‘Deuterostomes I: starfish, sea squirts, and amphioxus’ is concerned with some of the phyla of the Deuterostomia superphylum — the Echinodermata, Hemichordata, and the Chordata subphyla tunicates and amphioxus. The five classes of echinoderms — starfish, sea urchins, brittlestars, sea cucumbers, and sea lilies — have much in common with each other, but little with anything else. They

It measures about 5-7 compound in length, the colour of the body is dark red and reddish brown. The body of the amphioxus is divided into two parts: The trunk and tail. The head is absent. The phylogenetic position of amphioxus, together with its relatively simple and evolutionarily conserved morphology and genome structure, has led to its use as a model for studies of vertebrate evolution. In particular, the recent development of technical approaches, as well as access to the complete amphioxus genome sequence, has provided the community The genome of amphioxus includes AmphiNk2-2, the first gene of the NK2 homeobox class to be demonstrated in any invertebrate deuterostome.
