FVamide and FLamide immunoreactivity in annelid and mollusc larvae. Immunostainings with the FVamide antibody (red) counterstained for acetylated tubulin (acTub, white) in (A) an early Capitella larva, anterior view, (B) a late Capitella larva, ventral view, (C) a Pecten veliger larva, lateral view, and (D, E) a Phestilla larva, ventral (D) and dorsal (E) views. Immunostainings with the FLamide antibody (red) counterstained for acetylated tubulin (acTub, white) in (F) a late Capitella larva, ventral view, and (G) a Phestilla larva, ventral view. Arrows in (C) and (E) point at projections that run along the ciliated velum of Pecten and the ciliated foot of Phestilla. Scale bars: 50 μm. cbn, ciliary band nerve; cg, cerebral ganglion; cpg, cerebropleural ganglion; DIC, differential interference contrast; vg, visceral ganglion.
