1 THE ANIMAL KINGDOM Ms. Fisher

2 Characteristics of ALL Animals… Multi-cellular Eukaryotic (nucleus) Consumers- can’t make their own food, receive energy by eating other organisms Mobility **Most animals have symmetry All animals belong to one of two groups: Invertebrates or vertebrates(chordates) complex This chapter we are discussing invertebrates, simple animals!

3 PART 1: Simple Animals Invertebrates 1. SPONGES: no symmetry Most simple of all animals Feed, breathe, and eliminate waste through pores Traps what it needs as water flows thru Sexual and asexual reproduction

4 2. STINGING-CELL ANIMALS Animals have stinging tentacles Sexual reproduction Have “mouth” structure Radial symmetry Anemone Hydra Jellyfish

5 Symmetry Radial Originates from a center point Bilateral Divided into 2 equal sides (all vertebrates & some invertebrates have bilateral)

6 3. Flatworm Flat in shape Bilateral symmetry Cephalization –“head” structure Example: a. Tapeworm –Parasitic- live on another living thing –Intestines –Can be very long b. Planarian –non-parasitic –found in freshwater –mouth/anus same structure

7 4. Roundworm Round in shape “hookworm” Separate mouth and anus Bilateral symmetry Example: –Ascaris Parasitic roundworm Causes death in 3 rd world countries

8 5. Segmented Worms (most complex of all worms) Body divided into “segments” Live anywhere (land, fresh + salt water) Examples: EarthwormLeech parasite

9 Earth Worm Holds food Grinds food Digest

10 Agenda: Friday Objective: Identify the 9 Major phyla of animals and give an example of each 1.Sponges 6. Soft Bodied/Mollusca 2.Stinging 7. Jointed-leg/Arthropoda 3. Flatworms 8. Spiny Skin/Echinoderms 4.Round Worms 9. Chordate 5. Segmented Worms 9 Major Phyla.docx 9 Major Phyla.docx

11 6.Soft-Bodied Animals (a.k.a. Mollusks) Soft body- have a soft body protected by a hard shell- also invertebrates Usually protected with a hard shell Muscular foot for movement Examples: clam, oyster, scallop, slug, snailoctopus

12 Soft bodied Animals: Grouped into 3 classes based off of the following traits: Kind of foot If a shell is present And # of shells

13 1 st Class: Snails & Slugs Wide muscular foot Single shell-snails, slugs no shell * differ eyes

14 2 nd Class: Clams Two shells Foot shaped like a shovel & is used to bury themselves in sand

15 3 rd Class: Octopus & Squid No shell Muscular foot divided into arms Move by shooting a jet of water

16 Review: Features of soft bodied animals/Mollusca: All are invertebrates Most have one or two shells Most have a foot they use to move about

17 INVERTEBRATES 1.Phylum: Sponges 2.Phylum: Stinging cell 3.Phylum: Flatworm 4.Phylum: Roundworm Simple Animals 5.Phylum: Segmented worms 6.Phylum: Mollusk (soft-bodied) 7. Phylum: Arthropods Class –Insecta –Arachnid –Crustacean Complex, Invertebrates 8. Phylum: Echinoderms –Starfish

18 Arthropods (Jointed-legs) Invertebrate Largest phyla (3/4 of all animals on earth!!) Exoskeleton –Segmented body Head Thorax Abdomen Bilateral symmetry Appendages –Legs, wings, antennae Grow by molting

19 Complex Invertebrates: 7. Arthropod Class: Arachnid 8 legs ( 4 pairs) No antennae 2 body segments Spiders, scorpions, ticks

20 Arthropod Class: Insecta 6 legs (3 pairs) 3 body segments 2 pairs of wings (most)

21 Arthropod Class: Crustacea Mostly Marine animals 2 pairs of Antennae 4 pairs of walking legs Some...1 pair of “pinchers” Crab, lobster, shrimp, crayfish

22 8.Spiny skin/ Echinoderm Radial symmetry “Spines” on skin 5-part body Tube feet used for movement, feeding, attachment. Example: starfish

23 ALL ARE INVERTEBRATES 1.Phylum: Sponges 2.Phylum: Stinging cell 3.Phylum: Flatworm 4.Phylum: Roundworm 5.Phylum: Segmented worms 6.Phylum: Mollusk (soft-bodied) 7. Phylum: Arthropods Class –Insecta –Arachnid –Crustacean 8. Phylum: Echinoderms –Starfish NOW, TO DISCUSS VERTEBRATES…

24 9. Vertebrates (Chordates) Complex Animals
