  1. Hello,I am Francis. I will introduce the morphology of Molluscs Echinoderms and Chordates to you !! Biology

  2. Vertabrate Invertabrate

  3. Vertabrate Mammal Bird Fish Amphibian Reptile

  4. Invertabrate Echinodermata Molluscs

  5. Starfish Tapering arm Mouth

  6. Closed picture of starfish

  7. Charcteristics • Has many short,hard and blunt spines • Has eyespot for sensation of light

  8. Structure of starfish

  9. Adaptive features

  10. Morphology of the starfish

  11. MoluscaBivalve Shell Morphology

  12. Characteristics of Bivalves • Bilateral symmetrical • Have gill • With hard shell • With foot

  13. closed picture of mussel

  14. Internal structure of Oyster

  15. Chiton

  16. Cuttlefish

  17. Snail

  18. Adaptive features

  19. Zebra Mussel

  20. Structure of mussel and Oyster More…

  21. Fish

  22. Adaptive features

  23. gills on this great white shark can be seen as vertical slits on the shark's side.

  24. Gill of fish Fishes undergo gaseous exchange by respiration with gills

  25. Swimming bladderFunction?? - assist to supply extra oxygen to fish living stagnant water

  26. Lateral line Function: Serves as a “distance touch”in water for detecting and locating objects and moving animals

  27. Morphology of fish

  28. Photo of amphibian GiantMonkeyTreeFrog Salamander

  29. Web hand digit Function??? • Provide large surface Then? • Help to push against water when swimming

  30. Frog Life Cycle

  31. Characteristics of Frog • Streamlined body • Skin with mucus • Withwebs • Lung,skin and buccal surface for respiration

  32. Skeleton of amphibians • both bony and cartilaginous components in different ratio (depends on strength required for locomotion)

  33. Adaptive features

  34. Salamander • have a largely cartilaginous skeleton Frog • more rigid and bony to withstand the impact of jumping and landing

  35. Generalized Anatomy of a Reptile

  36. PHOTO OF REPTILE

  37. Nearly all reptiles have three- chambered hearts • Crocodilians have four-chambered hearts.

  38. Morganucodon

  39. Characteristics of reptile • most lack external ears • breathe with lungs • Dry and tough skin • have backbones or spinal columns. Except for snakes • covered with scales

  40. Skeletal FeaturesAll reptiles have backbones or spinal columns. Except for snakes, reptiles have paired limbs that typically end in five-clawed fingers or toes. Most reptiles have a pelvis that is associated with at least two spinal bones.

  41. Heat Location With Pit Organs

  42. Adaptive features

  43. Sense • sight is important for hunting • Some organisms like bat,eyes have been lost or have become greatly reduced • Amphibians are very susceptible to temperature and pressure change

  44. Different styles of foot

  45. Bird

  46. Structure of bird

  47. Adaptive features

  48. Characteristics of bird • with feathers and wings • have four-chambered hearts • warm-blooded • feathers are waterproof
