Morphology and Anatomy:

Members of the subfamily Diplolaimellinae of the Monhysteridae are characterized by a double buccal cavity at some point during their juvenile or adult stages, while those in the other subfamily, the Monhysterinae, have a single tapered buccal cavity.

Distribution:

Free-living marine nematodes. Halomonhystera is an opportunistic genus that colonizes a wide range of habitats from intertidal
seaweeds to ship hulls, food falls, cold seeps and hydrothermal vents  (Leduc, 2025).

Feeding:

Food Sources and Feeding strategies for the genus Halomonhystera

Bacterial and probably epistrate feeders. The presence of several diatom in the intestine of H. refringens, for example, indicates the ability to feed on
microalgae that grow among filamentous seaweed covering surfaces. Halomonhystera disjuncta has also been shown to feed on diatoms and other algae (Leduc, 2025).
