Objectives Describe characteristics common to animals Describe the characteristics of 6 major animal phyla Identify on sight members of 6 major animal phyla Define invertebrate, chordate, vertebrate

6 characteristics of animals Multicellular Heterotrophs Mostly sexual reproduction No cell wall Motile at some stage Complex organ structures to respond to environment quickly
