Semischematic representations of the neurulation processes in different deuterostome taxa. A. Neurulation in enteropneusts (Saccoglossus kowalevskii). B. Neurulation in ascidians (Boltenia villosa, Molgula occidentalis). C. Neurulation in cephalochordates (Branchiostoma belcheri and B. lanceolatum). D. Neurulation in blue amphibians (Xenopus laevis). Light blue = epidermis; green = endoderm and endodermally derived notochord; red = mesoderm; yellow = nervous tissue. Abbreviations: fi = fin; fic = fin chamber; nc = neural canal. A: Modified from [324]; B: Modified from [325, 326], C: Modified from [324, 327]; D: Modified from [328].
