How are cartilage and bone similar?
Both substances hold together the bodies of various creatures such as mammals, fish and other vertebrates. Cartilage (also known as gristle particularly in the context of cooking) is firm, flexible elastic tissue; in vertebrates - at least, the higher orders - the unborn or very young have a lot of cartilage which is mostly replaced by bone as the subject matures, though ears, for example, stay as cartilage. Cartilaginous creatures such as sharks never develop bones and their skeletons are completely cartilaginous, though their teeth are of course formed with calcium. Bones are rigid connective tissue (which is why they're no good for ears, for example) formed mostly of calcium phosphate and collagen and, unlike cartilage, are rigid individually and flexible only where joints are available, such as knees, elbows, jaws and so on.
