Re: Foraminifera
Amazing view. I am trying to correlate the live creature with its test. Does it consist of a brown spiral frontal part and a mesh-like, larger back part ?
Re: Foraminifera
Perhaps this stacked image of it might help.

Re: Foraminifera
Thanks, yes, this is a clearer presentation!
Re: Foraminifera
Very Cool -- is that a living foram I see??
Foraminiferae have their similarities to the diatoms: both create tiny "seashells", and most illustrations show only the shell and rather make a mystery of the organisms that live(d) in them. Forams are amoeboid creatures, but make shells that really bring chambered nautilus type animals to mind, wonder why?
How was this specimen collected?

Re: Foraminifera
Thanks KurtM, yes live. Not my first live one but the first time I manage to see and photograph/video an inhabitant's axopedia.
Sample consists of small rocks with algae attached which I picked up at low tide.
Most probably washed in from deeper water but not too deep, sea is shallow for a fair way on this part of the coast. So benthic rather than planktonic.

Re: Foraminifera
For anyone wondering what I meant by non dedicated DIC Slider (on the video description), it means that I used a DIC slider that was not intended for the objective.
DIC systems vary a lot. In the one I have each DIC slider has printed on it the specific objective it is designed to work with.
Having more objectives than sliders has led to a little experimentation. Results tend to vary, ranging from very good to not at all.
On this occasion I used a Plan 40x/0.65 slider with a Neofluar 25x/60 objective.
Here is a link to a thread on photomacrography.net by Cactusdave that documents the results he obtained.
