Domain Eukaryota
Kingdom Animalia
Animal Characteristics:
Multicellular, Heterotrophic, Eukaryotic, no cell walls, typically
reproduce sexually, capable of motion at some stage in their life.
We will survey the Kindom Animalia by looking at the 9 major phyla
from the simplest animal phylum to the most complex animal phylum.

SYMMETRY
Symmetry-- Body Plan. How body parts are arranged. The balanced
distribution of duplicate body parts or shapes.
3 types of symmetry are seen in animals.
1)
Asymmetry--No Body Plan
Ex. Sponges
2)
Radial Symmetry- Body parts arranged around a center point.
--Any cut through central point results in identical halves.
--No head, front, back.
--Oral surface and an Aboral surface.
Ex. Sea Anemone, Jellyfish, Starfish, Sea Urchin
3)
Bilateral Symmetry- Arrangement of body parts along a central line or plane.
--Only one way to cut to get mirror image halves.
--Use terms like: anterior, posterior, dorsal, ventral
Ex. Worms, lobster, whale, clams, human, squid
All bilaterally symmetric organisms have a dorsal, ventral, anterior, and
posterior region.
