Male stolon (ventral view, anterior up) of the annelid, Proceraea sp., fluorescently stained for acetylated tubulin (green), serotonin (yellow), F-actin (red; phalloidin), and nuclei (blue; DAPI).  Confocal z-stacks were viewed as maximum  projections and tiled together to cover the entirety of the animal (body length approximately 7.5 mm).
