Neobodo curvifilus ( Griessmann 1913) Moreira et al. 2004 ( Fig. 2f )

Observation: Cell outline is oval or bean-shaped. The cells are 5 to 8 µm long, flattened, and pliable. The two flagella of unequal length insert subapically to one side in a small pocket. The anterior flagellum is about the cell length, hook shaped, and beats slowly in a broad curve in front of the gliding cell. The trailing posterior flagellum is acronematic and 2.5 to 3 times the cell length. The cells normally glide but may have a squirming movement, and rotate when swimming. Often observed.

Remarks: This species has been described under the name Bodo curvifilis from marine sites in Antarctica, Arctic, north Atlantic, northeast Atlantic, Australia, Denmark, West Greenland and Norway with cell lengths of 4–12 µm ( Griessmann 1913; Throndsen 1969; Turley and Carstens 1991; Vørs 1992a, b, 1993a; Patterson et al. 1993; Tong et al. 1997; Lee and Patterson 2000; Lee et al. 2003). The description is in accord with Vørs (1992a). Neobodo curvifilus is characterized by the curved shape and the paddling beat of the anterior flagellum, thus it is easily distinguished from other species of Neobodo because of these characters.
