Details of the wall surface, specimen oriented the aperture up |
Remarks: | The agglutinated test wall incorporates sponge spicules; on the Barents-Kara shelf this species has been recorded only from the SW Barents Sea at depths of 100-300m where sponge-spicule mats of several centimeters thick commonly drape the seafloor; never found in sediment cores. |
