1. Kingdom-Animals

2. Animal Characteristics Heterotrophs Multicellular No cell walls Tissues (most) Sexual Reproduction (most)

3. Remember classification Kingdom- Animals Phylum – OUR FOCUS Class Order Family Genus species

4. Phylum Porifera- sponges

5. * no symmetry, no tissues/organs *evol- multicellular

6. Cnidaria Jellyfish-medusa Coral- Many polyps living together Radial symmetry Evol- Tissues

7. www.mennoniteusa.org/ news/news/02_25_04.htm Platyhelmithes(Flatworm ) Evol- Bilateral

8. Nematoda Guinea Worm (round worm) Nematode Worms (round worms) Evol- Pseudocoelom (mouth and anus)

9. Mollusca Evol- True ceolom (organs) –Visceral Mass: central part with organs –Mantle: Outer body layer –Foot: Movement

10. Earthworms and Leeches! (Phylum- Annelids) Evol- Segmentation

11. Arthropoda Evol- Jointed appendages The Classes –Arachnids, Insects, Crustaceans

12. Echinodermata Evol- Deuterstome Development –(In other words they develop the same way vertebrates do) –Also have an endoskeleton

13. Vertebrates (Agnatha) Jawless, cartilaginous bodies, ectotherm Lampreys

14. Vertebrates Chondrichthyes Sharks Cartilaginous skeleton, gills, jaws, 2 chambered heart, internal reproduction, ectotherm

15. Vertebrates (Osteichtyes) Bones, 2 chambered heart, gills, external reproduction, ectotherm

16. Vertebrates (Amphibians) Gills + Lungs, 3 Chambered heart, external reproduction, ectotherm

17. Vertebrates (Reptiles) Lungs, Internal reproduction shelled egg, 3 chambered heart, ectotherm Exception to rule Crocs have a 4 chambered heart (more closely related birds)

18. Vertebrates (Aves) Lungs, Internal reproduction shelled egg, endotherm, 4 chambered heart

19. Vertebrates (Mammals) Internal development, lungs, 4 chambered heart, endotherm
