  2. IMPORTANCEOFANIMALCLASSIFICATION • So far, over 10 lakhs of animal species have been identified and described. They show a lot of diversity in structure, habits, habitats and life styles. Hence, it is very essential that every organism be given a name and classified in a systematic way. A systematic classification of organisms will help for a better understanding of the diversity of organisms and their relations. ARISTOTLE LINNAEUS

  3. ANIMAL CLASSIFICATION CHART

  4. PROTOZOA • The term Protozoa refers to “first animals”. • Protozoans were first discovered by Anton Van Leeuwenhoek in 1671. • These are single celled animals. E.g. Amoeba Paramoecium Euglena. AMOEBA EUGLENA PARAMOECIUM

  5. PORIFERA 1. These are multicellural organisms 2. Many minute pores are present on their body. 3. They remain fixed, attached to a substatum. Eg. Sponges CYCIN GROUP SPONGES Life Cycle of sponge

  6. COELENTERATA GREEN HYDRA 1. Body is made up of two layers. They are diploblastic animals. 2. These are have tentacles are present around the mouth. 3. Body cavity is called gastrovscular cavity or coelenteron. Coelom is absent. HYDRA SEA ANIMONE

  7. PLATYHELMINTHES • These are leaf and ribbon like flattened worms. • In the body 3 layers are present, so they are called triploblastic. EX. Tape warm Fasiola. FASIOLA TAPE WARM

  8. NEMATHELMINTHES • The body is cylindrical, round in shape. • Cuticle covers the body. • This cavity is formed between body wall and the digestive system. Eg. Round warms. (Ascoris) BLOOD FLUKE ENTIROBIUS

  9. ANNELIDA LEECH • Body is divided into ring-like segments. • Various organs are arranged metamerically in the body. • Body wall is covered by cuticle. • All are triploblastic. Eg.Earth worm. Leech. BLOOD SUCCER EARTH WARMS

  10. ARTHROPODA • The body is differentiated into Head, Thorax and Abdomen. • All arthropods have jointed legs. • Body is covered by chitinous exoskeleton. Eg. Centipede, Scorpion, Arthropod a, Cockroach, housefly. ARACHNAID CENTIPEDE HOUSEFLY

  11. ARTHROPODA SCORPION ANT BUTTER FLY HONEY BEE

  12. MOLLUSCA • More often the soft body is enclose hard shell. • They live in sea and fresh water. • Animals belonging to Mollusca were first discovered by Aristotle. • Locomotion is by a muscular foot. Eg. Snail, Pila,Octopus SNAIL LIONED CHITON OCTOPUS

  13. ECHINODERMATA • These are marine animals. • They have spiny projections on their body. • Adults exhibit pentamerous radial symmetry. Eg. Starfish Antedon STAR FISH ANTEDON STAR FISH

  14. PISCES • These are aquatic animals. • The skin is covered with scales. • These animals have two chambered heart. • The body temperature of these animals is not constant and changes with sorroundings. So they are called cold-blooded animals. Eg. Shark SHARK

  15. AMPHIBIA • They live both in water and on land. • The skin is moist and without scales. • These animals have three chambered heart and they are also cold-blooded aniimals. Eg. Frog.

  16. REPTILES • The body is covered with scales. • Two pairs of llimbs are present. • These animals also have three chambered heart and they are also cold-blooded animals Eg. Lizard, Snake, Crocodile. crocodile viper

  17. REPTILES

  18. AVES • The body is covered with feathers. • The fore-limbs are modified into wings to fly in air. • The mouth extens forwards in the shape of a beak. • These animals have four chambered heart and they are warm-blooded animals. Eg. Sparrow, Pigeon, Peacock. PARROT OSTRICH

  19. AVES

  20. MAMMALS • The body is covered with hair. • They have Mammary glands, four kinds of teeth . • They are warm-blooded animals. • Diaphragm and external ear present. Eg. Man, Monkey, Blue whale, DOLPHIN
