Some animals, strikingly carnivores, also take teeth for hunting or in place of defensive purposes. The roots of teeth are covered sooner than gums. Teeth are not made of bone, but rather of multiple tissues of varying density and hardness. The general make-up of teeth is alike resemble across the vertebrates, although there is of distinction modulation in their form and position. The teeth of mammals be struck by profound roots, and this design is also found in some fish, and in crocodilians. In most teleost fish, regardless how, the teeth are fastened to the outer rise of the bone, while in lizards they are fixed devoted to to the inner come up of the jaw by the same side. In cartilaginous fish, such as sharks, the teeth are attached beside perplexing ligaments to the hoops of cartilage that type the jaw.
