Cover Story: Venomous fish have been relatively poorly studied, with respect to both the composition and evolution of their venoms. This review attempts to summarize what is known about the evolution of fish venoms from an ecological perspective and, where possible, to place it in the context of the evolutionary ecology of other venomous/toxic taxa. It delves into the consequences and adaptations associated with evolving a venom system from aposematism and mimicry to niche ecology, coevolution, and natural enemy interactions. Understanding these broad ecological facets can shed more light on other areas of toxinology, with applications across multiple disciplinary fields. View this paper.
