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.

Thanks all!
Franz,

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).

Franz,
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.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?

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...What are the first two animals?
