List the characteristics of vertabrates

Answer 1

One characteristic of the subphylum are that all members 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 do not hold 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, that is, sensory organs - especially eyes are concentrated at the fore end of the body and there is pronounced cephalization. Compare the lancelets which have a mouth but not a well-developed head, and have light-sensitive areas along their entire back

Answer 2

Vertebrates are animals with a backbone or spinal column, which gives them structure and support. They have a well-developed nervous system with a brain encased in a skull, as well as a bilateral symmetry and a complex internal organ system. Vertebrates also typically have paired appendages such as arms or legs.
