A very odd looking amoeba!

Post by Charles Krebs »

I haven't seen anything quite like it before. While scanning the slide quickly at low mag I thought it was an unusual ciliate of some type, but when I looked more closely it appeared to be an amoeba.
Any ID thoughts welcomed. My guess for now is that it might be a testate amoeba with no test.

Unusual Charlie, Jahns has a few that look similar but no match. Having plasmodia on my mind this time of year, I am inclined to think that it could be two fused amoeba instead of one. :lol: However who knows, maybe you have the formation of a new plasmodium going on there. The reason being is that it does resemble the plasmodia of a slime mold at the edges. Anyway you got me stumped Charlie. :-k Got any more photos of it at a lower mag? :D

Charlie and Ken--

I hope someone has an ID for this one, since they are showing up in my pond cultures as well.

Looking at the overall shot of the amoeba and comparing it to what I find in Jahns, it somewhat resembles some of the organisms in the Family Flabellulidae (page 157 Jahns Second Edition, Jahn Bovee Jahn). However these are mostly marine but Jahns lists at least one in freshwater. Still not quite sure where this amoeba belongs. :-k

Hi Charles, Very interesting! Could that be a small flagellum in the first image? I believe amoebae are related to certain types of flagellates.

I can't post at the moment. Something wrong with my server.

Good eye Wim :wink: If that is a flagellum, the possiblity of it being a Mastigamoeba is good. Although I do not notice any bacteria attached to the pseudopodia, they do not necessarily have to be present, nor does a uriod. :)

Yup! I've got a new pair of glasses :shock: :)

I can't upload anything for a week now. My provider has technical problems. So I think I'll have a small posting holiday and let you folks do all the work:)
