Kingdom Animalia

1. Kingdom Animalia Unit 2 - Biodiversity

2. Hierarchy-Taxonomic Groups • Domain • Kingdom • Phylum (Division – used for plants) • Class • Order • Family • Genus • Species BROADEST TAXON

3. How are the Kingdoms Organized? • Type of cells- • prokaryotic/eukaryotic • # of Cells - unicellular/multicellular • Feeding - autotrophic/heterotrophic • Cell Structure- • No cell wall

4. What is a Prokaryotic Cell What is a Eukaryotic Cell No Nucleus Nucleus

5. What is Unicellular? What is Multicellular? One cell More than one cell

6. What is a Heterotroph? What is an Autotroph? Make their own food Do NOT make their own food

7. K. Animalia Characteristics • Multicellular – many cells • Heterotrophic – consume other organisms for energy • Eukaryotic – Have a nucleus • Lack cell walls – have NO cell walls

8. Animal Organization • K. Animalia is divided into 9 phyla based on: • Level of organization • (cellular, tissue, organ system etc.) • Body symmetry • (asymmetry, radial, or bilateral) • Cephalization • (concentration of sensory tissue at the head) • Body cavity formation • We will concentrate on: • Level of Organization • Cellular, tissue, organ … • Body Symmetry • Radial vs bilateral vsassymetrical • Mode of Reproduction • Sexual vs. Asexual • Energy Source • Endothermic vsEctothermic

9. 9 Phyla of the Animal Kingdom VERTABRATES INVERTABRATES • CHORDATES • Fish • Amphibians • Reptiles • Birds • Mammals • SPONGES • CNIDARIANS • FLATWORMS • ROUNDWORMS • MOLLUSKS • ANNELIDS • ARTHROPODS • ECHINODERMS

10. 2 main groups Invertebrates Vertebrates • No spinal column • Spinal column

11. Vertebrates Animals with a spinal cord and an endoskeleton.

12. Fish • Aquatic, have fins, scales and gills. • Herbivores, carnivores, parasites and filter feeders. • Sexual – eggs fertilized internally or externally • Bilateral body symmetry • Ectothermic or cold blooded • Found in water

13. Amphibians • Their skin is usually smooth and lacks scales, hair, and feathers. Their skin must remain moist to aid in breathing. They lack claws on their toes. • Herbivores as youth and carnivorous as adults. • Sexual reproduction – eggs fertilized internally or externally • Bilateral body symmetry • Ectothermic or cold blooded • In water as larva and on land as adults.

14. Reptiles • Their skin has scales and is dry. They have claws on their toes, teeth and lay eggs on land. • Herbivores and carnivores • Sexual Reproduction – eggs fertilized internally. • Bilateral • Ectothermic or cold blooded • Found in Temperate Climates

15. Birds • Their skin is covered with feathers. They have four-chambered hearts. Their bones are lightweight and usually hollow. Their forelimbs are modified as wings. They lay eggs. • Herbivores and carnivores • Sexual reproduction – eggs fertilized internally. • Bilateral Symmetry • Endothermic or warm blooded • Found everywhere.

16. Mammals • They have hair, which varies greatly among species. Most have sweat glands. They have mammary (milk-secreting) glands to feed their young. • Herbivores and carnivores • Sexual Reproduction –fertilized internally. • Bilateral body symmetry • Endothermic or warm blooded • Found almost everywhere

17. Invertebrates No spinal column Some with exoskeletons

18. Porifera (poh-RIF-ur-uh) • Sedentary. Body is made of cells and tissues surround by a water filled space but there is no true body cavity. • filter feeders • Sexual & asexual (budding) • Asymmetrical body symmetry • Ectothermic or cold blooded • Live in aquatic environments, mostly marine.

19. Cnidaria (ny-Dayr-ee-uh) • Are all radial in symmetry, have stinging tentacles to catch prey. • carnivorous and filter feeders • Sexual & asexual (budding) reproduction • Radial Symmetry • Ectothermic or cold blooded • Marine and fresh water

20. Platyhelminthes (plat-ih-hel-min-theez) • Most are free living and parasitic. • carnivores and parasitic • Sexual (hermaphrodites) & asexual (fission) reproduction • Bilateral body symmetry • Ectothermic or cold blooded • Marine and fresh water

21. Nematoda (nee-muh-ToHD-uh) • Most are free living and parasitic. • herbivores, carnivores and parasitic • Sexual and hermaphroditic reproduction • Bilateral body symmetry • Ectothermic or cold blooded • Live just about everywhere.

22. Mollusca (mol-us-ka) • Soft body and sometimes a hard shell Bodies are divided into 3 parts: Head, Foot, and Visceral Hump. • filter feeders, herbivores and carnivores • Bilateral symmetry • Ectothermic or cold blooded • Marine, fresh water and land

23. Arthropoda (arth-rop-a-da) • A hard outer body covering called an exoskeleton. • Specialized mouth parts. Jointed legs. Compound Eyes. Segmented body • herbivores, carnivores, ominovores • Sexual (internally and externally) reproduction • Bilateral body symmetry • Ectothermic or Cold blooded • Found in aquatic and terrestrial environments

24. Annelida (uh-Nel-ih-duh) • Soft body worms with sections, possesses a through gut, mouth and anus. • Some parasitic • Sexual and hermaphroditic reproduction • Bilateral body symmetry • Ectothermic or coldblooded • Found in soil and fresh water

25. Echinodermata(ee-Ky-noh-durmz) • Have bodies with rough skin and sharp spines, possess 5-rayed symmetry. Calcareous skeleton • Sexual (separate sexes) and asexual (regeneration) reproduction • Radial body symmetry • Ectothermic or Cold blooded • Found in marine environments
