Kingdom Animalia G.Burgess 2010.

Characteristics Eukaryotic No cell walls Multicellular Heterotrophic Most are motile, some sessile Nervous regulation Reproduction: sexual, asexual by budding, parthenogenesis

Classification Classification is based on; physical structure(invertebrate, vertebrate, hydrostatic skeleton, endoskeleton or exoskeleton) Body organization(tissues, organ, organ system, segmented or nonsegmented) Number of body layers (2or3 layers) Body symetry (bilateral or radial) organ system (organization and function) Digestive system (stomach or gizzard and crop) Nervous system(brain, ganglia, nerve network) Circulatory system(open or closed, 2_3_4 chamber heart) Reproductive process (asexual: budding, parthenogenisis, sexual: egg laying, marsupial, live birthing)

Invertebrate Classification *Phylum Porifera (sponges: without tissues) *Phylum Cnidaria (jellyfish: tissue) Phylum Platyhelminthes (flatworm, tapeworm: organ system) Phylum Nematoda (round worm, pin worm : organ system) Phylum Rotifera (rotifers : organ system) *Phylum Mollusca (clam, octopus : organ system) *Phylum Annelida (earthworm : organ system) *Phylum Echinodermata (starfish : organ system) *Phylum Arthropoda (fly, spider, lobster : organ system)

Vertebrate Classificaton Phylum Chordata; phylum divided into classes Class Chondrichthyes (sharks, rays: Cartilagenous skeleton, gills) Class Osteichthyes (salmon, Trout: Bony skeleton, gills) Class Amphibia (frog, salamander: bony skeleton, aquatic, lungs) Class Reptilia (snake, turtle: bony skeleton, aquatic or terrestrial) Class Aves (eagle, crow: bony skeleton, lungs, terestrial) Class Mamalia (cow, human: bony skeleton, lungs, live birth, has hair)
