What are nematodes primarily known as?

Nematodes, often referred to as microscopic roundworms, are a diverse group of organisms that can be found in various environments, including soil and aquatic habitats. They play different roles in their ecosystems; however, their primary characteristic that distinguishes them from other organisms is their round, elongated body shape and their microscopic size.

Recognizing nematodes as microscopic roundworms highlights their physical attributes, which are central to understanding their biology and ecology. They are not visible to the naked eye and require microscopic examination to be observed. This characteristic makes them unique compared to beneficial insects, microbial pests, or parasitic fungi, which are typically larger or distinctly different in form and function. While some nematodes can be beneficial to plants, others can be harmful, causing diseases and damage. Understanding their classification as roundworms gives a clearer context to their study and the various roles they play in agriculture and ecology.
