This variation provides a powerful framework for investigating ecological and evolutionary processes. Here, we offer a forward-looking synthesis of snake venom diversity that proposes new research directions and highlights how venom variation can illuminate eco-evolutionary dynamics across biological scales. We review evidence for 10 key contexts in which venom variation arises, including within-population differences, sexual dimorphism, geographic structuring, ontogenetic shifts, seasonal changes, interspecific divergence, hybridization, convergent evolution, prey specificity, and venom resistance. Together, these processes demonstrate that venom phenotypes are shaped by interacting selective pressures such as trophic ecology, predator\u2013prey coevolution, environmental heterogeneity, and gene flow. While phylogenetic history establishes broad toxin composition patterns, ecological factors frequently drive rapid and repeated shifts in venom phenotype. We further outline the historical development of venom research, from early descriptive studies to modern integrative approaches enabled by advances in proteomics, transcriptomics, genomics, and functional assays. These methodological innovations increasingly allow venom composition to be linked directly to ecological performance and evolutionary outcomes. Despite this progress, major gaps remain, including limited taxonomic coverage, incomplete integration of ecological data, and insufficient experimental tests of adaptive hypotheses. Future research combining molecular, functional, and field-based approaches will be essential for resolving the mechanisms that generate and maintain venom diversity. As complex traits shaped by interacting ecological and evolutionary forces, snake venoms provide an exceptional model system for understanding how selection, constraint, and environmental context interact to produce phenotypic diversity across time and space.<\/jats:p>","DOI":"10.1093\/icb\/icag056","type":"journal-article","created":{"date-parts":[[2026,5,26]],"date-time":"2026-05-26T11:19:37Z","timestamp":1779794377000},"source":"Crossref","is-referenced-by-count":2,"title":["Venom
