Transcript

  • 1. Siddhu Kandan
  • 2. Slide One : Profile
    • Hi, I am part of the Nematoda phylum,
    • We look like very simple folk, but we are complex individuals. We are found everywhere from intestines, to the Antarctic.
      • We are also the second most diverse group of animals. (falling behind arthropods) There are 20,000 different species of discovered roundworms alone.
  • 3. Slide two: Habitat – Through rain, sleet, and snow…… and more
    • We are not very picky on our dwellings and can be situated anywhere from the Antarctic, to ocean tranches, to gardens, to the inside of other animals.
  • 4. Slide three: activities
    • Pros
      • controlling soil nutrient cycling and controlling harmful species. And many more
    • Cons
      • Reason for loss of agricultural production, pasture and turf damage, invasion of forest trees, adverse effects on the health of wild and domestic animals and humans.
    • To be frank
      • We eat, sleep, reproduce, and die
  • 5. Slide four: ancestors
    • We’ve been here before the Carboniferous period (354 to 290 Million Years Ago)
    • We are the first animals with a complete digestive system that has two openings--the mouth and the anus
      • We don't have to finish digesting and expelling wastes from one meal before it can eat another. I can have food in various stages of digestion all at the same time.
    • We take food in through the mouth, digest it in the intestine, and pass undigested food waste out of the body through the anus.
  • 6. Slide five: structures
    • We have much less cell multiplication - cell enlargement
    • Don’t have a defined circulatory system – fluid is pushed
    • nematode’s muscle cells branch toward the nerve cells
    • 16 sensory organs
  • 7. Slide Six – Ideal mate
    • Male view: large females
    • Female view: small males with bent tails
    • Willing to go through a six stage cycle
    • Variety of sex organs depending on species
      • Willing to adapt to different environments
  • 8. Helpful websites/citations
