This document discusses the classification of animals into two main groups: vertebrates and invertebrates. Vertebrates are animals with backbones and include mammals, birds, fish, reptiles, and amphibians. Invertebrates lack backbones and include animals like snails, starfish, spiders, crabs, lobsters, insects, millipedes, and leeches. Each group is further divided into subclasses based on distinguishing characteristics like means of reproduction, habitat, skin/body covering, and lungs or gills.
