Hi Carlos,

It's much to large for D. tuberculata. Can you show it in lateral view? I'm very anxious to see this one.

Cheers,

Ferry

Thank you Ferry.
Unfortunately I do not have another video of this amoeba.
It was perfectly spherical, smooth, of an intense brown color.
I hope this information serves to you for something!
A big greeting
carlos

Was it spherical or ovoid?

Well, in that case it is a very interesting amoeba. Spherical and more than 300 um, wow! Could well be an undescribed species... :D

Hi Ferry, this is a video of two amoebae
of the same species:
http://www.youtube.com/watch?v=3wqeKzuEnkI
The real measurements are approximately 150um of diameter.
Not 300.
It is very difficult to film it in brightfield.
I hope that it should be useful to you to identify it.
I regret having been wrong in the estimation of its length.
Greetings
carlos

Well, it still looks a new species to me, because it is large, spherical AND it has a lobed mouth. I only know the smaller, often spherical Difflugia gramen which is three or four lobed, but completely different from yours. Really amazing, but there are still many new species waiting to be discovered. It is alway thrilling to be the first to see such an amoeba!

This text (pag.14) describes to Difflugia lismorensis var. quinquelobata

http://ia700704.us.archive.org/26/items ... ff1950.pdf

It is found among other areas in Argentina and Uruguay.
All the samples were found resemble him.
Do you think may be the same?
Best regards
