Classification Kingdoms and Classes Classification is sorting out all organisms into groups according to the similarities between them. Organisms are divided into 6 kingdoms. In this unit we will be studying 2 of these kingdoms: the animal kingdom and the plant kingdom. Each kingdom can be further divided until the species level is reached. Do you remember what level of classification follows Kingdoms?

Animal Kingdom Invertebrates Vertebrates: Those animals with an no skeleton or an exterior skeleton (exoskeleton) and NO backbone. Vertebrates: Those animals with an internal skeleton (endoskeleton) and a backbone.
Vertebrates
Mammals Vertebrates Have body hair or fur Have mammary glands that produce milk Warm blooded
Fish Vertebrates Live in water Breathe with gills Have cartilage or bony skeleton (scales) Cold blooded Most lay eggs
Reptiles Vertebrates Have dry, scaly skins Lay eggs Breathe with lungs Cold blooded
Amphibians Vertebrates Moist skin Lay their eggs in water Larvae have gills and live in water Adults have lungs and live on land Cold blooded
Birds Vertebrates Have feathers and wings Have beak or bill Lay eggs with hard shells Breathe with lungs Warm blooded
Invertebrates are the largest group of animals on earth.
Cnidarians Invertebrates Hollow bodied Mouth is the only body opening and is surrounded by tentacles Uses sting cells to paralyse prey Cnidarians
Flatworms Round Worms Invertebrates Flat thin bodies Digestive system has only one opening Animals are both male and females Mostly parasites Flatworms Rounded bodied Bodies made of segments Round Worms
Mollusks Invertebrates Not segmented Body in three continuous parts with head, body and foot Have one or two shells Mollusks
Echinoderms Invertebrates Spiny skinned Body in five parts Central mouth with respiratory gills Echinoderms
Arthropods Invertebrates Hard exo-sekeleton on outside of body Has eyes and mouth Body divided into more than one segment Arthropods Centipedes & Millipedes Crustaceans Arachnids Insects
