Animalia kingdom modified

  1. 1. Animalia Kingdom
  2. 2. Animals Do not have chlorophyll. Can move about freely from place to place (except the fixed sponges , corals , etc.) Cannot make their own food and so have to feed on plants or on other animals. Have special digestive organs because they have to digest and absorb the ingested readymade food. No cellulose cell wall. Only the cell membrane is present . They respond quickly to external stimuli.
  3. 3. Major differences between vertebrates and invertebrates. Vertebrates Invertebrates 1. They have an internal skeleton. 1.No internal skeleton . 2. A backbone is present. 2. Backbone is not present. 3. A tail is usually present. 3. Tail is absent (anus at the tip of the back end of the body.) 4. Heart is on the ventral side of the body. 4. Heart when present, is on the dorsal side of the body. 5. Nerve (spinal) cord is dorsal, and hollow. 5. Nerve cord is ventral and solid. 6. They have two pairs of limbs. 6. They have three or more pairs of limbs, if present. 7. Haemoglobin in red blood cells. 7. Haemoglobin , if present, dissolved.
  4. 4. Vertebrates
  5. 5. Invertebrates
  8. 8. 1.PORIFERA: Porifera are the simplest multicellular animals. Their body consists of a hollow tube. There is no single mouth but many pores or canals are present in the body wall, through which water enters. The sponges usually have a skeleton of microscopic spicules or elastic spongin fibres . Except one or two fresh water sponges, all are found in sea.  Ex: Sycon,Bath sponge, etc.
  9. 9. 2.COELENTERATA/CNIDARIA: In cnidarians,a two-layered body wall encloses a single cavity in which digestion takes place.The cavity opens by a mouth at one end only. There are tentacles to catch food organisms. The cnidarians are found in water (mostly in sea,very few in freshwater).Ex:Sea-anemone, Jellyfish and Red Coral(“moonga”).
  10. 10. 3.PLATYHELMINTHES: These are small,soft,flattened,unsegmented worms without a body cavity. The alimentary canal has only one opening,the mouth. Most of the flatworms live on or inside other animals as parasites,but a few are free,living in the sea or freshwater.Ex:Parasites-Liverfluke,Tapeworm;free living-Planarian.
  11. 11. • They are long , cylindrical and unsegmented , without a body cavity. • The alimetary canal opens at the two ends , mouth and anus. • They are mostly parasatic but some live in free soil. • Examples : Hookworm, Ascaris in humans, eelworms in potato plants.
  12. 12. ANNELIDA • The body of an annelid worm is cylindrical and divided into ring like segments. • An annelid worm has a well developed digestive system with the alimentary canal open at both the ends, with a mouth and anus. • They have a true body cavity, the coelom. • Example : leech, earthworm, nereis
  13. 13. ARTHROPODA • This phylum has the largest number of species in the animal kingdom. • These animals have joined limbs, one pair each on some or all body segments. • There is an exoskeleton made of chitin. • They cast of their exoskeleton during growth in early life, which is regrown. • The casting off and regrowing of the exoskeleton is collectively called moulting • Examples: crab, butterfly, crayfish
  14. 14. MOLLUSCA • These animals have a soft, unsegmented body, with a hard calareous shell to protect the soft body. • They have a muscular foot to help them in locomotion and also act as a weapon in some cases.
  15. 15. Phylum Echinodermata  Echinoderms are unsegmented , marine animals.  They have an exoskeleton and a spiny Surface.  They move by means of tube-feet .  They are radially symmetrical, i.e. they have similar parts arranged regularly around a central point.  Example-Starfish , Brittle star ,Sea urchin , Sea cucumber.
  16. 16. Phylum Chordata  All chordates possess a notochord which is a rod-like structure present in the mid-dorsal axis of the body.  The chordates which possess a backbone are called Vertebrates.  Vertebrates have a well developed vertebral column forming the main axis of their internal skeleton , which may be of bones or cartilage.  Example-Bird ,Fish ,Reptile ,etc.
  17. 17. Vertebrate classes  The vertebrates are divided into five classes  Pisces  Amphibia  Reptile  Aves  Mammalia
  18. 18. Class Pisces  The class Pisces includes fishes . They are completely adapted to aquatic life.  They have a two-chambered heart , breathe by means of gills , and are cold-blooded .  There body is covered with scales .  They have fins but no limbs.
  19. 19. Fish  Fishes are of two types:  Cartilaginous fishes: whose skeleton is made of cartilage , e.g. Sharks , Dogfish , Skates .  Bony fishes: whose Skeleton is made of bones , e.g. Carps , Roaches , Herring , Trouts.
  20. 20. Amphibia Amphibians live partly on land and partly on water. They have five fingered (pentadactyl) limbs and three -chambered heart. They are cold-blooded. Eg:-midwife toad salamander tree frog
  21. 21. Reptilia Reptiles are completely adapted to life on land. They have rough, horny scales on the skin, and a three-chambered heart. They are cold-blooded. Eg:- lizard snake turtle
  22. 22. Aves All the birds belong to this class. Their fore-limbs are modified into wings. They have scaly legs and a four-chambered heart. They are warm-blooded or homeothermal. Eg:-myna , hoopoe sunbird
  23. 23. Mammalia Mammals are the most highly developed animals for life on land, water and air. They have hair on their skin and have a four-chambered heart. They are warm-blooded. Eg:- seals whales bats
