Testate amoeba (Euglypha?)
I always seem to find the nice looking amoeba tests at the bottom of a wet mount, much too far away from the cover slip to allow me to use the 40X. So this is a crop from a shot made with a 20X. Not the greatest image, but a cool looking test.

Charlie you probably could have shot it with a magnifying glass and a vintage 1950's Kodak Brownie and it would still come out looking good. Got to agree with Graham there, can't say as if I have seen one of these either. I have got to get back to spending more time at the scope. Thanks Charlie!So this is a crop from a shot made with a 20X. Not the greatest image, but a cool looking test.

Yes, yes, yes, I know that I have deserted from my true passion for a while but it is summer! I want to walk through the fields! And unfortunately I also have quite a lot of work at the moment. Shouldn't complain too much, just been to Brittany, France. Nice for tide pool photography!
And you seem to be able to fill the forum on your own, Charlie!

Hhmm... Charlie's image is vastly better than anything else I can find on the web, but I see a couple of differences I can't account for by image quality.bernhardinho wrote:I think this is a Trinema enchelys.
One difference is that Charlie's test has a symmetric opening bordered by prominent regular teeth, where all the images at http://protist.i.hosei.ac.jp/pdb/Images ... index.html show an asymmetric, almost "hooded" shape with a smooth margin at the opening.
The other difference is that Charlie's test has those six prominent spicules (is that the right term?), where I can't see anything like them in the other pictures.
Bear in mind, I'm essentially clueless about testate amoebae and I'm just responding to what I can see. But I'd sure be interested to hear people's thoughts.

Bernhard and Rik... I think it is Euglypha alveolata, based on Plate 35 at this site:

Steve Neeley recently put this together from the work of Joseph Leidy. It is a super site and a "must" to have bookmarked if this subject matter is of any interest. Thanks again Steve!

I find it intriguing that this excellent reference dates from 1879!
