Aturo,

nice picture.

is it a Centropyxis aculeata?

It was, when it was alive. This looks like an empty shell.

Regards

Hi Arturo--
It's a beautiful photograph, but are you guys sure that test is empty? It appears that there's quite a bit of stuff inside the shell. Although I don't see any pseudopodia emerging, so maybe the shell has some debris inside it?

Hi David,
i'm sure that it'is not alive. I observed that slide for a long time and shell did not move at all, so I assumed it was dead.
. but there are a lot of debris inside like green algas, diatoms frustules etc.
