THE ANIMAL KINGDOM

Characteristics of ALL Animals… • Multi-cellular • Eukaryotic (nucleus) • Consumers • Mobility

PART 1: Simple Animals 1. SPONGES: • Most simple of all animals • Feed, breathe, and eliminate waste through pores • Traps what it needs as water flows thru • Sexual and asexual reproduction

2. STINGING-CELL ANIMALS • • Animals have stinging tentacles Sexual reproduction Have “mouth” structure Radial symmetry Anemone Hydra Jellyfish

3. Flatworm • Flat in shape • Bilateral symmetry • Cephalization – “head” structure • Example: a. Tapeworm – Parasitic – Intestines – Can be very long b. Planaria – non-parasitic – found in freshwater – mouth/anus same structure

4. Roundworm • • Round in shape Separate mouth and anus Bilateral symmetry Example: – Ascaris • Parasitic roundworm • Causes death in 3 rd world countries

5. Segmented Worms • Body divided into “segments” • Live anywhere (land, fresh + salt water) • Examples: Earthworm Leech

• • 6. Soft-Bodied Animals (a. k. a. Mollusks) Soft body Usually protected with a hard shell Muscular foot for movement Examples: clam, oyster, scallop, slug, snail octopus
