Cordata Taxonomy

Cordata Taxonomy From Wikipedia (exitinct branches of the taxonomy suppressed), some information from links to the link above:

Phylum Chordata

-Subphylum Urochordata - Tunicates (tadpole like in youth, adults are fixed to a single location)
--Class Ascidiacea (Aplousobranchia, Phlebobranchia, and Stolidobranchia),
--Class Thaliacea,
--Class Appendicularia (Larvacea)
--Class Sorberacea.
[Newer evidence indicates that the Ascidiacea is an artificial group. The new classification would then look like this.]
-- Class Stolidobranchia,
-- Class Phlebobranchia and Thaliacea,
-- Class Aplousobranchia and Appendicularia,
-- Class Sorberacea would belong somewhere in Ascidiacea, or be in a taxon on its own
