What is a key difference between the subphylum urochordata and vertebrata
What is the difference between Urochordata Cephalochordata and vertebrata?
In Urochordata,the notochord, nerve cord, and postanal tail is only found in the larval stage. So they don’t have these chordate characteristics as adults. In Cephalochordata,notochord is extended in head region and shows throuhout their life. Vertebrates are obviously very different because they have vertebrae.
What is the main difference between Urochordata and Cephalochordata?
The main difference between Urochordata and Cephalochordata is the location and presence of notochord. In urochordates, the notochord is present in the larval tail, whereas, in cephalochordates, the notochord is present throughout the life and extends from the head to the tail region.
How is Subphylum Cephalochordata different from subphylum Urochordata?
The three subphyla of the phylum Chordata are Urochordata, Cephalochordata, and Vertebrata. … The main difference between Urochordata and Cephalochordata is that Urochordata consists of a notochord extended in the head region whereas Cephalochordata contains the notochord in the posterior region of the body.

Which protective brain structure do members of subphylum Vertebrata have?
Animals in Subphylum Vertebrata all have a cranium. The dorsal notochord, in most chordate embryos, develops into a spinal column (vertebrae), which protects the spinal nerves.
What does the subphylum vertebrates have that Cephalochordates do not have?
The lancelets are also called cephalochordates (Greek: kephale, “head”) because the notochord extends from near the tip of the tail to well into the anterior of the body. Because they do not have the braincase, or cranium, of a vertebrate, lancelets are often called acraniates.
What do you mean by Urochordates and Cephalochordates?
