Objectives
1. You should know the characteristics shared by all organisms in the Kingdom
Animalia.
2. You should be familiar with the major differences, trends, and changes in
body plans between the animal phyla; symmetry, level of cellular or tissue
organization, coelome formation, mesoderm development, and segmentation.
3. You should be familiar with the origin of animal life including the time of
development, hypotheses regarding the origin of such life, and the underlying
genetic pattern that unify such life.
4. You should be familiar with the relationship of the Kingdom Animalia with the
other four phyla.
5. You should be familiar with the protozoan organisms, their many forms of
locomotion, and various other general characteristics.
6. You should be familiar with the scientific and common names of the animal
phyla covered in class, as well as the general and defining characteristics of
each.
7. You should be able to compare and contrast the methods of movement and
feeding/digestion in each of the animal phyla cover in class.
8. You should be familiar with various other general characteristics for some of
the animal phyla covered in class including respiration, reproduction,
excretion, sensation, nervous systems, and circulation.
9. You should understand the relationship between surface area and volume,
and how this relates to the size and shape of various animal phyla.
10. You should be familiar with the continuum from colonial to multicellular
organism and how the anatomy and physiology of the Portuguese Man-ofWar exemplifies the dichotomy existing in this continuum.
