Notes: The image contains diverse planktonic organisms, ranging from photosynthetic cyanobacteria and diatoms to many different types of zooplankton, including both holoplankton (permanent residents of the plankton) and meroplankton (termporary residents of the plankton, e.g., fish eggs, crab larvae, worm larvae). It reflects just a bit of the highly diverse life forms that one finds in the planktonic realm.
