Some zooplankton and a stereo diatom

This last one is a crab larva. I included a small overall frontal shot here for reference, but you can see the whole critter much better here, here, and a stereo version here.

Hello Charles,

I am always very much impressed by your pictures.
I would like to know if the first picture is a DIC picture or only a darkfield picture?; is it stacked?; how many pictures? what objective and what condenser did you use for it?

Thank you for posting your interesting animals!

Franz

Quite beautiful. The stereo diatom is especially striking.

Thanks all!

Franz,

I would like to know if the first picture is a DIC picture or only a darkfield picture?; is it stacked?; how many pictures? what objective and what condenser did you use for it?

That is a stack of 4 images. Regular darkfield. I used my Olympus BH2-UCD condenser with a circular "stop" placed in one of the turret positions. I can use my 4X and 10X for darkfield this way. This was taken with the S Plan Apo 10/0.40.

What are the first two animals?

I'll tell you what I think they are...

but my marine ID's are always suspect and I am always ready to hear from more knowledgeable individuals...

The first one is a pluteus larva of an echinoderm. I suspect either a sand dollar or sea urchin. The mouth is the small triangular opening at the base of the "arrowhead-like" structure.

The second is a small medusa of a cnidarian (jellyfish).

Amazing! #3 is like a color plate from a 19th century natural history text!

Beautiful shots. Does anyone know what is the species of the Diatom? Or maybe the genera?
