Please only submit sites to do with the Cephalochordata here.Cephalochordates are non-vertebrate members of the Phylum Chordata, having diverged from the evolutionary line leading to the vertebrates before the end of the Precambrian. A cephalochordate has no head, a transparent body like a leaf with a notochord running from end to end, and rows of muscle on either side by which to wriggle, swim or bury itself. They are commonly known as lancelets.

Please only submit sites to do with the Urochordata.The subphylum Urochordata, is also sometimes known as the Tunicata. These animals are commonly known as tunicates or sea squirts. Some pelagic tunicates are known as salps. There are two classes recognized within the subphylum: Thaliacea and Ascidiacea. The body of an adult tunicate is quite simple. Essentially it is a sack with two siphons through which water enters and exits. Many tunicates have a larva that is free-swimming and exhibits all chordate characteristics, including a notochord. In many tunicates this "tadpole larva" eventually attaches to a hard surface and loses its tail, the ability to move, and most of its nervous system. The tunicate group knows as salps are entirely free-swimming, however.
