A sip of plankton photographed with visible light (left) and UV-light (right). On the left, a P. danica with filled food vacuole and a few unicellular coccolithophorids with their calcareous scale armour. The unique dinoflagellate nucleus displays oval-shaped chromosomes, which are (almost) always visible whereas all other organisms have such condensed chromosomes only during certain stages of cell fission. Chloroplasts of coccolithophorids light up in vivid red in UV-light (right), which reveals the last bite of the dinoflagellate.
