Venomous animals have always been intriguing, whether they scare or captivate people. For scientists, they have always been fascinating creatures not only for their biological aspects, but also for the power of their venom. Venomous creatures can be found in virtually all major groups of terrestrial and marine life with more than a 100,000 species spread throughout the world. Scientists have always wondered what can be so powerful in such a tiny drop of venom that can cause such damage and possibly kill. Only quite recently, in comparison to the millions of years of evolution of venomous animals, have scientists started in-depth investigations on how such destructive power could be used in a constructive manner. Progressively, the number of venom components studied increased and so did their potential as drug candidates for healthcare through pharmacological research and development.
