Kingdom-Animals
Animal Characteristics
• Heterotrophs
• Multicellular
• No cell walls
• Tissues (most)
• Sexual Reproduction (most)
Remember classification
• Kingdom- Animals
• Phylum – OUR FOCUS
• Class
• Order
• Family
• Genus
• species
Phylum Porifera-sponges
*no symmetry, no tissues/organs*evol- multicellular
CnidariaJellyfish-medusa
Coral- Many polyps living together
Radial symmetryEvol- Tissues

Platyhelmithes(Flatworm)
Evol- Bilateral
Nematoda
Guinea Worm (round worm)Nematode Worms (round worms)
Evol- Pseudocoelom (mouth and anus)
Mollusca
• Evol- True ceolom (organs)
– Visceral Mass: central part with organs
– Mantle: Outer body layer
– Foot: Movement
Earthworms and Leeches! (Phylum- Annelids)
Evol- Segmentation
Arthropoda
• Evol- Jointed appendages
• The Classes– Arachnids, Insects,
Crustaceans
Echinodermata
• Evol- Deuterstome Development – (In other words they develop the same way
vertebrates do)– Also have an endoskeleton
Vertebrates(Agnatha)
• Jawless, cartilaginous bodies, ectotherm• Lampreys
VertebratesChondrichthyes
• Sharks
• Cartilaginous skeleton, gills, jaws, 2 chambered heart, internal reproduction, ectotherm
Vertebrates(Osteichtyes)
• Bones, 2 chambered heart, gills, external reproduction, ectotherm
Vertebrates(Amphibians)
• Gills + Lungs, 3 Chambered heart, external reproduction, ectotherm
Vertebrates(Reptiles)
• Lungs, Internal reproduction shelled egg, 3 chambered heart, ectotherm
Exception to ruleCrocs have a 4 chambered heart(more closely related birds)
Vertebrates(Aves)
• Lungs, Internal reproduction shelled egg, endotherm, 4 chambered heart
Vertebrates(Mammals)
• Internal development, lungs, 4 chambered heart, endotherm
