The ontogeny of neuropeptide-expressing neurons during larval development of the crustacean central nervous system is as yet poorly understood. Recently, homologues of the molluscan neuropeptide FMRFamide have been isolated from the central nervous system of adult crustaceans. In order to identify sets of neurons which might express FMRFamide-related neuropeptides and to follow their development, whole mount preparations of the brain and ventral nerve cord of laboratory-reared spider crab

The distribution and morphology of FMRFamide-like immunoreactive neurons, their primary neurites, and neuropils were mapped throughout development of the stages zoea I and zoea 2. Ontogenetic alterations in the staining pattern were recorded and the results compared to the distribution of FMRFamide-like immunoreactivity in other crustaceans.
