptide that is prescribed as a pain medicine. That makes it one of the first medicines to contain substances from marine organisms.
