1. WARM-UP: Can animals communicate with people? On your Warm-Up, write one sentence with examples if you know any. • How many of you can speak a second language? • Do you know any sign language? • Animal_Intelligencekoko gorilla.asf • http://videos.howstuffworks.com/animal-planet/32942-extraordinary-animals-cerebral-sea-lion-video.htm • http://videos.howstuffworks.com/animal-planet/28536-planets-best-dolphin-training-video.htm

2. Sign language • commtechlab.msu.edu/Sites/aslweb/browser.htm • sign language web site

3. Pretend that you are . . . . Carlos Linnaeus and you are responsible for making classifying the Animal Kingdom into smaller levels, phylums. How would you group them? Work in your groups to put the pictures of animals into groups.

4. Animals and Science

5. Intro to Animals Jars o’ animals Be very careful with these specimen Your task today is to observe and describe. The Jars o’animals are grouped into 9 phyla. Describe the characteristics (column 1)and list 4 or more of the different animals in each phylum (column 2). DO NOT write anything in the 3rd column.

6. INVERTEBRATES • STANDARD S7L1: The diversity of living organisms and how they can be compared scientifically

7. BASIC BODY PLANS OF INVERTEBRATES • Bilateral Symmetry: most animals Examples: butterfly, ant • Radial Symmetry Ex: starfish • Asymmetrical: no symmetry Ex: sponge

8. NERVOUS SYSTEM OF INVERTEBRATES • All animals have neurons, EXCEPT SPONGES • NEURONS: Allow animals to sense their environment; carry messages to control behavior; arranged in networks • GANGLION: Concentrated mass of nerve cells; each one controls a different part of the body; controlled by a brain in complex invertebrates

9. DIGESTIVE SYSTEM OFINVERTEBRATES • GUT: Pouch lined with cells that release chemicals that break down food • Coelum: In complex invertebrates, bode cavity contains the gut and other organs

10. SPONGES • Simplest invertebrates • No tissues, guts, neurons • Move 1 mm a day at the most • Feed on tiny plants & animals • Food, water, oxygen enter through pores • Regeneration of broken pieces • Reproduction: Regeneration & Sexual • Different sizes and shapes

11. Porifera - sponges • Filter feeding aquatic animals • Only three types of tissue, no organs

12. More on sponges • ..\..\..\Video Stream\animals\Animal Kingdom and Protists.asx • ..\..\..\Video Stream\animals\Sponges filter feeding.asx

13. Cnidarians / Colenderata • Soft bodies with stinging tentacles Includes: jelly fish, corals Cnidarians coral reef 1 min

14. CNIDARIAN • Poisonous stinging cells on tentacles • Complex digestive system • Simple network of nerves • Regeneration of broken parts • 2 Body Plans • Medua: swims • Polyp: attaches to surfaces • Radial Symmetry

15. Platyhelminthes Flat worms One body opening planarian Some are parasitic Includes Planarian, tapeworm

16. Flatworms • Simplest worm • 3 classes of flatworms • Planarians Freshwater Predators of other animals Well developed nervous system with a brain • Flukes • Parasite • Fertilized eggs may infect drinking water and food supply • Have special suckers & hooks for attaching to hosts • Few millimeters long

17. FLATWORMS 3. Tapeworms • Parasite • Specialized body to be a parasite • Absorbs nutrients from the host

18. Nematodaround worms • Soft, long, slender, round bodies • Bilateral symmetry • Simple nervous system with brain • Breaks down dead tissues of plants & animals • Some parasitic • Hookworms, heartworms

19. ANNELID WORMS • SEGMENTED WORMS: Earthworms, Marine worms, Leeches • Bilateral symmetry • Most complex worm • Closed circulatory with a complex nervous system and brain • Nerve cord connects the brain to ganglion in each segment • Eats plants and animals

20. ARTHROPODS • Largest group of animals on Earth • 75% of all animal species

21. 4 CHARACTERISTICS OF ARTHROPODS • Segmented body with specialized parts 3 Main Body Parts: head, thorax, abdomen 2, Jointed limbs to allow for movement • Exoskeleton: covers the outside of the body and protects the organs • Well developed nervous system and brain

22. NERVOUS SYSTEM OF ARTHROPODS • Receives information from sense organs, including eyes and bristles • Some have simple eyes that detect light • Most have compound eyes made of many identical, light sensitive units that work together

23. CLASSIFICATION OF ARTHROPODS • Classified according to the kinds of body parts they have by number of legs, eyes, antennae • Antennae: a feeler that senses touch, taste, smell

24. CENTIPEDES and MILLIPEDES CENTIPEDES MILLIPEDS Up to 752 legs • 1 pair of antennae • Hard head • 1 pair of mandibles (mouthparts that chew food) • 30 to 354 legs

25. CRUSTACEANS • Shrimp, barnacles, crabs, lobsters • Gills for breathing • Mandibles for eating • 2 Compound eyes at the end of an eyestalk • 2 pair of antennae

26. ARACHNIDS • Spiders, scorpions, mites, ticks • 2 Main Body Parts • Cephalothorax: head and thorax • Abdomen • 4 Pairs of Legs • No antennae • No mandible, but a claw like mouthpart, chelicerae • Up to 8 simple eyes • Helpful to us—predator to insects

27. INSECTS • Largest group of arthropods • 3 Main Body Parts: head, thorax, abdomen • 6 legs • 2 antennae • Compound eyes • Mandibles • May or may not have 1 or 2 pairs of wings

28. METAMORPHOSIS Complete Metamorphosis Incomplete Metamorphosis Less complicated 3 Main Stages: egg, nymph, adult Molting: nymphs may shed exoskeleton several times Nymph: looks like very small adult, but has no wings • Insects change form as they develop • Examples: butterflies, beetles, flies, bees, wasps, ants

29. Mollusks • 3 main groups of soft bodied animals • Gastropods, bivalves, cephlapods • Most have shells that grow

30. Bivalves • Bi – Two “two shells”

31. Gastro – stomach Pod – foot “I walk on my stomach” Gastropod

32. Cephalopods • Cephalo – brain • Pods – feet • “Head footed” • ..\..\..\Video Stream\animals\Octopus jeff corbin.asx

33. Annelidasegmented worms • Many in soil • Two body openings

34. And finally . . . Arthropods Jointed legs, exoskeleton, segmented bodies Includes: crustaceans, insects, arachnids

35. T. T. F. • Put your Intro to Animals WS into your notebook • Read the one page of information on the crayfish. • Count Off • Write two true statements and one false from the page of information • After the lab, answer the bottom and turn in.
