Present work stands as the first study on the distribution patterns of nematodes along water depths between 75 m and 300 m at the ISBS and gives information on the variability of the trophic relationships of nematodes with oxygen depletion and the presence of toxic hydrogen sulfide in the environment. Nematodes were represented by 137 species from 63 genera and 30 families at the studied depths. 34 species were reported for the first time from Turkey. The presented results showed that most of the nematode species in this region were identified only to the genus and even only to the family or order level. This suggested that the fauna of free-living nematodes of the Black Sea as a whole is much more diverse than is currently known, and requires further taxonomic studies. (c) 2021 Elsevier B.V.
