Description :

Carpediemonas (carp-ee-dee-a-moan-ass) membranifera Ekebom et al., 1996. Cells are elliptical or obovate and 3 to 6 microns long with a longitudinal ventral groove, which extends most of cell length. When squashed, the cell is pliable. Two flagella unequal in length emerge from the anterior distal part of the cell, the anterior flagellum bent over backwards is as long as the cell and beats stiffly. The acronematic posterior flagellum is about 2.5 - 4 times cell length, beats actively in the ventral depression and usually lies in the depression. The cells usually move by skidding with the anterior flagellum beating with a stiff paddling motion. The cells consume bacteria. Commonly observed in anoxic conditions.
