Nematodes, also known as roundworms, are a diverse phylum of invertebrates that inhabit nearly every habitat on Earth. They are found in soil, freshwater, marine environments, and as parasites of plants and animals. Nematodes are characterized by their cylindrical, unsegmented bodies, which are typically small, ranging from microscopic to several millimeters in length, though some can be much larger. Their digestive system is complete, with a mouth at one end and an anus at the other.

The phylum Nematoda contains an estimated one million species, with only a fraction of them having been formally described. Many nematodes are free-living and play crucial roles in ecosystems, such as decomposing organic matter and regulating soil populations. However, a significant number are parasitic, causing diseases in a wide range of hosts. Plant-parasitic nematodes can damage crops, leading to significant agricultural losses, while animal-parasitic nematodes, including humans, can cause various health issues.

Reproduction in nematodes is typically sexual, with distinct male and female individuals. They undergo a life cycle that often involves several larval stages before reaching adulthood. The study of nematodes is important for understanding ecological processes, as well as for developing strategies to control parasitic infections in agriculture and medicine. Their adaptability and widespread presence make them a significant group in the study of biodiversity and biology.
