VertebratesVertebrates

VertebratesVertebrates are animals that have a are animals that have a backbone. The backbone consists of backbone. The backbone consists of ring-like bones (vertebrae) that protect ring-like bones (vertebrae) that protect the soft spinal cord. Vertebrates can be the soft spinal cord. Vertebrates can be warm-blooded, like humans, or cold-warm-blooded, like humans, or cold-blooded, like fish. Vertebrates include blooded, like fish. Vertebrates include amphibians, fish, reptiles, birds, and amphibians, fish, reptiles, birds, and mammals.mammals.
