Animalia Phyla• Deﬁnition: A group of classes with similar characteristics• Over 33 groups of phyla• Main groups are invertebrates and vertebrates
Differences Invertebrates Vertebrates- Lack backbone - Include back bone- Smaller organisms - Large organisms- No cell wall - Advanced nervous- 98% of organisms system - 2 % of organisms
Physical Characteristics• Levels of organization• Full body symmetry• Differentiation of germ layers• Formation of body cavities• Patterns of embryological development• Segmentation• Limb formation
Kingdom Members • Multicelluar- consist of one or more cells • Eukaryotic- cells contain complex structures enclosed within the membrane
To what domain does this kingdom belong? Eukaryota
Changes with evolutionary classiﬁcation • Traditional classiﬁcation was primarily based on physical similarities. Evolutionary theory was altered and now we classify organisms like this, in kingdoms.
