Rice Scale Collage
Zooplankton vary in size and shape but most are very tiny and require a microscope to view them properly. This collage of zooplankton illustrates their size compared to a grain of rice (middle). Clockwise from top: Limacina helicina, Corycaeus anglicus, Tricornia borealis, Pseudocalanus, Ostracod, Bipinnaria (seastar larvae), Acartia longiremis, Neocalanus plumchrus
