A family of free-living marine nematodes from intertidal waters, estuarine areas and mangroves.

• Inhabit marine environments (intertidal, shallow water and deep sea sediments) and brackish water, rarely freshwater.

• Feed as carnivores (predators) or on diatoms and algae

• Metanemes, filamentous stretch receptors, present in the epidermal chords, thought to co-ordinate movement. The metanemes are almost exclusively ventrolateral loxometamenes of Type II.  Many taxa in this group exhibit whip-like movements of the body when anchored at the spinneret.

• Cephalic capsule absent

• Anterior sensilla 6+10 (2 circles)

• Amphid fovea spiral

• Buccal cavity with one or more chambers, teeth usually present

• Pharynx cylindrical, conoid

• Excretory system present or absent
