Term
Marine cone snails are predatory molluscs that produce an efficient
venom, called conotoxin. This venom allows them to successfully
capture worms and fish as their primary food sources. Conotoxins
have the capacity to inhibit specifically the acetylcholine receptors
in higher animals. Thus, conotoxin inhibits receptors that are located:
