Amoeba? (Marine sample)
Amoeba? (Marine sample)
Came across this the other day while I was looking for a subject to compare the colour fidelity of DIC vs Brightfield viewtopic.php?f=6&t=9619#p82003
Did not notice it at first as I was concentrating on the Diatom.
Never seen one (if it is an amoeba) quite like this, nor can I find anything similar looking.
Would appreciate ID suggestions from anyone with an interest in amoebae

Re: Amoeba? (Marine sample)
Really strange thing 75RR. Would be important to see if the object moves or change the pseudopodia.

Just looked at the original video again. It it 5 minutes long and during that time I could not discern any movement.
However if you look at the two images below one can see that 'it' is no longer in the same position in each image.
Perhaps not an amoeba after all.

Choanoflagellate Colony? Dead or nearly so.
Re: Amoeba? (Marine sample)
Thanks Zuul
Had thought of Choanoflagellate but the shape does not seem quite right, missing the funnel and flagella + this seems to have a body.
Still, something along those lines is probably right.
Perhaps an anemone?

Re: Amoeba? (Marine sample)
You can see it's vacuoles appearing and disappearing which suggests it's an amoeba.

Has anyone had contact with Ferry Siemensma from Microworld - https://www.arcella.nl/contact/ Would he mind if I asked him?

Re: Amoeba? (Marine sample)
Wow! It’s beautiful. I think it is an amoeba because of the presence of various vacuoles and organelles, and I think there is a contractile vacuole (only one) which is a quantity that I believe is characteristic to amoebae. It kind of looks like an amoeba in a stage where is is about to/in preparation to divide. If you go to Ferry Siemensma’s website, search “Amoeba proteus” and look at the drawn diagrams, there is an image quite similar to your video. So perhaps it is Amoeba proteus in preparation for division? It is incredible, thank you for sharing!

Thanks mazo4033

Amoeba proteus: A-C polypodial locomotion; D monopodial locomotion; E amoeba in preparation for division; F bipyramidal crystal; G plate-shaped crystal; H clustered crystals.
Good catch! Don't recall seeing that image - here is a link to it:

Re: Amoeba? (Marine sample)
Though I still think that this might be an amoeba preparing for division, given that it looks very similar to that, I do have an interesting image. I had been reading the book Handbook of Protozoology by Richard Kudo when I encountered an organism of a shape similar to one I had only seen once before, in this post:
This organism is more shell-like, I believe, imagine like Radiolaria or Forminifera, which is why I don’t think it is the organism that you found, but I thought this was an interesting thing worth posting about

Re: Amoeba? (Marine sample)
Hi mazo4033, it is curious how one finds similar 'shapes' in distinct organisms.
Thanks for the image
