Ceratium sp.


These are really interesting as they can photosynthesize and they can also move around with two flagella. Technically dinoflagellates are algae, so it is really amazing to me that they have some independent mobility. I couldn't see the flagella, and they weren't moving when I observed them. I only saw two or three in this sample, and they were fairly large compared to the other organisms in the sample. You can see it in the last photo on the right side.


A marine biologist on board skimmed some plankton using really fine mesh nets and we took a drop from that sample and placed it under a microscope. The sample was skimmed in Izhut Bay just off Afognak Island in somewhat shallow water (less than 200 feet).

I’ve always wanted to see a dinoflagellate. So cool!
