The document summarizes the key characteristics and classifications of the Animal Kingdom. It discusses that animals are multicellular, obtain food from outside sources, and move to get food. It then classifies animals into two main groups - invertebrates without backbones and vertebrates with backbones. Finally, it outlines the 9 main phyla that make up the Animal Kingdom - including sponges, jellyfish, worms, mollusks, echinoderms, arthropods, and chordates.

1. The Animal Kingdom
GENERAL CHARACTERISTICS:
 Most complex of all kingdoms
 Multicellular (made of many cells)
 They obtain food from OUTSIDE SOURCES
 They move from place to place to get food
 They swallow their food and they digest food
inside the body.

2. The Animal Kingdom-
REVIEW
1)INVERTEBRATE- An animal that does not
have a backbone
2) VERTEBRATE- An animal that has a
backbone

4. The Animal Kingdom Cont’d
Porifera:
Means “having pores”
Ex: sponges

5. The Animal Kingdom
Coelentrata:
Sac-like body
Have tentacles
Ex: hydras, jelly fish, coral, sea anemones

6. 3 Phyla of Worms:
Flatworms
Roundworms
Segmented worms

7. Molluska:
Hard shell surrounding soft body parts
Live in water & damp places
Examples:

8. Echinoderms:
Means “spiny-skin”
Star shaped
Spiny
Ex:
Starfish & Sea Urchin

9. Arthropoda:
Makes up 75% of the animal kingdom
Basic Characteristics:
hard external skeleton

jointed legs
Ex: beetle, milli & centipede, spider, crab

10. Chordata:
Vertebrates
Have internal skeleton
