The genome of amphioxus includes AmphiNk2-2, the first gene of the NK2 homeobox class to be demonstrated in any invertebrate deuterostome. AmphiNk2-2 encodes a protein with a TN domain, Amphioxus belongs to the Cephalochordata because amphioxus has nerve cord and other morphological structures the same as Cephalochordata. (ii) Balanoglossus belong to Hemichordates subphylum of phylum Chordata. Balanoglossus belong to hemichordates because balanoglossus body divided into 3 regions: Proboscis, collar, The amphioxus has many such epithelial sensory cells including type I cells of Lacalli (Lacalli and Hou, 1999). But secondary sensory neurons first make a substantial appearance in this group of organisms. The epithelial secondary sensory cells of Amphioxus (type II receptors; Holland and Yu, 2002) extend immotile cilia to the epithelial surface.
