Kingdom Animalia

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

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.

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

Phylum Porifera Phylum Porifera Sponges Sponges simplest form of animal life simplest form of animal life live in water live in water Do not move around Do not move around no symmetry no symmetry Pores (holes) all over body Pores (holes) all over body Examples: Tube Sponge, Glass Sponge, Sea Sponge Examples: Tube Sponge, Glass Sponge, Sea Sponge

Phylum Cnidaria or Coelenterata Live in water Live in water Most have tentacles Most have tentacles catch food with stinging cells catch food with stinging cells Examples - Jellyfish, Hydra, sea anemones, and corals Examples - Jellyfish, Hydra, sea anemones, and corals

Phylum Platyhelminthes  Flatworms  Flat, ribbon-like body  Live in water or are parasites  bilateral symmetry  Examples: Planaria  eyespots detect light  food and waste go in and out the same opening

Nematoda Phylum Nematoda Roundworms Roundworms –Round, tubular body –small or microscopic –bilateral symmetry –have both a mouth and anus –Live in water or are parasites Examples: Examples: –Hookworm –Trichinella

Phylum Mollusca Soft bodies Soft bodies Hard Shells Hard Shells Live on land or in water Live on land or in water Important food source for humans Important food source for humans Phylum Mollusca has three classes Phylum Mollusca has three classes

Phylum Mollusca Class Gastropoda Or Univalves –snails and slugs –may have 1 shell –stomach-footed - move on stomach

Phylum Mollusca Class Bivalves –2 shells hinged together –clams, oysters, scallops and mussels

Mollusca Phylum Mollusca Class Cephalopods –squids and octopuses –internal mantel

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

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
