Stalked Diatoms

[NikonUser]

Yesterday's sample had the filamentous algae covered with colonies of these stalked diatoms.
Top: one pair in side view
Bottom: View showing rectangular top surface; reminds me of my Nikon flash.

I first thought these were flat but they are actually tapered boxes.
Little dark rods are bacteria.

Nice shots there NU. With winter coming on, I really need to grab some samples and take the dust cover off the Axiostar and get back into a little microscopy. Diatoms are really neat subjects to view and to photograph.

Excellent images. The tops of them are pretty strange. It's amazing what Mother Nature can come up with just through trial and error. Maybe that end is a lens? Concentrating sunlight on the chloroplasts?
