Progressing embryo morphology during N. vectensis development. The table estimates the time of development at two different temperatures for the stages until the late planula. Table entries indicate the hours after fertilization derived from [11, 18, 21]. The annotations in the schematic morphologies are guidelines for researchers to describe expression domains in their hybridization images. AnHe = animal hemisphere, VeHe = vegetal hemisphere, An = animal pole, Cd = central domain, Cr = central ring, Er = external ring, Ve = vegetal pole, pEn = presumptive endoderm, bEc = blastoporal ectoderm, Ec = ectoderm, OrHe = oral hemisphere, AbHe = aboral hemisphere, OrEc = oral ectoderm, En = endoderm, AbEc = aboral ectoderm, PhEc = pharyngeal ectoderm, PhEn = pharyngeal endoderm, AtEn = apical tuft endoderm, AtEc = apical tuft ectoderm, At = apical tuft, M = mouth, BwEc = body wall ectoderm, BwEn = body wall endoderm, MeEc = mesentery ectoderm, MeEn = mesentery endoderm, TeB = tentacle bud, TeEc = tentacle ectoderm, TeEn = tentacle endoderm, Si = siphonoglyph, TeTi = tentacle tip, TeBa = tentacle base (The original nomenclature in [9] has been adapted to the more detailed denotations for the blastula stage in [15].)
