Distribution:

Free-living marine nematodes reported from cold seeps in the Gulf of Cadiz (west of the strait of Gibraltar) and from the eastern Antarctic ocean.

Cold seep ecosystems derive their primary metabolic energy from chemical processes rather than sediments of plant material.  The habitats have a typical meiofauna in which nematodes are generally the predominant metazoan taxon. Species diversity is generally low in these habitats due to toxic conditions created by high sulfide and low oxygen levels (Bezerra et al., 2013).
