Kingdom Animalia

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

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

Phylum Cnidaria or Coelenterata n Live in water n Most have tentacles n catch food with stinging cells n 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

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

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

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 n eat soil and breakdown organic matter, wastes provide nutrients to soil

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

Phylum Arthropoda n Body divided into sections/segments n Exoskeleton n Jointed legs n well developed nervous system n largest group of organisms on earth n Phylum Arthropoda has 5 classes

Phylum Arthropoda n Class n no – Arachnida antennae n 4 pairs of legs n 2 body regions - cephalothorax & abdomen n spiders, scorpions, mites & ticks

Phylum Arthropoda Class Crustacea n Shrimp, lobsters, crabs, barnacles, isopods n 5 pairs of legs

~Invertebrate Phylum Arthropoda n n Class Insecta no antennae 3 pairs of legs grasshoppers, ants, butterflies, bees

Phylum Arthropoda n Class Diplopoda n Millipedes n segmented animals n Have 2 pairs of legs per segment

Phylum Arthropoda n Class Chilopods n Centipede n Segemented animals n Have 1 pair of legs per body segment

Phylum Chordata 5 classes § Fish § Mammals § Reptiles § Amphibians § Birds
