THE ANIMAL KINGDOM Ms. Fisher Characteristics of ALL Animals Multi-cellular Eukaryotic (nucleus) Consumers- cant make their own food, receive energy by eating other organisms Mobility **Most animals have symmetry

This chapter we are discussing invertebrates, simple animals! All animals belong to one of two groups: Invertebrates or vertebrates(chordates) complex 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 2. STINGING-CELL ANIMALS Coelenterata (c-len-ter-a-ta)

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

Jellyfish Symmetry Radial Originates from a center point Bilateral Divided into 2 equal sides (all vertebrates

& some invertebrates 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 4. Roundworm

Round in shape hookworm Separate mouth and anus Bilateral symmetry Example: Ascaris Parasitic roundworm Causes death in 3rd world countries 5. Segmented Worms (most complex of all worms)

Body divided into segments Live anywhere (land, fresh + salt water) Examples: Earthworm Leech parasite Earth Worm Grinds food

Digest Holds food Agenda: 10-24 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 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, snail octopus Soft bodied Animals: Grouped into 3 classes based off of the following traits: Kind of foot If a shell is present

And # of shells 1 Class: Snails & Slugs st Wide muscular foot Single shell-snails, slugs no shell * differ eyes 2 Class: Clams nd

Two shells Foot shaped like a shovel & is used to bury themselves in sand 3 Class: Octopus & Squid rd No shell Muscular foot divided into arms Move by shooting a jet of water

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 INVERTEBRATES 1. 2. 3. 4. 5. 6.

Phylum: Sponges Phylum: Stinging cell Phylum: Flatworm Phylum: Roundworm Phylum: Segmented worms Phylum: Mollusk (soft-bodied) Simple Animals 7. Phylum: Arthropods Class

Insecta Arachnid Crustacean 8. Phylum: Echinoderms Starfish Complex, Invertebrates 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

Complex Invertebrates: 7. Arthropod Class: Arachnid 8 legs ( 4 pairs) No antennae 2 body segments Spiders, scorpions, ticks Arthropod Class: Insecta 6 legs (3 pairs) 3 body segments

2 pairs of wings (most) Arthropod Class: Crustacea Mostly Marine animals 2 pairs of Antennae

4 pairs of walking legs Some...1 pair of pinchers Crab, lobster, shrimp, crayfish Monday: 10-27-14 Agenda: Complete Our Note Taking On Invertebrates Buddy up and do Invertebrate Lab If time allows. Conclude w/ completing invertebrate

worksheets -Types of Invertebrates -Invertebrates Word Search TEST ON INVERTEBRATES WEDNESDAY 8.Spiny skin/ Echinoderm ec-ino-derm Radial symmetry Spines on skin 5-part body Tube feet used for movement, feeding, attachment.

Example: starfish ALL ARE INVERTEBRATES 1. 2. 3. 4. 5.

6. 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 Complex Animals 9. Vertebrates (Chordates)
