Penard in September - Golden Algae and Stramenopiles

Ecki · Post by **Ecki** » Fri Sep 26, 2014 8:39 am

September has been a busy month here at amoeba central! I will spare you details of new amoebae taxa that we have added but will focus on some spectacular golden algae instead.

Golden algae are in the group Stramenopiles (aka Heterokonta). Orginially this group contained species with 2 flagella whereby one of those flagella had little lateral hairs (mastigonemes). Molecular analysis has shown that many more species with no flagellum at all are part of the Stramenopiles. So without any further ado, here are some examples of Stramenopiles (and I won't show Diatoms that are part of this clade, too)

Actinosphaerium eichhornie
Surprisingly, the Actinophrydae (Actinosphaerium and Actinophrys) belong to the Stramenopiles, too. No flagellum here

Ciliophyrs infusionum
This looks like a hybrid of a heliozoan and an amoeba. And guess what, it even has a flagellum!

Cyclonexis sp.
This is a classic golden algae. But if you think, nothing amoebae-like there, let me just whisper "Chrysamoeba"

Chlamydomyxa labyrinthuloides
It has chlorophyll, is heterotroph and moves like a reticulose amoeba.

Kudos to my partner Steffen, who took most of the images in Stramenopiles. October will be a real amoebae month again. There is a lot of new stuff already and we even hid a daily chess puzzle

I hope you enjoy the images.

Best regards

Thank you all.

It is worth looking at Penard.de. I have shown 5 images as a teaser to what is online. I need to get more stuff up before we have winter here

Best regards

Fellow Pmnetters -
It IS worth looking at Penard.de .

Note the stuctures made by, and within, Pinaciophora. Make sure you find the one with 200nm scale.
