What are advantage of vertebrates?

While the materials may vary, muscles allow vertebrates to move around very efficiently and perform complex moves. That ability to move and the intelligence to go with it gives vertebrates such as reptiles and birds an advantage in the natural world.

Why do some vertebrates possess cartilaginous endoskeleton while others possess bony endoskeleton?

The vertebrate endoskeleton may be composed entirely of cartilage or composed of both cartilage and bone. Cartilage is less dense and therefore lighter and more flexible than bone. As a result, cartilage does not have the strength to support the large bodies of many of the higher vertebrate species.

Why is having a backbone advantageous?

The major function of the vertebral column is protection of the spinal cord; it also provides stiffening for the body and attachment for the pectoral and pelvic girdles and many muscles.

How does the skeleton of vertebrate give its body strength and support?

The internal position of bones and their central position in limbs provide firm support for small and large animals. Muscles can be inserted on all surfaces of the skeleton, in contrast to the limitations of the cuticular skeleton of arthropods, in which muscles occur on only one side.

What advantages did Jaws bring to vertebrates?

Jaws provide a powerful adaptive advantage to vertebrates because they greatly expand the range of available food sources. They also enhance the predatory ability of vertebrates, such as sharks, that are members of this early, jawed class.

What are the advantages of endoskeleton?

Flexible: The endoskeleton is jointed which allows for flexible movement and support. Muscle attachment: The muscles attach directly to the skeletal bones to allow for movement and support. Protection: The endoskeleton protects the vital organs such as the heart and lungs which are protected by the ribcage.

What is the importance of skeleton in vertebrates?

The bones of the vertebrate skull protect the brain. In the more advanced vertebrates and invertebrates, many skeletal structures provide a rigid base for the insertion of muscles as well as providing protection. The skeleton facilitates movement in a variety of ways, depending on the nature of the animal.

What are the disadvantages of a hydrostatic skeleton?

Disadvantages of a Hydrostatic Skeleton

• Structure and surface for attachment: The hydrostatic skeleton lacks a structure and does not have surfaces for the attachment of muscles or limbs.
• Lack of protection: There is very little protection for the internal organs.

What advantages do invertebrates have over vertebrates?

With the help of their specialized nerve-fiber system, they can react very quickly to changes in their surroundings, giving them a competitive edge. Compared to vertebrates (animals with backbones), most invertebrates have simple nervous systems, and they behave almost entirely by instinct.
