What is a Nematode?

So, what is a nematode? Nematodes are animals, worms to be precise, and numerous ones at that. Experts estimate there are more than a million different species of nematodes. In fact, 4 out of every 5 animals are nematodes making them the most numerically abundant animals on the planet - by a lot. They can be found absolutely everywhere from the deepest part of the ocean to the top of the highest mountain.
