Morphology of the juvenile of Terebratalia transversa (2 days after metamorphosis), visualized with light microscopy (A) and CLSM (B, D–I). A Micrograph of the entire animal. B Frontal section through the median part of animal, cell nuclei visualized with DAPI staining. C Schematic drawing of the anatomy of juvenile in dorso-ventral (top) and lateral (bottom) views, musculature in green, tyrosinated-tubulin immunoreactive nervous system in red, acetylated-tubulin immunoreactive structures in orange (mantle margin ciliation not shown for clarity). D, G Musculature visualized with F-actin phalloidin staining, arrowheads in D point to the ventral mantle margin muscles. E, J Tyrosinated-tubulin immunoreactivity. F, I acetylated-tubulin immunoreactivity. H Transverse section through the nephrostome, cell nuclei visualized with DAPI in cyan, acetylated-tubulin immunoreactivity in yellow. A–F Dorso-ventral view, anterior to the top. G Lateral view, anterior to the left, dorsal to the top. I Virtual transverse section through the middle part of animal, dorsal to the top.
