a Kofoidinium with symbiotic algae ?

[Franz Neidl]

Could it be the dinophycea Kofoidinium (275 µm broad) with symbiotic algae?
The yellow sphere has a diameter from 30 µm. Are these so called "zooxanthellae" ? I read about Symbiodinium, but I dont know them exactly.

This first picture is a stack from 4 pics. But the flagella are really two as you see than in the picture with phase contrast (which is not a stack).

Nice pictures. I cannot speak to this species, but in coral zooxanthellae looks like this:
