arturo,

Nicely done! Heliozoans like this are so magnificent to see. Don't count on my identiification ( :wink: ) but my guess would be Raphidophrys (possibly Raphidophrys intermedia or Raphidiophrys elegans).

When I need to adjust the DIC so that the axopodia become clear, it often becomes difficult to avoid overexposing a portion of the "body" of the organism. Since these subjects move so slowly it is sometimes possible to take the best overall exposure, and then quickly take a second exposure a couple of stops darker. The overexposed portion can then be replaced by the section from the darker exposure.

Hi Arturo,

It is impossible to identify small Heliozoa without help of an Electron Microscope. Your Heliozoon is most likely a Pterocystis species, may be Pterocystis anapoda. Your species has platescales and as far as I can see bended spicula, Raphidiophrys species don't have platescales.

Best regards,


Ferry
