a

The diverse ion channel targets of venom peptides involved in prey capture that have been characterized are shown. Examples of peptides that target these sites from two species in the Pionoconus clade (Conus magus and Conus striatus) and two species in the Chelyconus clade (Conus purpurascens and Conus ermineus) are given in the two columns indicated. Several α-conotoxins target the α/δ interface of the neuromuscular nAChR [68], while these αA-conotoxins target the α/δ and α/γ interfaces of the neuromuscular nAChR [59].

b

Names of peptides are abbreviated. The amino acid sequence of each peptide is given in the references provided. An overview of the structures, mechanisms and nomenclature of these peptides is Terlau et al., 2004 [69].

c

Peptides from Conus magus have M in their abbreviated name (α-MI, μ-MIIIA, etc.), while Conus striatus peptides have S, Conus purpurascens, P and Conus ermineus, E.
