These are large free-living soil & aquatic nematodes (up to 5 mm in length) and are omnivorous, using a variety of food sources. They have a hollow spear that can pierce other organisms and suck out nutrients. Depending on environmental conditions and food availability, they can feed on algal filaments, protists, other nematodes and then, when their primary food sources are unavailable, switch to feeding on fungal hyphae and bacteria. They often have low reproduction rates and generally occur in stable habitats, rather than in newly established or disturbed habitats.
