In phylum Chordata there are 4 sub phylums. 1.Vertebrata 2.Hemichordata 3.Urochordata 4.Cephalochordata Vertebrata consist of 6 classes. 1.Chondrichthyes 2.Osteichthyes 3.Amphibia 4.Reptilia 5.Aves 6.Mammalia
Protochordata is a subphylum within the phylum Chordata. It includes three groups: Hemichordata, Urochordata (Tunicata), and Cephalochordata. These organisms exhibit some characteristics of chordates, such as a notochord and dorsal hollow nerve cord, but lack some of the defining features found in more advanced chordates like vertebrates.
No, hemichordata and protochordata are not the same. Hemichordata is a phylum of marine deuterostome animals, while Protochordata is a subphylum of chordates that includes organisms like tunicates and lancelets. Both groups are primitive chordates but belong to different taxonomic classifications.
The sea squirt is in the phylum Chordata.
