Are vertebrates the largest group among the chordates?
Vertebrates are a subgroup of the chordates, meaning that all vertebrates are chordates, but not all chordates are vertebrates. Vertebrates are distinguished from other chordates by having backbones or spinal columns.All vertebrates have muscular systems that mostly consist of paired masses, as well as a central nervous system which is partly located inside the backbone (if one is present). The defining characteristic of a vertebrate is considered the backbone or spinal cord, a brain case, and an internal skeleton, but the latter is not true for lampreys, and the former is arguably present in some other chordates. Rather, all vertebrates are most easily distinguished from all other chordates by having a clearly identifiable head. Sensory organs--especially eyes--are concentrated at the foreend of the body, and there is pronounced cephalization.

What is the feature not unique to vertebrates.?
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.
