In addition, the gene expression is evident in the ectodermal cells of the stomodium, and this pattern is retained in the 3-day-old tornaria larva. The stomochord, which was once thought to be homologous to chordate notochord (18), is formed in the basal region of the proboscis during metamorphosis.
