PRESENTATION OUTLINE

NEMATODA

BY:BRIANA NELSON

Nematode: aka, roundworms literally they are round in shapes and they are a worm type thing. They are surrounded by a strong, flexible noncellular layer that is their protection basically, and they have a very simple body plan.

How do they move around?
They move by contracting the muscles on their bottom side/belly. They also move by thrashing around and being quite cray cray.

Most nematodes are dioecious. ..big word here...Fertilization takes place when males use special copulatory spines to open the females' reproductive tracts and inject sperm into them. The sperm are unique in that they lack flagellae and move by pseudopodia, like amoebas. Development of fertilized eggs is usually direct.

We have too many!...
One study reported around 90,000 individual nematodes in a single rotting apple. Another reported 236 species living in a few cubic centimeters of mud. The number of described species is around 12,000, but too little attention has been paid to these animals and the true number may be closer to 500,000. That's just gross... And way too many we need to go on nematode control here or something.
