One feature not unique to vertebrates is the presence of a notochord, which is a flexible rod-like structure that provides support. While vertebrates have a more complex backbone and nervous system, notochords are also found in other animal groups, such as cephalochordates and some invertebrates, indicating a more primitive form of structural support. This evolutionary trait highlights the shared ancestry among different animal phyla.
"Vertebrata" more accurately describes the morphological characteristic of the group, as it refers to the presence of vertebral column or backbone, which is a defining feature of vertebrates. "Craniata" focuses solely on the presence of a skull, which is not unique to vertebrates.
