Cover Story (view full-size image): Some snake venoms have been found to have prey-specific potencies, yet the role of diet breadth on venom potencies has yet to be tested on large scales. Using data from 100 snake species, this study shows how the evolution of prey-specific potencies is dependent on the taxonomic richness or breadth of a snakes’ diet rather than species richness. This indicates that the physiological diversity of a species’ diet is an important driver of the evolution of generalist venom potencies and that species’ venoms with taxonomically rich diets may be better equipped for incapacitating novel prey species within changing environments.
