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. As with all chordates—a group that includes tunicates (subphylum Urochordata),hagfish (class Agnatha), and all vertebrates (class Vertebrata)—cephalochordates have a notochord Amphioxus, also known as lancelet, are small marine animals that are members of invertebrate subphylum Cephalochordata of the phylum Chordata. This plate can be found in Ernst Haeckel's Natürliche Schöpfungsgeschichte: Gemeinverständliche Wissenschaftliche Vorträge über die Entwickelungslehre , or The History of Creation: Or the Development of the Earth and Its Inhabitants by … Amphioxus was first discovered in Europe as a lancelet. Taxonomically, it belongs to the subphylum Cephalochordata, which means “chordate in the head.” The fossil evidence, as well as the modern molecular phylogenetic tree, suggests amphioxus as the most basal chordate. 2016-12-10 2019-03-28 The lancelets (/ˈlænslɪts/ or /ˈlɑːnslɪts/), also known as amphioxi (singular: amphioxus /æmfiˈɒksəs/), consist of some 30–35 species of fish-like benthic filter feeding chordates in the order Amphioxiformes. They are the modern representatives of the subphylum Cephalochordata. Lancelets closely res The main taxa within Phylum Chordata include: Subphylum Cephalochordata ( cephalo = head), which doesn’t have a “head.” This subphylum includes lancelets (or Subphylum Urochordata ( uro = tail) are called the tunicates.

Amphioxus is a member of the cephalochordate subphylum that represents the most basally divergent lineage of chordates. It shows all the prototypic  Amphioxus are the earliest diverging chordate subphylum, and thus are the sister group to the urochordates (tunicates) plus vertebrates.

(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.

Amphioxus is still used, however, as a convenient common name for all of the approximately 25 species in this diminutive subphylum.

Subphylum Cephalochordata (Canadian Campbell 2nd ed. Page 761, Fig 34.4)In this subphylum the similarity of Amphioxus to the vertebrates is most obvious.Amphioxus is a small, translucent animal, fishlike in appearance and proportions, found in shallow marine waters in various regions of the world. As its shape suggests, it can swim readily, but spends most of its time with its body buried in

Amphioxi are small marine animals found widely in the coastal waters of the warmer parts of the world and less commonly in temperate waters.

Other genera as Epigonichthys is now synonym with Asymmetron and Amphioxides, once considered as member of the family Amphioxididae, now considered as giant larval individuals of the genus Asymmetron.
