Different forms of Chaetoceros-diatoms

To the left is a cell of Chaetoceros danicus. To the right is a spirally formed chain colony of Chaetoceros curvisetus.
In the closeup to the left, the opening between the cells of Chaetoceros cf. brevis are seen clearly. The middle picture shows Chaetoceros tenuissimus, where the cells are solitary. On the right, Chaetoceros constrictus is seen. It has produced spores to rest upon while it waits for better conditions.

On the left - Chaetoceros eibenii, which builds colonies that are straight. On the right - Chaetoceros socialis, which builds long colonies that are sparsely spooled.
