or not is one of the important structures of animals, but not all animals have vertebrae. Those with vertebrae are called vertebrates, while those without vertebrae are called invertebrates. This is a general term for two groups of animals, each of which contains many species. The difference between the two is very big.
In terms of classification, lizards belong to the subphylum Vertebrata of the phylum Chordata, which is a group of animals with vertebrae. The spine of lizards, like that of other animals, plays an important supporting role, located in the center of their bodies, supporting their bodies, so that they can complete a variety of complex life activities. If there is no spine, lizards can not move normally, let alone complete more complex life activities, so there is no way to survive.
? As mentioned above, lizards belong to the subphylum Vertebrata of the phylum Chordata, so they are vertebrates, and they also have vertebrae in their bodies. Compared with invertebrates, vertebrates are more advanced animals. The same is true of lizards, which are more advanced than invertebrates and have more complex body structures. Vertebrates are also divided into many subcategories. Specifically, lizards belong to reptiles among vertebrates. In addition to reptiles, vertebrates also include many other species, such as fish, mammals, birds, amphibians and so on, and there are many differences between these subclasses.
