Chordata is a phylum and is broken down into three subphyla: Urochordata, Cephalochordata, and Vertebrata. Members of Urochordata and Cephalochordata live only in the ocean (Towle, 1989). Urochordate larvae have a notochord and a nerve cord but these are lost in adulthood.lso, the relationships of some chordate groups are not very well understood. 1  Phylum Chordata. 2  Subphylum Urochordata (Tunicates). 3  Subphylum Cephalochordata (Lancelets). 4  Class Myxini or Hyperotreti (hagfish). 5  Subphylum Vertebrata (Vertebrates-animals with backbones). 6  Class Conodonta (Conodonts).
