CNIDARIA Domain:Eukaryota Kingdom:Animalia Phylum:Cnidaria

Structure& Characteristics Multicellular Live in fresh and salt water Have stinging cells called nemocytes Radial Symmetry

Characteristics Reproduction: Aesexual: Reproductive Budding Sexual: Medusa Stage Feeding/Digestion: Heterotrophs Uses nemocytes to catch food

Body Systems Gastrovascular Cavity Single opening for waste and ingestion No Circulatory System Nervous System Lacks organs Has simple muscles and nerves called a neural net

Stages of Cnidaria Medusa Free swimming structure umbrella shaped body and tentacles Polyp: Sessile attached to sea floor lives in large colonies

Stages of Cnidaria Examples of Polyps: Sea Anemones Corals Examples of Medusas: Jellyfish

Subgroups 4 Different Subgroups: Hydrozoa, Schyphozoa, Anthozoa, Cubozoa

PORIFERA Domain:Eukaryota Kingdom:Animalia Phylum:Porifera

Structure& Characteristics Multicellular Aquatic Asymmetrical and radial symmetry Tissues loosely organized No internal organs Chonanocytes (collar cell)

Structure Layer of flat cells Layer of cells with flagella Hollow chamber

Characteristics Cellular mobility Sessile Neither protostome nor deutrosome Heterotroph Filters bacteria Reproduction Asexual Buds Sexual Sends out sperm and egg

Body Systems No circulatory system water current No waste disposal pores No nervous system

Subgroups Glass sponges Calcareous sponges Demosponges
