At some point in their development, all vertebrates possess many common features.
What are vertbrates?
An animal with a spinal cord encased in bone or cartilage is referred to as a vertebrate. The word is derived from vertebrae, the spine's bony structure.
The vertebrate skeleton is composed of:
- A braincase, also known as a cranium, shields the brain. Short, rigid vertebrae that are connected by joints make up the vertebral column. The spinal cord is safeguarded by its internal backbone.
- The backbone may flex thanks to the joints between the vertebrae.
- The body's soft tissues are supported and protected by bones, which also act as sites of attachment for muscles.
- Gill arches: The gills are supported by gill arches in the throat of fish and some amphibians. Most animals have arches, some of which have developed into other structures like jaws.
