, a stramenopile flagellate (the feeding flagellum has stiff hairs and its activity draws water to the cell) living within a stalked egg-cup shaped lorica. The feeding flagellum projects out of the lorica (most of these cells have contracted into their loricas). The cell often has a lip alongside the site of flagellar insertion. A second flagellum arises at the front of the cell, curves over the cell body and attached the cell to the bottom of the lorica. This flagellum can contract and draw the cell quickly into the lorica. This genus also often reported under the name Bicoeca
