Neuropeptides are vital signaling molecules involved in neural communication, hormonal regulation, and stress response across diverse taxa. Despite their critical roles, neuropeptide research remains challenging due to low abundance, complex post-translational modifications (PTMs), dynamic expression patterns. Mass spectrometry (MS)-based neuropeptidomics has revolutionized peptide identification quantification, enabling the high-throughput characterization of neuropeptides PTMs. However, complexity vertebrate networks poses significant challenges for functional studies. Invertebrate models, such as Cancer borealis, Drosophila melanogaster, Caenorhabditis elegans, offer simplified circuits, well-characterized systems, experimental tools elucidating roles neuropeptides. These models have revealed conserved families, including allatostatins, RFamides, tachykinin-related peptides, whose homologues regulate analogous physiological functions. Recent advancements MS techniques, ion mobility MALDI imaging, further enhanced spatial temporal resolution analysis, allowing insights into systems. not only expands our understanding functions but also informs translational applications development peptide-based therapeutics. This review highlights utility invertebrate discovery, emphasizing contributions uncovering fundamental biological principles relevance
