Bicosoeca (bike-o-so-eek-a), one of only several genera of bicosoecid stramenopiles. This genus includes cells which live within loricae. The cell attaches to the lorica by the tip of a recurrent flagellum, the other flagellum extends out of the lorica and beats with an undulating beat. As with other stramenopiles, the (sub-microscopic) hairs on the flagellum draw a current of water towards the cell, and particles are intercepted by a shoulder, seen to the left of the top of this cell, and ingested. Phase contrast. This image taken by Michele Bahr and David Patterson of material collected from the water column and the margins of Lake Toolik (Alaska, USA) in August, 2001.

Bicosoeca
From the collection
Lake Toolik, Arctic Alaska
| Description of Bicosoeca: Biflagellated cells enclosed within an organic lorica, usually vase shaped. Solitary of colonial, if colonial may be arborescent or ball-shaped. Lorica may attach directly to substrate or have stalk. Anterior margin of cell raised on one side to form a collar. This forms part of the ingestion area. Cells may retract into their lorica by action of the recurrent flagellum, anterior flagellum coils up. Sometimes and incorrectly spelled Bicoeca. About 40 species, freshwater and marine. Type species: B. lacustris, James-Clark, 1867. |
