Venomics studies are systematic analyses of venom composition and evolution that apply omics technologies to venomous species. The field combines proteomics, genomics, transcriptomics, and bioinformatics to identify toxins, catalog venom components, and compare venom across taxa. It sits within toxinology and chemical biology.

Methodology involves profiling venom at multiple levels: toxin gene expression in gland transcriptomes, protein composition in venom proteomics, and reference genomes that illuminate toxin gene families. Integrated pipelines use LC-MS/MS, high-throughput sequencing, and bioinformatic annotation to map peptides and proteins to functional categories.

Scope covers a broad range of venomous animals, including snakes, scorpions, spiders, cone snails, and lizards. Researchers compare venom arsenals to understand diversity, convergent evolution of toxin families, and ecological drivers of venom optimization.

Applications include informing antivenom development, guiding the discovery of peptide therapeutics, and improving diagnostics and quality control for venom-derived medicines. Venomics data also support ecological and evolutionary studies by linking composition to prey use and habitat.

Challenges include incomplete reference genomes, intrapopulation variation, and geographic or ontogenetic changes in venom. Standardization of methods, open data sharing, and ethical considerations are ongoing priorities to enhance reproducibility and cross-study comparability.
