Abstract
As is evident from every textbook of zoology, the internal skeleton or notochord of amphioxus (Branchiostoma lanceolatum) has been considered as a passive supporting organ by all but a very few investigators. Our examination, using modern techniques, however, supports the view of Ebner1 and Joseph2, who proposed a muscular nature of the notochord (Fig. 1).
