The evolutionarily unique and ecologically diverse family Conidae presents fundamental opportunities for marine pharmacology research and drug discovery.The focus of this investigation is to summarize the worldwide distribution of Conus and their species diversity with special reference to the Indian coast.In addition,this study will contribute to understanding the structural properties of conotoxin and therapeutic application of Conus venom peptides.Cone snails can inject a mix of various conotoxins and these venoms are their major weapon for prey capture,and may also have other biological purposes,and some of these conotoxins fatal to humans.Conns venoms contain a remarkable diversity of pharmacologically active small peptides;their targets are an iron channel and receptors in the neuromuscular system.Interspecific divergence is pronounced in venom peptide genes,which is generally attributed to their species specific biotic interactions.There is a notable interspecific divergence observed in venom peptide genes,which can be justified as of biotic interactions that stipulate species peculiar habitat and ecology of cone snails.There are several conopeptides used in clinical trials and one peptide(Ziconotide) has received FDA approval for treatment of pain.This perspective provides a comprehensive overview of the distribution of cone shells and focus on the molecular approach in documenting their taxonomy and diversity with special reference to geographic distribution of Indian cone snails,structure and properties of conopeptide and their pharmacological targets and future directions.
