Marine nematodes. Frequently found with supralittoral or intertidal marine fauna, but also in the deep sea.  Coral fragments are an ideal substrate.

Nematodes of the Epsilonematidae are adapted to functioning and surviving in environments with strong current through the dapatation of adhesive and ambulatory setae  Frequently they have been found associated with and adhering to coral and sponge fragments as well as in sediments.
