Heliozoa

Post by RogelioMoreno »

Here a set of images of what I think is Heliozoa (maybe Actinosphaerium).

Body (without the arms) diameter around 323 microns.

It was very nice to watch the extrusomes (I think that is how they are called) moving along the arms (axopodia).

Nikon 10x/0.45 (crop, the image quality is not as good as the 20x/0.75):

The following images with 20x/0.75:

Beautiful 'research grade' images, and I use this term advisedly, these images would grace any scientific paper.

Rogelio,

Very beautiful images again !
In the end of the last year I managed to take photograph the same, I think, species but in phase contrast. I'll try to find this photograph and send to forum.

Regards

Marek

Very nice detail Rogelio. I have been finding a large number of these in my samples, especially after feeding them dried yeast. I have just recently realized that the spines are quite flexible and not stiff like real needles.
