Neuromuscular development in Patellogastropoda (Mollusca: Gastropoda) and its…

Within Gastropoda, limpets (Patellogastropoda) are considered the most basal branching taxon and its representatives are thus crucial for research into evolutionary questions. Here, we describe the development of the neuromuscular system in Lottia cf. kogamogai. In trochophore larvae, first serotoninlike immunoreactivity (lir) appears in the apical organ and in the prototroch nerve ring. The ar…
