A very common and species rich free-living genus in intertidal zone and
continental slope regions, particularly sandy-silts in the upper rgions of the continental slope.
Also found in deep sea regions.
The White Sea is a small marginal shelf sea separated from the Arctic Ocean
by the shallow and narrow Gorlo Strait. In
its deepest regions (small depressions with a maximum depth of 343 m): the
deep water is very cold (about -1.5 ï¿½C) and not fully saline (29.5-30.0 %).
Samples collected at a depth of 251-288 m had 59 nematode morphotypes
belonging to 37 genera and 18 families. he genera Sabatieria and Filipjeva dominated
at all samples, followed by Aponema, Desmoscolex,
and Quadricoma. The
composition of the dominant genera is considered typical for this depth
range in temperate and Arctic waters (Miljutin et al., 2014).
been characterized as the most common dominant genus on the ocean shelf
Often it has been recorded as one of the most abundant genera from the lower
shelf to the medium slope and in canyons in the temperate and Arctic waters(Miljutin
et al., 2014).
