Mass spectrometric characterization of the neuropeptidome of the ghost crab Ocypode ceratophthalma (Brachyura, Ocypodidae)

► The first description of a peptidome from a terrestrial crustacean. ► 156 peptides, representing 15 distinct families, characterized. ► ∼40% of the identified peptides are novel. ► The peptidome is the largest thus far identified via MS from any crustacean. ► Data provide a framework for future physiological investigations.
