What are the characteristics of vertebrates?

            Vertebrates are called so by virtue of their vertebrae, backbone. Therefore, the most special characteristic of vertebrate animal is this spectacular bone system. Vertebrae are the small bones forming the backbone. The vertebrae connect together by joints to form the backbone.

             The backbone not only supports the body, it also protects the spinal cord. All vertebrates have a skeleton, usually made of bones, inside their bodies. The skeleton of a vertebrate grows as the animal grows. The skeleton has three main parts- the skull, backbone and limbs.

                 Another characteristic of vertebrates is their hard skulls. These skulls protect the organs in their head. This may be the reason for the high intelligence of vertebrates. The protection of the skull helps brain development, and a result allows the enhancement of intelligence as a result.

               Most vertebrates have two pairs of limbs. In fish, the limbs take the form of fins, while others they have become legs and arms, or wings or flippers. Vertebrates like snake have no external limbs.

              Most vertebrates have stronger muscles and skeletons. These features help them to perform complex movements. All vertebrates have a fixed body structure.
