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

Animals have stinging tentacles Sexual reproduction Have “mouth” structure Radial symmetry Anemone Jellyfish Hydra

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 Example:
“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 3rd world countries

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

9 Earth Worm Grinds food Digest Holds food

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

11 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, snail octopus

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

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

15 3rd 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 7. Phylum: Arthropods Phylum: Sponges
Phylum: Stinging cell Phylum: Flatworm Phylum: Roundworm Simple Animals Phylum: Segmented worms 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

Phylum: Sponges Phylum: Stinging cell Phylum: Flatworm Phylum: Roundworm Phylum: Segmented worms 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 9. Vertebrates (Chordates)
