This image was made from samples taken during a scientific cruise in the Pacific. Water was filtered to concentrate the organisms that were present, then dried onto a thin sheet of plastic and then shadowed with a fine layer of metal to provide contrast. The preparation was then observed with an electron-microscope. This technique has been used to document the diversity of marine microbes, especially, protists in the oceans.
Botrydium (bot-rid-ee-um), xanthophyte - a group of walled stramenopiles although unlike most stramenopiles with plastids, the xanthophytes have a much greener colour. Botrydium is usually assigned to the Vaucheriales, which are characterised by being able to adopt a coenocytic (multinucleate) body form. Normally grows on mud. Phase contrast.
