Apertural view 

Collected: 23 Aug. 1991, RV Dalnie Zelentsy, Franz Josef Land sounds, 265 mwd, modern mud
Remarks: Common for muddy sediments in seafloor depressions of the open Barents-Kara shelf, where M.barleeanus often dominates calcareous foraminiferal assemblages; avoids areas with reduced bottom-water salinities; infaunal; believed to thrive on altered, buried organic matter.
