Since there are a large number of different organisms exist on earth, they can be classified into smaller groups, and this makes easier to study and remember the organisms. Metazoans can be further divided into two major subgroups; (1) Invertebrates; those who lack backbone and internal skeleton such as earthworms, insects, snails etc., and (2) vertebrates, which include animals with backbone and internal skeleton such as amphibians, reptiles, birds and mammals. Metazoans are a monophyletic group, i.e. they have a common great grand ancestor. This signifiies that eumetazoa have more complexly organized tissue than parazoa do.
