Mononchidae
Mononchidae is a family of predatory nematodes belonging to the order Mononchida. These soil-dwelling roundworms are characterized by their prominent buccal cavity armature, which typically includes a single, large, dorsal tooth. This tooth is used to pierce and tear the bodies of their prey, which mainly consists of other nematodes. Mononchids are found in a wide variety of terrestrial habitats, from agricultural soils to forests and grasslands. Their predatory nature plays a significant role in regulating populations of other soil invertebrates, particularly other nematode species. This makes them ecologically important in soil food webs.
The family Mononchidae encompasses several genera, including Mononchus, Anatonchus, and Miconchus, each with distinct morphological features
