The document summarizes the animal kingdom by describing the major categories of vertebrates and invertebrates. It notes that there are approximately 2 million known living things, including animals which move and can be divided into vertebrates and invertebrates. It provides details on common vertebrate groups like mammals, fish, birds, amphibians and reptiles, and invertebrate groups including crustaceans, mollusks, annelids and insects.

9.  Reptiles are cold blooded animals so
they can change their body temp.

collection of groups from single celled
protozoa to highly specialized insect and
spider.
