Examples of Nematodes

Meaning and Definitions

Nematodes, also known as roundworms, are non-segmented worms belonging to the phylum Nematoda. They are one of the most abundant and diverse groups of animals on Earth, found in various habitats including soil, freshwater, and marine environments.

In biology, nematodes refer to a large group of worms characterized by their long, cylindrical bodies and tapering ends. They have a simple digestive system, a nervous system, and their reproductive system can be either dioecious (separate sexes) or monoecious (both sexes in one individual).

Nematodes play significant roles in ecosystems, acting as decomposers, parasites, and predators, depending on the species. Some nematodes are considered beneficial as they contribute to nutrient cycling and control population levels of other organisms, while others can be harmful to plants, animals, and humans.
