Understanding Biological Classification: Kingdoms and Classes of Organisms
Explore the fascinating world of biological classification, where organisms are systematically sorted into groups based on their similarities. Organisms are classified into six main kingdoms: Animalia, Plantae, Fungi, Protista, Archaea, and Bacteria. Each kingdom can be further divided into phylum, class, order, family, genus, and species. We delve into the characteristics of various animal groups, including vertebrates and invertebrates, and highlight specific examples from mammals to arthropods, providing a comprehensive overview of life forms on Earth.

ClassificationKingdoms and Classes Objective: Classification is sorting out all organisms into groups according to the similarities between them. Organisms are divided into 6 main kingdoms: which in turn can further be divided until species level is reached

Animals Vertebrates Invertebrates
Mammals Vertebrates • Have body hair or fur • Have mammary glands that produce milk • Warm blooded
Fish Vertebrates • Live in water • Breathe with gills • Streamlined bodies • Have cartilage or bony skeleton • Cold blooded • Mostly lay eggs
Reptiles Vertebrates • Have dry, scaly skins • Egg laying • 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 • Lay eggs with hard shells • Breathe with lungs • Warm blooded
Animals Vertebrates Invertebrates
Invertebrates • Hollow bodied • Mouth is the only body opening and is surrounded by tentacles • Uses sting cells to paralyse prey Cnidarians
Invertebrates • Flat thin bodies • Digestive system has only one opening • Animals are both male and females • Mostly parasites Flatworms
Invertebrates • Rounded bodied • Bodies made of segments True Worms
Invertebrates • Not segmented • Body in three continuous parts with head, body and foot • Have one or two shells Molluscs
Invertebrates • Spiny skinned • Body in five parts • Central mouth with respiratory gills Echinoderms
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
Animals Invertebrates Vertebrates Cnidarians Mammals Flatworms Fish True worms Reptiles Molluscs Amphibians Echinoderms Birds Arthropods
