Presentation Transcript

  1. Adaptations in Animals

  2. Sponges

  3. Sponges • Transport and excretion: Diffusion • Gas exchange: Respiration • Nutrition: Filter feeders • Reproduction: Sexual • sponges

  4. Cnidarians

  5. Cnidarians • Transport and excretion: Diffusion • Respiration: Aerobic respiration • Digestion: Use nematocysts for digestion • Reproduction: Asexual or sexual • Nematocyst • Box Jelly

  6. Flatworms

  7. Flatworms • Transport and excretion: Digestive tract (finally!) • Respiration: Aerobic respiration • Nutrition: Mouth and digestive tract (but only one opening!!!) • Reproduction Growth and Development: Sexual reproduction externally • Flatworm sex • tapeworm

  8. MollusksOctopus

  9. Transport and excretion • Transport and excretion: closed circulatory system for transport and nephridia for excretion

  10. Mollusks • Respiration: Gills or lungs (depending if on land or in water) • Nutrition: Filter feeder or through mouth (radula) • Reproduction: Sexually externally

  11. Segmented worms

  12. Transport and Excretion • Closed circulatory system, digestive system and anus

  13. Segmented Worms • Respiration: Skin • Nutrition: Mouth and anus • Reproduction: Sexually using eggs and sperm • Annelids

  14. Arthropods Insects, crustaceans and arachnids

  15. Transport and excretion • Open circulatory system (they are small) • Digestive system and anus

  16. Respiration • Tracheal tubes, spiracles, book lungs or gills in underwater crustaceans

  17. Nutrition • Mouthparts specialized for eating

  18. Reproduction • Sexually internally or externally • Praying Mantis male gets eaten • Barnacle

  19. Fish

  20. Fish • Transport and excretion: Closed circulatory system, digestive tract, anus, urinary tract • Small intestine absorbs most nutrients • Respiration: Gills • Nutrition: Mouth with jaws for eating (first one!) • Reproduction: Sexually mostly external fertilization

  21. Amphibians Frogs and Salamanders

  22. Amphibians • Transport and excretion: closed circulatory system, digestive tract, anus, urinary tract • Small intestine absorbs most nutrients • Respiration: gills as tadpoles, lungs and skin as adults • Nutrition: Jaws with long tongue • Reproduction: Sexually external fertilization

  23. Reptiles • Transport and excretion: Closed circulatory system, digestive tract, anus, urinary tract • Small intestine absorbs most nutrients • Respiration: Lungs

  24. Nutrition • Specialized jaws

  25. Reproduction, growth and development • Sexual reproduction internally and produce amniotic eggs

  26. Birds

  27. Birds • Transport and excretion: Closed circulatory system, complete digestive tract, anus, urinary tract • Small intestine absorbs most nutrients • Respiration: Lungs with air sacks • Nutrition: Beaks or bills for obtaining food • Reproduction growth and development: Internal sexual reproduction and form a hard amniotic egg

  28. Placental Mammals • Transport and excretion: Closed circulatory system, complete digestive tract, anus, urniarytract • Small intestine absorbs most nutrients • Respiration: Lungs • Nutrition: Jaws with different types of teeth • Reproduction: Sexually with placenta to give birth to live young

  29. Marsupials • Everything is the same as placental mammals except they give birth to young very early and the young live in their pouch

  30. Monotreme • Transport and respiration are the same…. • but they have long snouts or duckbills for nutrition and lay eggs for reproduction
