''Paradasys subterraneus'' is a Gastrotricha with a bodylength up to 0.6 mm. The species is marine.

Morphology

Gastrotricha are microscopic animals ranging from 0.06-3.0 mm in body length. ''Paradasys subterraneus'' has a bodylength up to 0.6 mm (Karling 1954).

Ecology

Gastrotricha are aquatic free-living worms, belonging to the benthic meiofauna. They have a high density in marine sediments and are often among top three of meiofauna found here, only surpassed by nematoda and harpacticoid Copepoda. The density of Gastrotrica can be as high as 364 individuals/10 cm2. Distribution of ''Paradasys subterraneus'': British Isles, East North Atlantic, European waters (

Systematics

The phylogenetic relationships of the Gastrotricha are still unclear: Morphological studies place Gastrostricha near the Gnathostomulida, the Rotifera, or the Nematoda. Molecular data have shown that the Gastrotricha are sister taxon to the Platyhelminthes. Later studies have placed them elsewhere, including close to the Ecdysozoa or the Lophotrochozoa.
