Telonema subtilis Griessmann 1913 ( Fig. 4m View Fig )

Observation: Cell outline is oval-ovoid. Cells are about 8 µm long, anteriorly narrow and posteriorly broad with a short anterior neck. Two flagella insert below the neck, and are acronematic and slightly longer than the cell. The nucleus is centrally located. The cells swim backward with the flagella, which point behind the swimming cells. Food materials are shown in the posterior end of the cell. Not common. Three cells were observed.

Remarks: The observations are in accord with Griessmann (1913). This species has been found at marine sites in France, Mediterranean, Arctic Norway, Australia, Arctic Canada, Greenland, Japan, Belize and Gulf of Finland (Grieessmann 1913; Hollande and Cachon 1950; Throndson 1969, 1983; Vørs 1992a, b, 1993a, b; Patterson et al. 1993; Tong et al. 1998; Vørs et al. 1995; Lee et al. 2003), and has also been reported from a freshwater site in the Antarctic ( Tong et al. 1997). Previously cell lengths were observed to be 4 to 18 µm. Ultrastructural studies were conducted by Vørs (1992a) and Yabuki et al. (2013). This species is distinguished from Telonema antarctica Thomsen in Vørs 1992 by the cell shape. Telonema antarctica is reniforme.
