Question on two species.(Image #6, #7 and #8: Very long chain diatom.) Is this Rhizosolenia?Last image: Unknown or is it Pleurosigma?Your ID's are right on the money. Great job!As for the last picture, it is not a Pleurosigma. If it does not have fine spines at either end then it is a Navicula spp. If there are spines then it is a Nitzschia spp. I cannot tell from the picture if there are

Garden variety video footage of a Rhizosolenia.In this footage the Rhizosolenia has floated above the debris (as you can see the debris below is out of focus). The Rhizosolenia is in clear focus.

Here are two Guinardia (diatom), and a pair of Rhizosolenia in the process of a cell division or mating. Some diatoms reproduce sexually and asexually.

This appears to be two Rhizosolenia diatoms either in the process of mating, or an asexual cell division.This contains a higher magnification of the Rhizosolenia diatom as a pair, either in the process of sexual reproduction or asexual cell division.
