Kingdom animalia

1. Kingdom A nimalia

2. C haracteristics They are heterotrophic. All are multicellular . They all vary in size. 2 classifications - Invertebrates: without backbone - Vertebrates: with backbone Composed of 9 phyla

3. I nvertebrates Porifera Cnidaria Platyhelminthes Nematoda Annelida Mollusca Arthropoda Echinodermata Vertebrates Chordata

4. Phylum Porifera Also known as SPONGES Have PORES or HOLES in their bodies and a single large opening called osculum Filter feeders Has two layers of cells -epidermal cells -collar cells

5. Phylum Cnidaria Hollow, tube-like bodies Presence of nematocyst Bodies are composed of two layers of tissue: epidermis and gastrodermis Food is ingested and expelled through the gastrovascular cavity

6. Sea Anemone

7. Hydra

8. Phylum Platyhelminthes Commonly known as flatworms Flat bodies They posses only a hollow sac with a single opening for food and waste excretion

9. Liverfluke

10. Marine Worm

11. Phylum Nematoda Commonly known as roundworms Round bodies covered with cuticle Ascaris and hookworms are examples

12. Phylum Annelida Characterized by ring like body parts Have similar segments throughout their bodies Presence of mouth and anus Have hearts and blood vessels

13. Phylum Mollusca Have soft bodies but they have hard protective shells as outer body covering Mussels, clams, and oysters are examples

14. Phylum Arthropoda Most diverse of all the phyla Exhibits cephalization Well developed nervous system (brain and nerve cord) Have segmented bodies Body is divided into 3 segments (head, thorax and abdomen) Exoskeleton is made up of chitin They molt or shed their exoskeleton as they grow up

15. Phylum Echinodermata Has a tube feet system of canals For sucking in seawater to obtain nutrients and for expelling wastes.

16. Phylum Chordata Three distinguishing structures: -notochord -skull -vertebral column or backbone

17. Major classes of Vertebrates Agnatha (jawless fishes) Chondrichthyes (cartilaginous fishes) Osteichthyes (bony fishes) Amphibia Reptilia Aves Mammalia

18. Class Agnatha Jawless fishes but have sucking mouth parts No paired fins, jaws or scales Notochord serves as the skeleton of agnathans

19. Class Chondricthyes Skeletons are made up of cartilage Have gills, fins and scales Have toothlike scales

20. Class Osteichthyes Called bony fishes Skeletons are made up of bones Scales are flattened Presence of swim bladder

21. Class Amphibia They generally live in or near bodies of water Early stages on water, adult stage on land

22. Class Reptilia Have hard body coverings (scales or plates) Sharp claws on their toes adapted for climbing and tearing prey Cold-blooded organisms They breathe through their lungs Most are egg laying

23. Class Aves Feathers cover the bodies of birds Presence of beak or bill for food getting A pair of wings that enables them to fly Warm-blooded animals All of them are egg-laying

24. Class Mammalia Presence of mammary glands These secretes milk (in females) Warm blooded animals They reproduce through sexual means
