DENDROLOGY

Detailed explanation-1: -Vertebrates are differentiated by having a vertebral column. As chordates, all vertebrates have a similar anatomy and morphology with the same qualifying characteristics: a notochord, a dorsal hollow nerve cord, pharyngeal slits, and a post-anal tail.

Detailed explanation-2: -An animal that has a backbone and skeletal system is called a vertebrate. Vertebrates are animals with backbones and skeletal systems. A backbone can also be called a spine, spinal column, or vertebral column. The individual bones that make up a backbone are called vertebrae.

Detailed explanation-3: -Bones are rigid organs that form part of the endoskeleton of vertebrates. They provide structural support for the body, assist in movement by opposing muscular contraction, and create a protective wall around internal organs.
