They are the modern representatives of the subphylum Cephalochordata.

Four species of amphioxus are found in North American coastal waters. 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, homeodomain, and NK2-specific domain; on the basis of amino acid identities in these conserved regions, AmphiNk2-2 is a homolog of Drosophila vnd and vertebrate Nkx2–2. Lancelets (amphioxus) of the chordate subphylum Cephalochordata in the phylum Chordata are found in tropical and temperate oceans worldwide.

2008-06-19 The lancet, also called amphioxus, is a free-swimming marine organism that bears a striking resemblance to the the ammocetes larva of the lamprey. Generally the lancet lives tucked into the sediment exposing only its mouth (Figure 1), which takes in water to filter through their pharyngial gillslits amphioxus Phylum Chordata, Subphylum Cephalochordata. Any of the genusBranchiostoma, a little, fish-like, simple chordate, that lives partially buried in marine sand flats and is also known as a lancelet.

This Cephalochordata (or lancelets, traditionally known as amphioxus, plural amphioxi) is a subphylum of marine invertebrates of the phylum Chordata.They are usually found in shallow parts of temperate or tropical seas.

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.
