THE ANIMAL KINGDOM Ms. Fisher
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!
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 Jellyfish Hydra
Symmetry Radial Originates from a center point Bilateral Divided into 2 equal sides (all vertebrates & some invertebrates have bilateral)
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
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 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
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
1st Class: Snails & Slugs Wide muscular foot Single shell-snails, slugs no shell * differ eyes
2nd Class: Clams Two shells Foot shaped like a shovel & is used to bury themselves in sand
3rd Class: Octopus & Squid 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 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
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 NOW, TO DISCUSS VERTEBRATES… 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…
