    Distribution:

    The family Desmodoridae has a large number of species, of which  very few have been described. Ecological studies on marine nematodes record nematodes of the Desmodoridae in deep-sea sediments, usually in low numbers, with their relative abundance reaching a maximum of 1% of the total mass (Soetaert and Heip, 1995).

     Reported fronm the Northeast coast of India: at Divi point (250m) and Barua (250m). Also from the Northumberland coast, Northeast England (sublittoral Fine Sand) (as D. norvegica Allgen, 1932 in that report).,
