Here a picture of what I think is Acanthocystis:

Very nice Rogelio. Were the drops moving down the spines?

I'm wondering, are you able to use polarized light with DIC?

Mitch,

Thank you.

Sorry; but I did not track the them so I do not know if they were moving.

DIC is based on polarized light.

Very nice. I'm interested in how you added flash to your TE300.

The correct name is Choanocystis aculeata. The former name was indeed Acanthocystis aculeata, but the name Acanthocystis is now applied to species with spines with a central placed base. C. aculeata has spines with a base which resembles the leaf of a waterlily. The sad news is that positive identification of most Helizoans is only possible with an Electron Microscope. Within some weeks I will put Electron Microscopical pictures of Heliozoans on my website.

Rogelio, excellent again!

(perhaps if you may lower a bit the highlights brighness the result would be even better)
