In this video, the Coscinodiscus is laying flat, and currents in the water cause the Coscinodiscus to move and turn on its side, revealing its true three dimensional shape.
These are just a few of the many great angles caught on Coscinodiscus. A more extensive collection of photos is available on the Coscinodiscus Blog.
This is an interesting little critter. It is sweeping organisms around it, and causing a swirling motion in the water.
A common diatom. I haven't been able to identify yet. I've seen a lot of these.
Nice work,

The yellow disk is a Coscinodiscus, the purple oval disk is Oblea and the sticklike branch is Thalassionema.
More of the mysterious purple oval disk.

Dr. Morton says that the pink compressed dinoflagellate is Oblea with a super big food vacuole. So neat!!!
