A vertebrate is an animal with a spinal cord surrounded by cartilage or bone. The word comes from vertebrae, the bones that make up the spine. Animals that are not vertebrates are called invertebrates. Vertebrates include birds, fish, amphibians, reptiles, and mammals. The parts of the vertebrate skeleton are:
Braincase: A braincase or cranium protects the brain.
Vertebrae: A series of short, stiff vertebrae are separated by joints. This internal backbone protects the spinal cord. The joints between the vertebrae let the backbone bend.
Bones: support and protect the body's soft tissues and provides points for muscle attachment.
Gill arches: Gill arches in the pharynx of fish and some amphibians support the gills. In the majority of vertebrates some of the arches have evolved into other organs, such as jaws.
Explanation:
Vertebrates comprise all species of animals within the subphylum Vertebrata. Vertebrates represent the overwhelming majority of the phylum Chordata, with currently about 69,963 species described.
