1. Animal Classification

2. VERTEBRATES (CORDATES): (1 phylum)
THE ANIMAL KINGDOM
BASIC CHARACTERISTICS OF ANIMALS: 1. 2. 3.
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.

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

7. Polyps: Sea anemones

9. Purple striped jelly, Pelagia panopyra

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

12. Planarian

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

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

24. 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

28. 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. 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
