Development of FMRFamide-like (green) and acetylated tubulin-like (red) immunoreactivity in P. dumerilii. Three-segmented errant juvenile worm (a-b), cephalic metamorphosis (c-e), small atokous worm (f-h). a: 16 dpf, FMRF-lir innervation of the parapodium (arrows). b: 16 dpf, FMRF-lir innervation of the pygidium (arrows). c-e: 6-segmented juvenile, 20 dpf; ventral view showing FMRFa-lir innervation of the body (c); left lateral (d) and ventral (e) view on the anterior body part showing FMRFa-lir immunoreactivity in the brain (br), circumesophageal connectives (cc), stomatogastric nerves (sn), subesophageal ganglion (seg), pharynx (ph), antennal nerves (an), segmental nerves (arrows) and ventral nerve cord (vnc). See additional movie [Additional file 1] for 3D rotatable reconstruction. f-h: 10-segmented juvenile, 25 dpf, ventral view showing FMRFa-lir innervation of the body (f); left lateral (g) and ventral (h) view on the anterior body part showing FMRFa-lir immunoreactivity in the brain (br), circumesophageal connectives (cc), stomatogastric nerves (sn), subesophageal ganglion (seg), pharynx (ph), and ventral nerve cord (vnc); j - jaws.
