Two big groups Invertebrates • They have no backbone 97 % of animals There

Invertebrates the 7 phyla are: 1. 2. 3. 4. 5. 6. 7. Porifera (sponges)

Vertebrates (Chordata) There are 5 classes of vertebrates Class Fish Class Amphibia Class Reptilia

Animal basics • Multi-cellular organisms w/tissues and usually organs and organ systems • Undergo

Larval development (metamorphosis) means that the young look very different from the adult. EX:

The Animal Kingdom 8 phyla to know Zoology is the branch of science that studies animals

Two big groups Invertebrates • They have no backbone 97 % of animals There are 7 phyla Vertebrates (The Chordata phyla) • They have a backbone 3 % of animals

Invertebrates the 7 phyla are: 1. 2. 3. 4. 5. 6. 7. Porifera (sponges) Cnidaria (jellyfish) Platyhelmintes (flat worms and round worms) Annelida (segmented worms) Mollusca (clams, mussels, snails, Arthropoda (crabs, lobster, insects, spiders) Echinodermata (Sea Urchin, Sand Dollar)

1) Porifera

2) Cnidarian

3) Platyhelmintes

4) Annelida

Our representative Invertebrate • We will virtually dissect an earthworm to see the basic animal anatomy

5) Mollusks

6) Arthropods

7) Echinoderms Sea urchin Sand dollar

Vertebrates (Chordata) There are 5 classes of vertebrates Class Fish Class Amphibia Class Reptilia Class Aves Class Mammalia

Animal basics • Multi-cellular organisms w/tissues and usually organs and organ systems • Undergo larval or embryonic development

Larval development (metamorphosis) means that the young look very different from the adult. EX: caterpillars------ butterflies. -

Embryonic development • Embryos from Greek: plural "that which grows, " • This type of development means that the young version is a mini-version of the adult
