This study uses morphological and immunocytochemical techniques to describe the shell, sensory, muscle, and nervous systems of the parasitic glochidial larvae of the freshwater mussel Buldowskia suifunica. The central result is a detailed characterization of these anatomical features across three developmental stages, concluding that the glochidial nervous system differs from that of planktotrophic marine mollusk larvae.
This integrative morphological study examined glochidia (parasitic larvae) of the freshwater mussel Buldowskia suifunica from the Primorsky Territory, Russia. Key findings include asynchronous development of larvae from the same gill, a complex FMRFamidergic nervous system with basal cells and anterior neurons, and the presence of only four 5-HT-immunoreactive neurons. The study notes that the glochidial nervous system, lacking an apical organ, differs from that of planktotrophic marine mollusk larvae. The work provides anatomical data relevant to understanding freshwater mussel larval biology and potential taxonomic differentiation.
