Algae ?

[Grahame]

Hi folks,
Haven't seen anything similar to this.
It wasn't moving.
In the rubble in the bottom of a fresh water animal trough.
Some sort of brown algae ?
40X achromat, 6 images stacked.
Thanks

Grahame,
maybe it is Diplophrys archeri because of the yellow oil bubbles? But it is more a guess, difficult to conclude from the photo. Also the Filopodia of the amoebea are missing on the photo?

You may want to check the link below, I have made some photos from this amaboea there:

Hi ImperatorRex,
Thanks for the suggestion and the link to your observation.
It was an interesting read.
The images and the ones at
https://www.arcella.nl/diplophrys-archeri
Had me thinking it may possibly be one with the filopodia retracted.
Then I had a look at NZOR (New Zealand Organisms Register)
http://www.nzor.org.nz
It appears these have not been recorded from NZ so far.
There are no other Diplophrys there and 2 Amphitrema, but they don't look anything like it and the habitat is wrong.
So I guess it still remains an unknown, though some form of amoeba is a good thought.
Cheers
Grahame
