1. Objective • SWBAT describe characteristics of organisms in kingdom Animalia.

2. Animals!

3. Characteristics of Animals • Animals are multicellular. • They are eukaryotes. • They are heterotrophs (only consumers). • They are the only mobilemulticellular organisms. • They have complex, specialized organs. • Specialized: performs a specific function.

4. Homo sapiens

5. Ursus maritimus

6. Uroplatus fimbriatus If disturbed, this gecko will raise its tail and head, open its mouth, and scream … to call its mother for help.

7. Bathynomus giganteus (giant isopod) • Giant isopods live on the ocean floor – up to 6,000 feet deep – where there is no light. • They feast on dead and decaying fish that sink to the bottom of the sea.

8. Check For Understanding • Which statement about animals is false? • They are multicellular. • They are eukaryotes. • They can produce their own energy. • Their cells have nuclei.

9. Animal Cells • Animal cells do not have cell walls. More flexible than plants/fungi; can move on their own • Animal cells do not have chloroplasts.  Get food by eating other organisms.

10. Trachinocephalus myops (snakefish) • Snakefish can grow to over 3 feet long. • They have a voracious appetite – they will eat all other fish in their lake or pond, even their own children. A snakefish can survive out of water for up to 3 days, slithering across land and eating small animals in its path.

11. Check For Understanding • Which statement best describes a characteristic of the organisms in kingdom Animalia? • They thrive in extreme environments and lack a nucleus. • They contain cells that have a nucleus and lack a cell wall. • They are multicellular and use chlorophyll to manufacture food. • They are unicellular and depend on other organisms for energy.

12. Sponges! But they can’t move! Actually, some species can – at speeds of about 1-4 millimeters per day, like an amoeba.

13. Daubentonia madagascariensis(Aye-aye) The Malagasy people of Madagascar consider the Aye-aye to be magical, and they believe it brings death to any village it appears in.

14. Check For Understanding • Which statement describes all members of the kingdom Animalia and some members of the kingdom Protista? • They are made of eukaryotic cells. • Their cells have cell walls. • They depend on other organisms for their energy. • They are autotrophs.

15. What’s the difference? Amoeba proteus Aldabrachelys gigantae Mobile Eukaryote Consumer Multicellular, with complex organs • Mobile • Eukaryote • Consumer • Unicellular, with no complex organs

16. Leptynia hispanica

17. Check For Understanding • A walking stick is an insect that looks like a twig from a tree. Which characteristics are best used to classify the walking stick as an animal, and not a plant? • It is mobile, and it is a consumer. • It is multicellular and eukaryotic. • Its cells have nuclei and a cell membrane. • It reproduces and makes energy using sex cells.

18. Puma concolor on Mr. D’s front lawn!

19. Check For Understanding • Which statement identifies a difference between animals and fungi? • Animals are multicellular, but fungi are not. • Animals are hetertrophs, but fungi are not. • Fungi have chloroplasts, but animals do not. • Fungi have cell walls, but animals do not.

20. Condylura cristata (star-nosed mole) This creature is blind. Its star-shaped snout has over 25,000 tiny sensory receptors that help it feel its way around, detecting food and predators.

21. Animalia • Cell number: Multicellular (many cells) • Cell type: Eukaryotic (have a nucleus) • Energy: Heterotrophs (consumers) • Key fact: They are mobile and have complex organs. • Examples: humans, fish, insects, birds, sponges
