1. KINGDOM ANIMALIA

2. CARLOS LINNAEUS First to classify animals He only named 4,236 The first edition of Systema Naturae was printed in the Netherlands in 1735 Today more than a million!

3. MAKE A LIST OF CHARACTERISTICS THAT BELONG TO THE ANIMAL KINGDOM Eukaryotic Heterotrophs Multicellular Specialized cells Sense organs No cell wall

4. ANIMAL FEATURES Diploidy 2 copies of each chromosome Leads to genetic diversity

5. BLASTULA FORMATION (EXCEPT SPONGES) Zygote undergoes cell division and forms a ball of cells which produces primary tissue layers

6. TISSUE A group of cells that perform a common function Specialization Ex: Muslce, adipose

7. MULTICELLULARITY Which is related to an animal’s body plan Types of symmetry: Asymmetry : irregular ex: sponges Radial Symmetry : parts arranged in a celentral axis Bilateral symmetry District R and L halves Dorsal/ventral Anterior/Posterior Cephalization

9. HETEROTROPHY Filter feeders or ferocious predators

10. NO CELL WALL

11. SEXUAL REPRODUCTION External Lg amount of gametes are produced, but…What are the benefits? Internal Within females body What are the benefits?

12. TYPES OF TISSUES 1.Epithelial 2.Neural 3.Connective 4.Muscle Cardiac Smooth Skeletal

16. Cardiac Tissue Skeletal muscle Tissue Smooth muscle Tissue

17. PHYLUM PORIFERA “PORE BEARERS ”

18. Symmetry Asymetrical Reproduction Asexual: budding/fragmentation Sexual: hermaphrodites Evolutionary Milestone multicellularity Circulatory System Diffusion Unique Characteristic sessile regeneration Importance Food chain Absorbent qualities

19. CNIDARIA “ STINGING CREATURES ”

23. Symmetry Radial Reproduction Asexual: budding Sexual: hermaphrodites Evolutionary Milestone Tissues (no organs) Circulatory System Diffusion Gastrovascular cavity Unique Characteristic Stinging cells: cnidocytes Tentacles Importance Edible Protect shorelines Habitat for others

24. COELOM: BODY CAVITY FLUID FILLED SPACE IN MULTICELLULAR ANIMALS Coelomate animals: true cavity: with a complete lining called peritoneum derived from mesoderm Pseudocoelomate animals have a pseudocoel: “false cavity” tissue derived from mesoderm only partly lines the fluid filled body cavity of these animals. All pseudocoelomates are protosomes Acoelomate animals, like flatworms, have no body cavity at all. Organs have direct contact with the epithelium.

26. PLATYHELMINTHES “FLAT WORMS”

27. Symmetry Bilateral Reproduction Asexual Sexual: some are hermaphrodites Evolutionary Milestone Cephalization: bilateral symmetry Circulatory System Diffusion Unique Characteristic No body cavity (acoelms) Cephalization: (no animals before group had head) Importance Cause diseases (if wade in water larvae bore thru skin to blood vessels)

28. NEMATODA “ROUND WORMS ”

30. Symmetry Bilateral Reproduction Sexual Evolutionary Milestone Body cavity Pseudocoelm: provides space for development of organs Circulatory System Open: fluids circulate within body cavity Unique Characteristic Tube within a tube Importance Cause diseases parasitic

31. CIRCULATORY SYSTEM

32. MOLLUSCA “The Mollosks”

34. Symmetry Bilateral Reproduction Most are distintive male and female Snails: hermaphrodites Evolutionary Milestone Coelm: true body cavity Circulatory System Open: 3 chambered hearts Closed: octopus and squid Unique Characteristic True coelm Only phyla (group) of coelmates that is not segmented Radula Importance Food chain: edible pearls

35. TOOTHLIKE SCRAPING DEVICE

36. ANNELIDA “SEGMENTED WORMS”

37. Symmetry Bilateral Reproduction Hermaphrodites Evolutionary Milestone Segmentation Circulatory System Closed Unique Characteristic Ganglion: primitive brain Organ systems clitellum Importance Medicinal purposes Fertilize soil and creates air spaces

38. Arthropoda “BUGS”

39. 3 CLASSES OF ARTHROPODS 1.Crustaceans 2.Arachnids 3.Insects

40. Symmetry Bilateral Reproduction Parthenogenesis Metamorphosis Evolutionary Milestone Jointed appendages Circulatory System Closed Unique Characteristic Jointed appendages Exoskeleton Wings Compound eyes Importance Food Causes disease or transmits Food chain: pollinators!

41. Echinodermata “spiny skinned”

42. Symmetry Larvae: bilateral Adults: radial Reproduction Sex: gonads Evolutionary Milestone Deuterostome (Pattern of embryonic dev. Where anus forms @ the blastopore) Circulatory System Closed Unique Characteristic Endoskeleton Tube feeders No head or brain Regenerate “arms” Importance Food chain
