Urochordata Notochord is present in the tail of larva.
Three phyla—Urochordata (Tunicata), Cephalochordata, and Vertebrata—make up the phylum Chordata. The existence of a notochord, a cartilaginous rod supporting the body in chordates in either adult stages or in animal stages, has been discovered in all three of these classes of creatures.
Animals called cephalochordates have long, segmented bodies with a notochord that runs the length of the body from head to tail.
On the other hand, Vertebrata includes all animals that fall under the subphylum Vertebrata. They can be identified by the vertebrae—the spine's individual bones—that they have.
On the other hand, urochordata are known as tunicates because a tunic encircles their bodies. They are made up of the adult and larval stages. They have a notochord in their tail while they are larvae, but it is absent when they are adults.
