1. Kingdom Animalia

2. Kingdom Animalia Multi-celled Heterotrophic (Consumer)
Has a Nucleus (Eukaryotic)
It is the largest Kingdom so far. (See Link)
There are over 1.3 million species of Animals

3. How many of each type of Animal

4. Invertebrate Animals They do not have a backbone
Classification by structure can be done in several ways.
Body Plan (See next Slides)
Presence or Absence of a Head, Most animals have a head. But, some of the simpler animals like sponges do not have a brain or a head.
Food Digestion ( Almost all animals have a gut. A gut is a pouch lined with cells that release powerful enzymes. The enzymes break the food down into very small particles that can be absorbed by the body.

5. Invertebrate Body Plans
Radial Symmetry, Animals with radial symmetry have a body that is organized around the center like spokes on a bicycle wheel.

6. Invertebrate Body Plans
Bilateral Symmetry, Animals with this type of body plan could be split into two resulting in identical halves.

7. Invertebrate Body Plans
Asymmetrical; Animals with this body plan cannot be divided equally into two halves or be the same in any direction.

8. Invertebrate Groups (Phyla)
Porifera, Cnidaria, Platyhelminthes, Nematoda, Annelida, Mollusca, Arthropoda ,Echinodermata
Note: The animal phyla listed above are listed in order of most simple to most complex.
