Phyllodoce mucosa-maculata is found in sediments with a wide variety of grain sizes (maximum 500 μm), but displays a preference for sediments with a median grain size between 100 and 300 μm (relative occurrence > 30%). A similar pattern is observed with regard to the mud content preference: Phyllodoce mucosa-maculata is found in sediments with strongly varying mud contents, but prefers sediments with a mud content up to 40% (relative occurrence: minimum 40%).
