Transcript

  • 1. .
  • 2. General characteristics Multicellular Eukaryotic but with no cell walls Heterotrophs (consumers) With nervous system to respond to their environment Locomotion relates to ability to obtain food by moving to different places Most animals develop from a zygote to become a new organism (individual)
  • 3. Animals that are irregular in shape are asymmetrical. Animals that are regular in shape are symmetrical.
  • 4. An animal has radial symmetry if it can be divided along any plane, through a central axis, into equal halves. An animal has bilateral symmetry if it can be divided down its length into similar right and left halves forming mirror images of each other.
  • 5. Though not all animals have a skeleton, those that do not have can be divided into two groups: Those with an exoskeleton – a hard, waxy coating on the outside of the body that protects internal organs, provides a framework for support, and a place for muscle attachment. Ex. Shrimp Those with an endoskeleton – support framework within the body that protects some organs and a brace for muscles to pull against. Ex. Squid
  • 6. Phyla under Animal Kingdom
  • 7. Phylum Porifera (pore-bearing animals) Characteristics: -the simplest form of animal life -live in water -cannot move around -no symmetry -with pores (holes) all over body
  • 8. Filter Feeders: a sponge filters particles of food from water using collar cells and then pumps the water out the osculum.
  • 9. Sponges
  • 10. Sponges
  • 11. Phylum Coelenterata (Cnidaria) hollowed-bodied animals Characteristics: Live in water Most have tentacles catch food with stinging cells(nematocyst) gut for digestion
  • 12. Medusae
  • 13. Carybdea sivickisiChironex fleckeri Chiropsalmus sp. Carukia barnesi
  • 14. Coelenterates- Hydrozoans
  • 15. Cyanea capillata ->
  • 16. Polyp
  • 17. Corymorpha nutans
  • 18. Anthozoans Scypozoans
  • 19. Urticina coriacea-> <- Anthopleura sola <- Anthopleura artemisia Metridium farcimen ->
  • 20. Phylum Platyhelminthes (flatworms)  Flat, ribbon-like body  Live in water or are parasites  bilateral symmetry
  • 21. Flatworms-turbellarians
  • 22. Planaria
  • 23. Two turbellarians mating by penis fencing. Each has two penises, the white spikes on the undersides of their heads. Pseudobiseros Polyclad
  • 24. Flukes
  • 25. Liver Fluke
  • 26. Tapeworm-Taenia solium
  • 27. Life cycle of Tapeworms
  • 28. Phylum Nematoda (Nemathelminthes) Round worms Characteristics: -round, tubular body -some are small or microscopic -bilateral symmetry -have both a mouth and anus -live in water or are parasites
  • 29. Hookworm Trichinella
  • 30. Ascaris A large roundworm that lives in the intestines of pigs, horses and sometimes man Females are larger than the males and may reach a length of nearly twelve inches Ascaris eggs enter the human being in contaminated food or water They do not hatch in the stomach, but they begin to hatch within a few hours when they reach the small intestine A mature female lays about 200,000 eggs each day Ascaris seems relatively harmless in man, although occasionally a large number of adult worms twist together, block the intestine and cause death Infections are more common in children Adults become infected under conditions of lack of vitamins
  • 31. Ascariasis
  • 32. toxocariasis
  • 33. Heart worm
  • 34. Dracunculus
  • 35. Loa loa Ancyclostoma
  • 36. Elephantiasis
  • 37. Phylum Annelida (segmented worms) Characteristics: Body divided into segments(sections) Live in water or underground have a nervous and circulatory system
  • 38. Groups
  • 39. Hirudinae:The LeechHirudinae:The Leech
