Desmid, Arcella, rotifer (Notommata copeus )

Charles Krebs · Post by **Charles Krebs** » Sat Sep 29, 2012 9:54 pm

Sampled a new location yesterday and came up with some interesting subjects.

One is a rotifer I have not seen before. Quite large, and moved in a slow lumbering manner. Seemed to feed primarily on filamentous alga and appeared capable of "severing" a filament as if cut by shears. Any identification thoughts would be appreciated.
(EDIT: Added the identification for the rotifer. Thanks Michel!)

Charlie,

Outstanding images ! I like Arcella the most.
I somewhen managed to take the photograph of very similar species of the rotifer

. You can find it on my website in "Animals" (number 5).

Micrasterias rotata, I found a lot of them at De Haeck Zegveld in The Netherlands. Great pictures.

Charles, I like such photos very much.
What technique did you used to take #1?
Is it polarized with the polarizer and analyzer being close to be crossed?

Thank you all for the comments.

Yes. Basic polarized, but the polarizers were not crossed to full "extinction".
