.
Plan 40x/0.65, DIC, 430µm length, stacked and stitched in Photoshop, Marine sample, Alboran Sea

Curiously rather greener than most diatoms tend to be.

Great work!

I quite like this one. Looks a bit irregular for a diatom.

It is quite unusual - clue is in the species name.

I think it is pretending to be a desmid ;)

Interesting. So much like algae. How do you differentiate this diatom from algae?

Partly because I knew what it looked like as it is on the diatom list for my area.

Also it is easier to see with a little more magnification.

This is part of one taken with my Planapo 63x a couple of days ago. Unfortunately it would not keep still so I could not get it to stack nicely nor stitch

Amazing! That last image really shows the "undulatum" feature very well.

Hi Glen,
great find and great image! This is really a very special diatom!
No need for a 50µ plancton net here...
