who is having backbone or spinal cord

Answer 2

Vertebrates are members of the phylum Chordata. Therefore, vertibrates are sometimes called chordates. All chordates contain a spinal cord. One way that scientists classify different subgroups of vertebrates is based on how organisms obtain oxygen. Vertebrates breathe either through their skin, gills, or lungs. Being endothermic or exothermic is another classifier of vertebrate subgroups. Endothermic vertebrates are warm-blooded, while exothermic vertebrates are cold-blooded. The third classifier used to subcategorize vertebrates is reproduction. Some vertebrates reproduce internally, while others reproduce externally. Some vertebrates are oviparous, which means they lay eggs. Others are viviparous, which means they give birth to live young. Vertebrate subgroups include jawless fish, cartilaginous fish, bony fish, amphibians, reptiles, birds, and mammals.
