What is it, please?

This creature was rolling about in some pond water. The original magnification was 600X. The creature's diameter is just a bit less than the width of a Spirogyra stalk.

Thanks for the help.

Hi Jim

although the image is rather feeble let's say I would venture the guess Synura uvella.

Cheers Bernhard

Bernhard, i usually do not post blurred images, you usually do not post
fuzzy IDs.....

This is definitely not Synura, i guess it is a free swimming colony of
Anthophysis....

Thanks for looking,

Hi Gerd

well, quite interesting. I would love to know what makes you so sure to "definitely" exclude Synura on the base of a not to tell-tale pic

Anthophysis is interesting, I 've never seen it. The pics in the "Wassertropfen" look very diferent, so that would never have crossed my mind.

Cheers

Bernhard

Thanks for the I.D.s My latest batch of pond water just turned rancid and is fairly teeming with these colonies and countless tiny paramecia.

I tried to get better photos of the colonies at 150x and cropping tightly, but there isn't enough depth of field this way either so far. The water will stay rancid for a while so I can take another hundred shots or so to see if I can get better results.
