Notosolenus (no-toe-so-lean-us) a rigid gliding euglenid. This species, Notosolenus ostium one of the more easily recognised and common species (the deep longitudinal groove is the diagnostic feature). There are two flagella arising within the flagellar pocket, one projects out the front and is easy to see, the other is usually short, directed to the rear, and difficult to see - except perhaps when the cells are turning. With a mouth. Consume algae. Phase contrast. This picture was taken by David Patterson, Linda Amaral Zettler and Virginia Edgcomb of material from the salt marsh at Little Sippewissett (Massachusetts, USA) in Autumn, 2000 and in Spring and summer, 2001.

Notosolenus ostium
From the collection
Little Sippewissett salt marsh, Massachusetts, USA
| Description of Notosolenus ostium: Cells are 18 65 microns long and have a small ingestion organelle, which is obliquely oriented and visible on the ventral face of the cell. The cells have a longitudinal dorsal groove and are slightly concave on the ventral face which has a wide groove and four fine stripes. Two flagella emerge from the flagellar canal and are in unequal length. The anterior flagellum is about 1 - 1.5 times the length of the cell and the posterior flagellum is about 0.2 to 0.6 times the length of the cell. The reservoir is near the front in the right side of the cell and the nucleus is to the left. |
