1. Kingdom Animalia

2. Characteristics Multicellular Multicellular Eukaryotic with no cell walls Eukaryotic with no cell walls Heterotrophs (consumers) Heterotrophs (consumers) Have a nervous system to respond to their environment Have a nervous system to respond to their environment Locomotion relates to ability to obtain food Locomotion relates to ability to obtain food

3. Protection and Support Though not all animals have a skeleton, those that do can be divided into two groups: Though not all animals have a skeleton, those that do can be divided into two groups: –Those with an exoskeleton – a hard, waxy coating on the outside of the body that protects internal organs, provides a framework for support, and a place for muscle attachment. –Those with an endoskeleton – support framework within the body that protects some organs and a brace for muscles to pull against.

4. In the Animal Kingdom there are 9 Phyla Porifera Cnidaria Platyhelminthes Nematoda Annelida Mollusca Echinoderm Arthropoda Chordate

5.

13. Phylum Annelida –Segemented worms –Body divided into segments(sections) –Live in water or underground –have a nervous and circulatory system eat soil and breakdown organic matter, wastes provide nutrients to soil eat soil and breakdown organic matter, wastes provide nutrients to soil

14. Phylum Echinodermata Hard, spiny skin Hard, spiny skin Live in salt water Live in salt water Radial symmetry Radial symmetry name means ‘spiney skinned’ name means ‘spiney skinned’ endoskeleton endoskeleton Examples: seastar, sea urchin, sand dollar and sea cucumber Examples: seastar, sea urchin, sand dollar and sea cucumber
