Science Main Index. Animals with an internal skeleton made of bone are called vertebrates. Vertebrates include fish, amphibians, reptiles, birds, mammals, primates, rodents and marsupials. Although vertebrates represent only a very small percentage of all animals, their size and mobility often allow them to dominate their environment.
Bones are rigid organs that form part of the endoskeleton of vertebrates. They function to move, support, and protect the various organs of the body, produce red and white blood cells and store minerals.Bone tissue is a type of dense connective tissue. Bones have a complex internal and external structure making them lightweight, yet strong and hard.One of the types of tissue that makes up bone is mineralized osseous tissue. This tissue gives bone rigidity and a honeycomb-like three-dimensional internal structure.Other types of tissue found in bones include marrow, endosteum, periosteum, nerves, blood vessels and cartilage.The skeleton is an animalâs internal support frame.ther animals possess a skeleton on the outside of their body called an exoskeleton.
