Background Here, insight is provided into the present knowledge on free-living nematodes
associated with chemosynthetic environments in the deep sea. It was investigated if the
same trends of high standing stock, low diversity, and the dominance of a specialized fauna,
as observed for macro-invertebrates, are also present in the nematodes in both vents and
seeps. Methodology This review is based on existing literature, in combination with
integrated analysis of datasets, obtained through the Census of Marine Life program on …
