2 Animal Classification

3 THE ANIMAL KINGDOM BASIC CHARACTERISTICS OF ANIMALS: NINE ANIMAL PHYLA INVERTEBRATES: VERTEBRATES (CORDATES): (1 phylum) MULTICELLULAR ORGANISMS- Eukaryotic CAPABILITY OF LOCOMOTION MUST INGEST FOOD (8 PHYLA) ALL LACK INTERNAL SKELETON, SOME HAVE EXOSKELTON OR SHELL INTERNAL SKELTON MADE OF BONE/ CARTILAGE.

4 1. Phylum PORIFERA: ‘Pore- Bearing” Filter feeders Asymmetrical Feed and get rid of wastes thru diffusion Sessile=nonmotile, attached to a surface while living Ex.- sponges

5

6 2. Phylum CNIDARIA EXAMPLES: CORAL, JELLYFISH, SEA ANEMONE Have stinging tenacles Stun prey with toxins Prey is drawn into mouth and dissolved/ digested Radial symmetry

7

8 Polyps: Sea anemones

9

10 Purple striped jelly, Pelagia panopyra

11

12 3. Phylum PLATYHELMINTHES: EXAMPLES: PLANARIA, FLUKE, TAPEWORM Flat worms One opening for ingestion and elimination Primitive nervous system Exchange gases by diffusion thru moist membranes Bilateral symmetry

13 Planarian

14

15

16 4. Phylum ANNELIDA EXAMPLES: LEECH, EARTHWORMS Segmented worms Each segment has a nervous. circulatory, excretory, muscular system Bilateral symmetry First organism with complex body systems

17

18

19 5. Phylum Nematoda Round worms Have long, slender bodies Have a hollow, fluid filled body cavity Most are free-living on land or in fresh or salt water Many species are parasitic Examples- Ascaris, hookworms, pinworms

20

21 6. Phylum ARTHROPODA EXAMPLES: SHRIMP, LOBSTER, CRAB, BARNACLE Animals with jointed appendages Have an exoskeleton They shed their exoskeleton (molt) We study crustaceans – these are marine arthropods

22

23

24

25 7. Phylum MOLLUSCA All have a soft body There are 3 classes: gastropods, bi-valves, cephalopods Most have an external shell. Have bi-lateral symmetry Cephalopods are extremely intelligent ex.- snail, clams, squid, octopus, cuttlefish, nautilus

26

27

28

29 8. Phylum ECHINODERMATA Have spiny bodies Radial symmetry Benthic- bottom dwellers Central mouth on ventral surface ex.- sea urchin, sea star, sea cucumber, sand dollar

30

31 9. Phylum CHORDATA Have a backbone that protects the spinal cord=ALL vertebrates!!! Most developed nervous system Contains animals that we are most familiar with ex.- fish, mammals, reptiles, amphibians, birds
