Description
Cells colorless, with tentacles emanating from the cell in all directions but particu lar ly n u- merous at the front end. Tentacles of the front end interconnected by complex system of fibers (Larsen , 1985) . With well-developed flagellar wing supported by paraxonemal rod. Het- erotrophic . Very common in marine plankton . One well-described species . Actinomonas mirabillis Kent, 1880 (Fig. SA). Cells 4-8 1--lm in diameter. With trailing stalk up to c. 120 1--lm long . Sometimes more than one trailing stalk present. With annu lar scales on the flagellum. Ultrastructural study by Larsen (1985 , as Actinomonas pusil/a). Parapedinella reticulata S. M. Pedersen and Thomsen somewhat resembles Actinomonas. It has numerous tenta- cles emanating from the cell surface but the cell , which is 7-1 5 1--lm in diameter, is covered with plate -like organic scales (Pedersen et al. 1986) . Annular scales are present on the flag- ellar surface . Known from Australia and Den- mark .
