This image was made from samples taken during a scientific cruise in the Pacific. Water was filtered to concentrate the organisms that were present, then dried onto a thin sheet of plastic and then shadowed with a fine layer of metal to provide contrast. The preparation was then observed with an electron-microscope. This technique has been used to document the diversity of marine microbes, especially, protists in the oceans.
-
Adenoides spec., a so far undescribed taxon. Left lateral view, mid cell focus, note the granula reserve material in the cell.
-
Left lateral view, mid cell focus. Note the centrally located nucleus and storage material (granules).
-
Adenoides (add-en-oi-dees) eludens (Herdman) Balech 1956. The image on the left shows the left lateral view of a cell, with yellow-brown plastids with a ring -like pyrenoid. The small epicone is almost not visible. The image on the right shows a mid-focus plane through a cell, with a pusule near the anterior end and the nucleus near the posterior end.

-
Adenoides eludens (Herdman) Balech 1956 is shown here from its right lateral cell side. Note the large pusule in the upper part of the cell and the nucleus in the lower part.
-
Right lateral view. Note the ring-like structure. It is a starch sheath around the pyrenoid, a structure of the plastid.
-
Mid cell focus showing the nucleus in the lower part of the cell and the pusule in the upper half.
-
Sabulodinium (sab-you-low-din-ee-um) undulatum Saunders & Dodge 1984. The image shows a cell in left lateral view. The cell is laterally compressed. The cingulum is near the anterior end of the cell. There are no plastids visible, however a reddish food particle is visible. The cell is thecate. The nucleus is in the posterior of the cell.

Dinophysis (die-know-fie-sis), common dinoflagellate in marine water column. This individual is clearly heterotrophic. Differential interference contrast.
-
Two cells close to completing division.
-
D. acuminata has an oval cell shape. The posterior end of the theca can bear small teeths. The left sulcal list is well developed and of a similar depth along its length. The pore structure is usually finer than in species such as D. norvegica, but is variable.
-
It is often confused with D. norvegica. However, the widest part of the cell lies further posteriorly than in D. norvegica, with a blunt antapical tip. Length: 54-94 microns.
-
Cell rounded-oval to circular, laterally strongly compressed, length: 36-56mm. The anterior end extends slightly beyond the list bordering the girdle. The theca has a fine pore structure. Chromatophores are absent
-
Dinophysis sphaerica.
-
-
Ornithocercus magnificus.
-
Sinophysis microcephalus observed in marine muds and sandy sediments in the vicinity of Broome, Western Australia in September 2003. This image was taken using phase contrast optics. This work was supported by the Australian Biological Resources Study.
-
Prorocentrum micans (pro-row-sent-rum my-cans) a marine dinoflagellate, atypical in shape. This genus is associated with toxin production. Differential interference contrast.
