nematode biology

Nematodes, commonly known as roundworms, are unsegmented, cylindrical organisms found in diverse environments, from soil to oceans. They can be microscopic or several centimeters long. Nematodes have a simple body structure with a tough outer cuticle, a digestive system, and a nervous system. They play critical roles in ecosystems, aiding in nutrient cycling and soil health. Some nematodes are beneficial, helping control pests, while others can cause diseases in plants and animals. Their resilience and adaptability make them an important group in both ecological research and agriculture.
