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.
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.
Slide three: activities
controlling soil nutrient cycling and controlling harmful species. And many more
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
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.
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
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

(I understand that I did get an answer from yahoo answers but it was from a scientist with a major in botany, and biology. He is one of Yahoo’s most valuable sources. He explained the geneology of Nemotada)
